Decided I'm going with Flo for my wheelset and now just need to narrow it down further. Curious if anyone has the 45's, or input on 45 vs 60 front? As for me, I'm 5'9 and ~165 lbs. Definitely not a really experienced rider, so I'm passing on the 90 front. Never rode deep wheels so I don't know if 60/90 will be an issue or not. Would possibly put them on my road bike early in the season but then strictly tris through the rest of the season. I guess just wondering if the 45/60 setup is close enough to 60/90 that the difference is marginalor, or not. I will also have a Powertap gs hub on the rear.

Thanks for the interest. Most people can confidently handle a front FLO 60 wheel in anything but the worst wind conditions. That said, even a training wheel is hard to control in the worst wind conditions. The 60/90 is our best selling combo, but he 45/60 is also a great option, especially if you are going to put them on a road bike and log your winter miles on them. The shallower front wheel will be even easier to control, without sacrificing much speed.

I'm currently riding a 45/45 set on my road bike and really love that wheel set. I think for an all around road/tri set, the 45/60 would be great. Additionally, now that we sell the 60 rims, you can easily have your powertap built in.

One last thing to remember if you are a tentative rider in windy conditions, is that having a rear wheel deeper than your front wheel actually helps stabilize you. The increased surface area at the back end of your bike moves your center of pressure backwards, which increases stability. Just something to keep in mind if you were considering 60/60 and are a timid rider.

Please let me know if you have any additional questions.

Take care,

Top Posts

It’s been a month since Devon’s first ride on the FLO 60s. And since that time, both Devon and Mike have had the opportunity to put quite a few miles on this wheelset. Overall, both of them couldn’t be happier. While this might spoil the rest of the review, we’ll say right now that this is an absolutely terrific wheelset (even before you take into account that you can get the entire set for under a grand, $898 to be exact).

IMG_0467

The Design

Flo Cycling’s belief is that you should be able to buy a great aero wheelset without selling your first born. To do this, the guys at Flo crafted a wheel with an aluminum brake track (no, this is not always a bad thing) and attached carbon fiber toroidal fairing around it. And as a side note, Flo uses hubs that spin far better than the price of these wheels should even deem possible.

IMG_0537

To design the fairing, they made use of Computational Fluid Dynamic (CFD) modeling to avoid the cost and complexity of using a wind tunnel. Using CFD allows a company to create a design, test it, and then refine and retest in hours instead of days. Additionally, CFD allowed Flo to simulate an infinite number of wind speeds and yaw angles to create the shape they felt was best suited for their customers—at a cost far below what its competitors spent (a savings passed on the customer).

The end result is one heck of a wheel.

The Pros

In many ways, riding this wheelset is extremely reminiscent of riding a set of 404 FireCrests. They are extremely fast (Mike set a new PR on his 20 mile TT route) and exceptionally stable (laughing in the face of cross winds). The wide width of these wheels lends to an incredible road feel, as well as providing stability and less rolling resistance. Riders will know the wind is there but will not have to fight it to stay in control. Instead, you can get into a deep TT tuck and punish your legs through the miles.

IMG_0469

These are the type of wheels that genuinely make a rider faster—and for just $898—have truly earned the name “free speed.” To put that price in perspective, for the retail cost of a single set of 404 FCs ($2,725) you can get a Flo 60 Front, Flo 60 Rear, Flo 90 Front, Flo 90 Rear, and a Flo Disc (total: $2,395) and still have money left over to buy Continental GP4000s for the whole lineup.

When riding these wheels you’ll also experience a benefit you may have missed with other carbon wheelsets—sudden deceleration (A.K.A. braking power). While the majority of the transition area has moved toward full-carbon wheels, it’s easy to forget that braking on an aluminum track will outperform carbon. The Flos did not disappoint. They stop like you have a grappling hook attached to your seat stays. This is something that we had sincerely missed when we were tucked deep into our aero bars and needed to panic stop. The 60s brought it all back. Additionally, with an aluminum brake track you need not worry about warping or power loss due to heat buildup.

IMG_0540

We also need to mention the strength of these wheels. There is an unmistakable feeling of solidity throughout the Flo 60. These aren’t your typical super wheels, which fly down the tarmac but snap when your “I’ll-have-the-foot-long chili-dog” buddy looks in their direction. Instead, the Flos are your dependable workhorse with speed to spare. The wheelset we were given to review was the standard non-Clydesdale version, and Mike’s 200-pound frame (the upper boundary of Flos standard wheels) caused no issues with the wheelset. Here at AG we love quality and dependability in a product, and these wheels match that description perfectly.

The (Slight) Cons

The one downside to the 60s is the weight. The wheelset measured in at 2049g, including rim tape. Unfortunately, lightweight wheels these are not. However, we can honestly say that this was not a problem for the vast majority of riding during our test period. However, Devon did notice in his early rides that climbing may be an issue with this wheelset. To that end, Mike performed our standard climbing test on his final day of testing.

IMG_0569

If you have ever ventured down to sunny South Florida you’ll notice that one of the geological features missing here is hills. In fact we have only two kinds of hills—highway overpasses and converted garbage dumps. Strangely, the AG staff prefers to do our hill workouts on the latter. Our local converted garbage dump is absolutely perfect for interval hill workouts. There is a 1/4 mile flat run-up to the hill where you simulate coming out of a U-turn and instantaneously accelerate up to race pace. This is followed by a hard 135-degree turn (where you lose most of your speed) back to a short ¼-mile climb at a max grade of 9%. (Note: If any of our local readers would like to join us on one of these workouts we’d love to have the company).

IMG_0563

Since this course emphasizes climbing ability as well as 5-20mph acceleration, this was a test designed to reward lighter wheels and to find fault with heavier wheels. So how did they 60s do? They were a little troublesome to get to speed coming out of the U-turn, but once they were going, they wanted to just keep going harder and harder. And thanks to the strong braking surface, you could wait until the very last moment to brake for the 135-degree turn. Unfortunately that did mean that you hit that hill with almost zero forward momentum and had to haul the wheels up the hill (yes, you can feel that weight). But would that stop us from buying the wheels? Absolutely not. Again, this was a test meant to simulate worst-case scenarios for a wheelset, and as Devon said in his first-look article, climbing wheels these are not.

The only other complaint that Mike had about these wheels was something that Devon actually found appealing. Devon described the wheel noise as “the bike sounding as if it’s powered by dilithium crystals at 30mph.” Mike simply recalled it as a whistle. After one hundred miles or so you tend to get used to it, but it does catch you by surprise the first time you hear it.

Final Verdict

I am sure anyone that has made it this far into the review will recognize that we were smitten with this wheelset. We recognize that as far as wheelsets go, it wasn’t perfect, but it was very close. On top of that, when you consider just what an amazing bargain you’re getting, it’s extremely hard to find a reason not to pick up a set. As Devon said in his first article, affordable aero is about being fast without a second mortgage. And in just about every way the Flo 60s are the epitome of that credo.

IMG_20130130_100550

[Editor’s Note: In future wheel reviews you will start seeing a score along with the review covering areas such as Acceleration, Braking, Climbing, Cruising, Stability, Cornering and Price. These individual scores will be used to calculate a total score, as well as an “affordable aero” score. However, to give proper reference, we did not feel it was fair to release the scores for the Flos until we could release five wheel scores at the same time. Look for an article toward the beginning of April covering the AeroGeek scoring system for wheels, as well as scores for the Flos, Mad Fibers, and other wheels we have been testing.]

Flo 60 Carbon clincher wheel rims 1500 mile review

RBA Test: Flo 60 Wheels

Three years ago Chris Thornham was your typical triathlete who, like everyone else, wanted a set of race wheels that didn’t cost him an arm and a leg. But, he ended up purchasing a fancy pair of hoops for a hefty sum anyway, and then showed them to his twin brother Jon. ‘Jon nearly passed out when he learned how much they cost,’ Chris recalls. ‘We then thought, ?Hey, we could probably start our own company and sell wheels for cheaper.” Not just a couple of budget-minded bike geeks, the Thornham brothers are both mechanical engineers. And rather than simply source rims, hubs and spokes from an Asian manufacturing catalog, they wanted to compete with the big boys and design their own products from the ground up, all while still maintaining a superlow price point. Flo Cycling was born to offer customers superior aerodynamic benefits without putting too big of a dent in their wallets. Sound too good to be true? Read on.

THE TECH
The co-molded 60 wheel uses an aluminum rim and 3K carbon fairing that the brothers designed using CFD (Computational Fluid Dynamics) software, and then tested inside North Carolina’s A2 wind tunnel. When all is said and done, the 60 rims measure 60mm deep, 28mm wide and weigh 2036 grams for the set (the pair of quick releases weigh 109 grams). The aluminum brake tracks feature an anodized black coating that gives the 60s a stealthy look, something the Thornhams originally hadn’t planned for. ‘We received a set of prototypes from our factory, and they came with black braking surfaces instead of regular silver like we asked for,’ Jon recalls. ‘But after posting photos of them online, our customers started overwhelming us with requests for the black surface, so that’s what we’ve gone with.’

The rims are laced to custom, minimalist, aluminum hubs with steel bearings. The Sapim CX-Ray spokes feature a custom, bladed section that’s a bit shorter than the standard version’s bladed portion in order to fit the Flo fairings. Flo also offers ‘Clydesdale’ builds for all of its products, with the rear wheels sporting 28 spokes in a three-cross pattern instead of the standard version’s 24 spokes in a two-cross pattern. This allows for a rider weight limit of 242 pounds instead of 198 for the standard, while the front wheel maintains the same 20 spokes in a radial pattern. The 60 wheels come with quick releases, rim strips and a two-year warranty that covers manufacturer’s defects. Flo also makes a 90mm wheelset for $898 and a rear disc for $599. And like the 60 model, these wheels also feature the same proprietary aerodynamic design and co-molded construction in a clincher setup. A low-cost, 30mm clincher is also currently in development. Also, Flo offers a $100 upgrade to ceramic bearings for all of its wheels, with proceeds benefitting the company’s ‘Bike for a Kid’ charity that donates Huffy bikes and Bell helmets to children in low-income neighborhoods.


THE RIDE
Braking

Interestingly, unlike most of its competitors, Flo does not supply brake pads with its wheels. This is largely due to Flo’s attempts to keep costs to a minimum. But Jon also says, ‘This simplifies the installation process for most people, because a standard rubber pad is all you need. We wanted our customers to enjoy the peace of mind that comes with the familiarity of an aluminum braking surface.’ We tested a variety of rubber pads with our 60 wheels, and all of them provided efficient stopping power and modulation on par with most competing aluminum rims. One complaint, however, is that the black anodization that gives the wheels such a sleek appearance began fading after only a handful of rides. After around 200 miles, the black coating had completely disappeared.

Windy conditions
As we’ve been continually experiencing with wider-profile rims over the past few years, the Flo 60 performed very well in strong crosswinds, relative to similarly deep alternatives with traditional V-shaped profiles. Flo’s data from the A2 wind tunnel indicates that a round, bulbous, leading edge on the back half of the wheel mirrors the shape of a tire on the leading edge of the front half of the wheel, thus creating a balanced aerodynamic system that provides predictable handling. One of our test riders used the Flo 60s in a local, 20-kilometer time trial, and here’s what he had to say: ‘Once you muscle these wheels up to speed, crosswinds are quickly forgotten because of their smoothness and aerodynamics. I finished 1 minute, 32 seconds faster than my previous run two weeks prior in similar conditions on different wheels.’

Stiffness

The carbon fairings add weight to the wheels and provide little, if any, structural support, so the wheels’ stiffness falls on the shoulders of the rim itself. Simply put, the 60’s lateral stiffness may be about the same as comparable aluminum rims, but the added weight of the fairing makes for a cumbersome feel during initial accelerations. There’s none of the snap we’ve come to associate with many carbon tubulars or even some deep, full-carbon clincher rims, so it takes quite a few pedal strokes to get the 60s moving. But once up to speed, these wheels simply fly, and it becomes evident that they were designed for maintaining speed rather than initiating it.

Road comfort

Just like its stiffness, the 60’s road comfort is a direct result of its comolded design. The aluminum rim is as vertically compliant as we’ve come to expect from standard-box aluminum alternatives. This gives the 60s a much more comfortable ride quality than full carbon rims of similar depth, all with comparable and, in some cases, even greater aerodynamic efficiency.

Climbing

At 2145 grams total for the wheels and quick releases, the Flo 60s are on the heavy side. While their low-cost, aerodynamic chops and aluminum brake track make them an incredibly attractive option for most riders, those with limited budgets but affinities for going uphill will find more suitable options elsewhere.

THE VERDICT
We’re very impressed with the Flo 60 wheels. Newcomers Jon and Chris Thornham have come out swinging with a unique business model and an even more unique product. The wheels feature an advanced aerodynamic profile and a relatively good ride quality, all at an incredibly cheap price point. Yes, they’re lacking in the quick-acceleration department and they’re not ideal for mountainous rides, but these wheels were designed for speed, and so we recommend them, especially for time trials, triathlons and for anyone living in flat areas who want to go fast. Flo’s first run of pre-orders in February, May and November of 2012, as well as February of 2013, sold out within a few hours, with each pre-order including around 750 wheels. Customers who were lucky enough to snag a set received them between 60 and 90 days after ordering.

With an obvious demand for their products, we asked the Thornham brothers whether or not they plan on stocking wheels at their Las Vegas headquarters. ‘We will when our production can keep up with demand,’ Jon said. ‘We’re a pre-order company now, so everything’s on a first-come, first-serve basis, and we simply can’t make them fast enough.’ Look for more pre-order opportunities from Flo beginning in late spring 2013.

FLO 45 Carbon Clinchers review

The newest wheel in the FLO collection, the FLO 45 Carbon Clincher is designed as an all-around aero wheel for racing and daily rides.

Two features make the FLO 45s one of the most attractive sets of carbon clincher wheels currently in production: price and aerodynamics.

Selling for $1,149 for the pair and with a huge body of research behind the rim’s design, FLO wheels appear almost too good to be true.

FLO 45 Carbon Clinchers highlights

  • 690g front w/ rim strip
  • 860g rear w/ rim strip
  • 110g skewers
  • Tubeless compatible

High performance, low price

The Thornham brothers, Jon and Chris, are the founders and owners of FLO and they prioritized value when designing their wheels.

At $549 for the front and $599 for the rear carbon clincher, there are few other carbon clincher wheels on the market and certainly none that perform like the FLO 45s.

Boyd Cycling, out of South Carolina, come close with a pair of carbon clincher 44mm at $1,500 a pair. Psimet’s C550 wheelset runs $1,179 for the pair.

There are two main reasons for the low price. One, the Thornham brothers sell direct via their website. And two, they sell in batches of 500-600 wheels.

Right now the company estimates that the next order will go live sometime this month. You can sign up for an email notification that will alert you a week before the sale and then it’s first-come, first-serve once the sale goes live.

Nick Legan

That price is even more attractive when you realize the development involved in the rim shape (see next section).

The wheels use premium Sapim CX-Ray aero spokes. Hubs are FLO’s own Vortex 2 design with an aluminum freehub body and Japanese stainless steel bearings, a nice touch that should offer longer life than less expensive bearings.

For best aerodynamics, FLO recommends Continental GP4000s II tires in a 23mm width

While the FLO 45s are tubeless compatible they do not arrive with tubeless rim strips or valves. (I found Silca’s 60mm tubeless valves to be a perfect length for the FLO rim.)

They do come with a set of standard clincher rim strips, brake pads, titanium quick releases skewers and a cassette spacer for use with a 10-speed cassette. 

Tires mounted easily to the 24mm wide rims. The internal width for the 45.5mm deep rim is 17mm. While not the widest on offer, this width does play nicely with both 23 and 25mm tires.

For best aerodynamics, FLO recommends Continental GP4000s II tires in a 23mm width. I used a set of Michelin’s new Power Competition tires for all of my test rides.

Aerodynamics

FLO’s first stab at wheels was based on the belief that the majority of the time a rider is encountering wind yaw angles in the range of 10 to 20 degrees. That is to say that much of the time we experience a crosswind.

As with many things in cycling, talking to different bike and wheel companies results in different answers as to what yaw range bikes and wheels should be designed for.

While happy with the first collection of wheels, FLO knew there was room to improve.

For its new line of wheels, FLO first went about testing assumptions regarding wind angles. As triathletes, their primary interest was the conditions experienced on four popular Ironman courses.

Over the course of 15 months, the brothers collected data using what is essentially a mobile weather station mounted to the front of a bicycle. They recorded relative velocity and wind yaw angle and used video to help contextualize data with what was experienced on the road.

After collecting 110,000 measurements (55,000 readings of relative speed and yaw), their findings showed that much of the time, riders are experiencing much lower yaw angles than their previous assumption of 10–20 degrees. In fact, FLO claims that 80 percent of the time cyclists experience between zero and 10 degrees of yaw.

Nick Legan

Based on these findings, the Thornhams designed new rim profiles using three-dimensional modeling and computational fluid dynamics (CFD).

To help in the virtual modeling, the pair actually cast Continental’s GP4000s II tire so that its shape would be hyper accurate. The environment they build in CFD was based on its vast data collection.

Each rim depth ended up with its own profile and the new FLO 45 is faster than the previous generation FLO 90

Instead of using best guesses at rim shape and putting them through CFD, the brothers created an optimization algorithm that searched for fast rim shapes. This was no small task.

The parameters set for the algorithm included reducing aerodynamic drag, maintaining crosswind stability of the previous generation, maintaining dimensions that would fit inside a bicycle and a list of dimensions for each depth range (e.g. the new FLO 60 could have a depth anywhere from 56 to 65mm).

The Thornhams called in some experts and their supercomputers to help with the computations. Even with the added computational power, it still took two months to complete the calculations.

For the FLO 45 alone, 150 iterations were tested using the algorithm. Then the Thornhams headed to the A2 wind tunnel to verify their findings. While there the brothers also tested 20 different tires to find the aerodynamically fastest models on the new rims.

Each rim depth ended up with its own profile and the new FLO 45 is faster than the previous generation FLO 90, the Thornhams said.

On the road

It’s clear that the brothers put in an incredible amount of work when designing their new wheels.

On the road, I have to say, the FLO 45s deliver. They are very stable at high and low speeds, and in all the breezy wind conditions that Colorado’s Front Range could throw at them.

I used them on quick group rides, solo climbing days and gusty descents, and they never scared me like some other wheels have in the past.

Braking was excellent on the FLO wheels when using the included brake pads. I experienced very consistent, powerful braking throughout my time and no squealing on the FLOs.

This is a far cry from some early carbon clinchers, but it must be said that all the top players have this figured out as well.

Nick Legan

There is a downside, but it’s a minuscule one. The valve stems can tick against the valve hole in the rim. This was remedied with a piece of electrical tape.

I also like the custom decal options. It’s a small thing, but a way to personalize and coordinate your wheels with your bike is pretty nifty. Buy a new bike? Get some new decals to match.

Our policy is to have the most open and honest testing protocol we can

They also felt fast. That’s vague, I know. I’ve most recently ridden Bontrager Aeolus 5s and I would say that the FLO wheels ride similarly. That’s high praise in my book.

Of course all of this is anecdotal, much like any review. I wasn’t able to send the wheels to a wind tunnel to see how they match up to the competition and in a way it doesn’t matter. Why? Well, for a couple reasons.

Unless you do a huge amount of research about the particular conditions you most often ride in and match that up against a wheel’s specific claims, then buying what is “fastest” is essentially a leap of faith.

Each manufacturer designs to different criteria, so there are multiple “fastest” wheels in the world concurrently. The qualifiers (yaw angles, velocity, tested in a bike or alone) necessary to make that “fastest” statement are perhaps more important than whether a given wheel is faster than another. 

FLO doesn’t make claims about its wheels in relation to its competition. Instead the Thornham brothers focus on communicating their methods, putting them into real world terms and let their work speak for itself.

“Our policy is to have the most open and honest testing protocol we can,” Jon Thornham said. “That way people understand what we are doing and what they are getting.”

FLO wheels vs. Zipp wheels

If the FLO wheels are 90 percent as fast as a pair of Enve or Zipp wheels, but they cost less than half as much, do you care? That 90 percent isn’t a measured statistic — just a theoretical question.

What is certainly faster over the course of a race season though is having two pairs of wheels that allow you to optimize your bike for varying conditions and courses.

For example a rear Zipp 303 Firecrest carbon clincher wheel retails for $1,150, exactly the same as a pair of FLO 45s, 60s, or 90s. At 45 millimeters deep the Zipp 303 is within a millimeter of the FLO’s 45.5mm rim.

The FLO 45s are even a tad lighter than the Zipps at 1,550 grams versus 1,625 grams. But at that price, you could also conceivably purchase a pair of FLO’s 60mm wheels for time trials or flat road races. Going a step further, you can buy wheels individually, so consider a 90 rear and a 60 front. You get the point.
