Slippery speed.

Factor Bikes' sole purpose is to build the fastest racing bicycles on the road, regardless of which continent those roads are on. We're such strong believers in Factor's work that we began with the 2018 Factor ONE frameset ($5,499 MSRP) and built it up with a curated selection of some of our favorite finishing kit. Rather than a stock build from Factor, the ONE SRAM Etap Complete Road Bike is an in-house build reflecting the stuff that we actually race on at Competitive Cyclist, and it's everything a racer could ask for from the roads around our office in Park City, UT, to the roads of Western Europe, where AG2R is racing a similar build.

For this build, we took the ONE's excellent chassis and added a carefully curated kit to help extract as much speed as possible while coming in at a surprising price point considering the ONE's dream bike status. SRAM's wireless electronic shifting with Cane Creek's direct-mount eeBrakes and an integrated cockpit combine with Mavic's Cosmic Carbone wheels for an all-out assault against the wind, climbs, and the peloton. The proof for that final claim is in the practice: we've spotted the new ONE frame under current Belgian national champion and AG2R La Mondiale pro Oliver Naesen as he campaigns the early season classics.

The northern classics are notorious for being difficult, both on riders and equipment. For success, a lightweight frame is essential for scaling the bergs and muurs and responding to consistent attacks. Next up, a responsive frame is required for quick maneuvers around traffic furniture, fallen riders, and the ability to confidently handle a descent so as to not give back any hard-earned seconds gained on the short, punchy climbs. And when it's time to roll in that breakaway, an aero edge that allows you to squirrel away any watts for a late attack can pay heavy dividends. Oh yeah, there's also the fact that the frame has to handle repeated cobble beatings while supplying some comfort during the 6-hour slugfest.

The ONE is able to achieve all of these characteristics due in most part by its collaboration between some big names in the cycling industry and a big name in automotive aerodynamics. The project was originally started by bf1systems, a motorsport firm that dabbled in cycling with the revolutionary (and non-race-legal) Factor 001 and Vis Vires framesets. A group of two-wheeled visionaries recognized the potential of bf1systems' designs, snapped up the Factor name and technology up, and have since translated it into race-legal framesets with the ultimate aim of sponsoring a World Tour team.

The ONE's aerodynamic benefits are of course the frame's strong suit and features are apparent to the naked eye. The vertically oriented tubes' bullet-nose face and truncated trailing edge will be no surprise to anyone staying abreast of industry advances because the shape babysits airflow from the point the frame encounters it till long after it's detached and dissipated into the wake. The abbreviated rear face is especially important for two reasons. First, it reduces the negative vacuum of trailing drag that traditional NACA tube shapes produce. Second, it doesn't turn into a destabilizing parachute when crosswinds and road conditions shift the yaw angle outside of a NACA profile's near-zero comfort zone.

Then there's obviously the One Total Integration System (OTIS) front end. OTIS enjoys the benefits of presenting a minimal face to the wind (it's practically two-dimensional head-on) and—with the inclusion of an external fairing that rotates with the fork and bars, it disturbs the air as little as possible. These features are designed to work in cahoots with the bifurcated downtube in order to take full advantage of the peculiar design, and without both elements, the significant claims of reduction in air resistance are void. The OTIS's integrated Evo bar/stem combo also does its part, increasing stiffness, boosting the frame's aerodynamic benefits yet further, and actually managing to reduce frontal surface area when compared to the Vis Vires.

The frame's aerodynamic features extend to such subtleties as a hidden seatpost clamp, wide-stance seatstays, internal cable routing (for electronic drivetrains only), and the inclusion of the aero OTIS Evo integrated stem/bar unit designed to work as part of a drag-reduction system with frame and rider. And even though these wind-cheating features are typical of an out and out high-end aerodynamic road frames, given that Naesen chooses this set up even though he has access to the brand's O2, proves that it's also an excellent all-arounder.

The fact that the aerodynamics don't come at the cost of comfort is a surprise, though. While the ONE isn't as buttery smooth as a classic, lugged steel frame it does transmit a lot less harshness than the non-traditional tube shapes and seatpost would suggest. We feel this is in most part to do with the EM2 RGi carbon lay-up. Given that one of Factor's co-owners has a 15+ year pedigree producing carbon frames for an impressive list of boutique brands, we suspect the latter might play a significant role. The ONE's EM2 RGicarbon construction involves three different carbon moduli that balance the vibration damping and durable compliance of lower and middle moduli with the unyielding stiffness of Pitch Fibre, a material that is as unabashedly stiff and light as its name are unabashedly British.

Factor isn't shy about claiming that Pitch Fibre is the lightest, stiffest material that can be shaped into a bike frame, so you might assume three things here: 1) Pitch Fibre is extremely difficult to work with, 2) it's very expensive, and 3) Factor jealously guards the exact details of its lay-up schedule. You'd be correct on all counts. The one insight Factor gives into its process is the use of a program called Fibersim, which Factor uses to "ensure that we put the waste into the garbage can and not into the frame." Fibersim helps the brand keep material to a minimum, resulting in fabric cuts and construction so discerningly meticulous that the process rates at the tippy-top end of luxury, a theme that's also reflected in finishing details like a Ceramic Speed bottom bracket.

Finally, though Factor typically builds its bikes with AG2R-sponsor Shimano drivetrains, we've taken the opportunity to paint this canvas with a wide swathe of SRAM Red eTap. This includes the wireless functionality mentioned above, and pairs it with the oh so light yet very powerful eeBrakes Direct Mount calipers. SRAM did just release its first Direct Mount brakes, however, it isn't under the Red group designation so it doesn't receive quite the material and performance treatment we felt represented the rest of the build. Mavic's Cosmic Carbon wheels are another nod to all-around versatility, as the rim aerodynamics work with the frame's aero shapes to provide a sustainable advantage in every scenario except the steepest of climbs.

Setting PRs

  • Familiarity: I've used it several times

This bike is fast. Like really fast. It climbs fast and is very aero. The split down tube is weird, but noticeably stiff. And the color is on point too!

A couple specific notes:

The head tube is not traditional. The steer tube moves around the head tube. The system is stiff but a little intimidating to work on.

Water will come through the split down tube.

The saddle clamp is pretty annoying but effective when you get it set.

The bike is really fast and if performance is the most important thing to you, buy this bike

Aero and it Climbs

  • Familiarity: I've used it once or twice and have initial impressions

Having the unique opportunity to ride a majority of the top end bikes we carry allows us as Gearheads to be very particular or shall we say critical about each bike and every bike. Keeping that in mind there really isn’t a bad bike in the line up it’s simply that another might do something better.

The Factor ONE is a really lightweight aero bike with great looks and one of the coolest down tube frame designs on the market. Myself I would consider a descent enough road racer with a better than average sprint, so for me I want something that puts power to the ground, corners well and gets me to the finish. This bike does all of that except the cornering part. It is simply a bit to nervous in that regard. You want to sit on the top tube and descend at 45-50 mph this is not the bike for you. You want to solo away on a break and hit the climb at the end this is the bike for you.

One of the coolest features is the handlebar steer tube set up. It allows you to move the stack height up and down without cutting the steer tube. Want to run it slammed for the races perfect. Got a century coming up and need some more comfort add some spacers.

Does anyone know the standover height for a size 56 Factor One (or 02) frame.

Hi David, I just measured the 56 O2 bike we have on the floor. It has some rather plump 28C tires and standover looks to be at 800mm measuring straight up from the ground through the BB.

The best road bike I've ever ridden

  • Familiarity: I've put it through the wringer

Yes, I know. That is a very broad, all-encompassing statement. I don't hesitate to say it though. I don't remember the last time a bike floored me the way that this one did. My five-second-summary is as follows: This is the aero bike I'd be happy to take (and did take) over a high mountain pass. It's incredibly light, handles like a dream, and its rock solid on high-speed flats.

The ONE will most likely be cross-shopped with the likes of the Pinarello Dogma F10, Bianchi Oltre XR4, and the Wilier Cento10. Price-wise, the frameset comes in at about $500 less than the Dogma, and roughly a grand more than the others. It's worth mentioning though, that the frameset comes with a Black Inc. unified bar/stem, Black Inc. seatpost, ceramicspeed bottom bracket, and ceramicspeed headset. Once you take that into consideration, the price-point is actually pretty aggressive. You can't ride on value at this price point though, and the ONE certainly doesn't. I can tell you in a heartbeat that I would take the ONE over any of those bikes even if price wasn't a factor (no pun intended.)

The ONE's split downtube helps it post incredible numbers in the wind tunnel, but on the road, it also contributes to rock solid stability. I took the ONE for a loop around Park City, climbing over the Olympic Park, Royal Street, and Empire Pass (if you're make it to Park City, you've got to try that route out). Those 3 climbs are laced together by open, relatively flat roads, and they allowed me to get a good taste of the ONE's road manners on it's home turf. This bike is seriously fast, even with relatively shallow (40mm) Mavic Cosmic Pro Carbon UST wheels. On the same loop it felt far more confident in the crosswinds than a Dogma F10 with ENVE 3.4s. I'd also put it in the same class as the Dogma in terms of handling. The ONE was stupid fun to ride. Twisting down the switchbacks of Royal street and Empire, the bike inspired an incredible amount of confidence. it's perfectly predictable, and wonderfully stable.

The ONE really shocked me on the climb. Empire Pass is a beast. GCN ranks it in the top ten climbs in the US ( It'snot the kind of climb where you'd generally reach for an aero bike. The ONE, built up with Mavic Cosmic Pro Carbon wheels, eTap, and a Black Inc. cockpit in size 54 comes in at about 16lbs, but it feels lighter. It absolutely crushed Empire. Yes, the ONE's lighter cousin, the O2, probably would have done better, but the experience really cemented my view of the bike. The ONE is fast everywhere. It doesn't know how to go slow.

This particular build was also extremely impressive. The two main call-outs I'd give would be for the brakes and the drivetrain. I can't overstate how good Cane Creek's eeBrakes are. I get that not everyone is ready to jump to discs yet, but ride eeBrakes at very least. They're absolutely the next best thing. Mated with Mavic's excellent exalith brake track, they provided immediate power, and wonderful modulation. SRAM's eTap drivetrain is a standout as well. I honestly can't recommend anything else. I reviwed the eTap drivetrain in detail a couple of months back, so feel free to read over my thoughts (link below). The value for this package is remarkable. A zero-compromise build like this, for $8750? Honestly, if I paid $10k for this build, I'd be more than happy. Feel free to get in touch with me directly at if you'd like to talk through the bike in more detail!

Superbike for a Reason

  • Familiarity: I've used it several times

I've had the chance to ride a number of bikes from the 2018 Road Bike Buyers Guide (see here: and I have to say the One takes the cake. The R&D Factor put into this bike truly shows. I found it to have a surprising balance of speed, comfort, and handling - not something you see too often in an aero bike.

I'd like to call out a few key components on this build.
1.) The Cane Creek eeBrakes. I'd never used them until now, but were I to build up a rim-brake bike I wouldn't chose any other brakeset. These vise grips are the closest I've come to disc brake stopping power. I felt completely comfortable descending one of our local canyons on the Mavic carbon brake track, which could not be said for the SRAM Red brakes I've previously used with Cosmic Carbon 40s.
2.) SRAM Red eTAP. Others may disagree, but I feel this is the king of groupsets right now. Incredibly intuitive, simple to setup and has just enough of a delay that you retain the mechanical feel of older derailleurs. If you're building your dream bike, I would not settle for less.

With the crimson colorway the bike glistens in the sun and you absolutely have to go fast if you're rockin' this color. You will have heads turning when riding this bike.

I have plenty of ideas on how we could make this your dream bike. Give me a call or shoot me an email if you're looking for the One.

Can you change configuration such as changing crankset 53-39 and medium cage derailleur?

We offer this bike as a package, so you are indeed able to swap compatible parts, change gearing, etc.

If you're interested, you can send me an email directly to discuss build options! I'm at

What’s the weight of this bad boy in a 56cm?

Hey Patrick,

Don't have access to the numbers for the 56cm, but a 54cm with Look Keo pedals and a bottle cage weighs in at 16lbs.
