Dream stuff.

Factor Bikes was founded to build nothing but dream bikes. We're such strong believers in that dream that we took the 2018 Factor O2 Disc frameset ($5,049 MSRP) and built it up with a curated selection of some of our favorite component brands. Rather than a stock build from Factor, the O2 Disc SRAM Red eTap HRD Complete Road Bike is an in-house build reflecting the stuff that we actually race on (and dream about) at Competitive Cyclist.

Of course, the dream begins with the O2 itself, and we took that dream-bike inspiration and ran with it, assembling a build kit that—even just a few years ago—was literally the stuff of dreams. SRAM's wireless electronic shifting and road hydraulic disc brakes combined with the latest in Zipp's ever-evolving quiver of speed weaponry simply didn't exist a few years ago. And they're not even the most impressive parts; we reserve that honor for the heart of the dream, the frame itself, which is the same model Bardet rode to a stage win in the 2017 Tour.

During that win, the O2's stiffness was on full display with a final grind up the Peyragudes, a wall so brutal that it produced the only apparent weakness we saw from Froome between Düsseldorf and Paris. What wasn't as obvious is the frame's sub-800g claimed weight, which no doubt contributed to keeping Bardet's fatigue down across the final sucker punch of Port de Bales, Peyresourde, and Peyragudes, ensuring he had enough oomph left in the tank to muscle up the final ramp and overtake Aru for the win. A bike with such a low weight and a deceptively responsive drive spine seems like a too-good-to-be-true fantasy, but Factor manages to bridge the divide while maintaining an admirable amount of long-mile comfort. It's not as smooth as an endurance-minded steel frame, but the O2 doesn't have the ass-on-asphalt punishment so common in the sub-800g, high-mod category.

The O2's characteristics are the product of a collaboration between some big names in the cycling industry and a big name in automotive aerodynamics. The project was 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 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.

Though not as advanced as the One and One-S models, the O2's aerodynamic benefits are still readily apparent to the naked eye. The vertically oriented tubes' bullet-nose face and truncated tailing 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 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.

The frame's aerodynamic features extend to such subtleties as a hidden seatpost clamp, tucked-away seatstays, internal cable routing, a Di2 junction box, and the inclusion of an integrated stem/bar unit designed to work as part of a drag-reduction system with frame and rider. Frankly, we expect this roster of wind-cheating features from high-end aerodynamic road frames; given Factor's penchant for going above and beyond what's expected, it's no surprise that they're all represented here.

The fact that the aerodynamics don't come at the cost of comfort is a surprise, though. We've got to stress again that the O2 isn't as buttery smooth as a classic, lugged steel frame or a heavy, carbon cobbles machine, but it does transmit a lot less harshness than the non-traditional tube shapes and seatpost would suggest. Maybe this is because of the low chainstay juncture and shape, or maybe it has something to do with the EM2 RGicarbon lay-up. Given one 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 O2'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 is 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 it also adds the versatility of SRAM's HRD hydraulic disc brakes. This is a concession to safety and reliability over pure pursuit of low weight. Guys like Bardet don't typically have time for braking on descents—indeed, the Frenchman's star shines brightest during daring downhill raids—but we like the ability to stop on command in all conditions and while descending the kinds of steep climbs where the O2 earns its keep. The Addition of Zipp's 404 NSW wheels is another nod to all-around versatility, as the rim aerodynamics mean the bike is a blast whether you're punching up a climb like the Peryegaurdes or rolling through to the front on a 100-mile out-and-back.

A Solid Foundation

  • Familiarity: I've used it several times

I had been very curious about the Factor brand bikes for a while, but wasn't able to get my hands on one to give it a solid test. The O2 Disc is a bike that really knows how to treat a rider. I didn't find it as quick or nimble as I have many other road bikes in the industry, however it was a great platform. The best comparison I can give it would be that of a Cadillac. It was smooth, comfortable, and really cruised in and out of corners. With many bikes you see in the peloton, you can feel every bump in the road. But with the Factor O2, you sailed the entire time without hesitation. Pairing this bike with a 30c tire really gives it a plush ride, but don't take my word for it. Try one for yourself!

Be Like Bardet

  • Familiarity: I've used it several times

This should definitely be on your list for potential superbikes to buy! The Factor O2 disc is a lightweight, stiff, and compliant ride. The bike climbs and descends just as good as any other superbike. The bike is solid on the climbs and bullet fast on the downhills. No issues climb or sprinting out of the saddle.

My only tiny gripe would be the integrated cockpit. The Black Inc integrated cockpit limits some adjustability. I prefer narrow bars (38cm) and shallow drops. Otherwise, this bike is solid!

Orange Crush!

  • Familiarity: I've put it through the wringer

I have had this bike for a few months now. The only changes I made were a red cassette, a non-set back post and 303 NSW wheels. I got the burnt orange color and it is beautiful. This frame is very stiff laterally but at the same time compliant over rough roads. This bike is an excellent climber and holds speed very well. I have used Shimano Durace components exclusively in the past but have to admit that I really like how the SRAM E-Tap performs as well as the clean wireless look. This is my first disc road bike and it is amazing how much braking control you have on mountain descents. If you are on the fence about this bike, go ahead and take the leap, you will not be disappointed.

Watch out Dogma

  • Familiarity: I've used it several times

The Factor O2 doesn't quite fit in with the usual crop of superbikes.

If you shop around the $10k price range, you'll see a few repeating themes. Bold frame designs, cutting edge tech, whole webpages dedicated to the 500 year history of the brand, etc. Factor is different. They just want to make the best bikes, and the O2 demonstrates this with perfect clarity.

At 750 grams, the O2 is really, really, light. As a fairly large rider I can also tell you that it's incredibly stiff. Its got the 'magic-carpet' ride quality of a well engineered carbon frame, and this build even features SRAM's top end eTap HRD wireless disc groupset and top-of-the-line 404 NSW wheels. Critically though, it's fast. Insanely fast. IThe O2 will provide speed with aplomb anywhere. It'll make you feel like Bardet on the climbs, and Dillier on the cobbles. After riding it for a week, I can say confidently that this is the best all-around superbike you can buy. And yes, the Burnt Orange paint looks as good in person as it does online.

This particular package is unique because we can change anything you want! Feel free to reach out to me at if you have any questions!

Factor 02

    First thing I noticed when I picked this bike up is that it was a bit heavy. Expected really since it is a disc frame and it goes with the territory. Unexpected is that it did not feel heave when climbing, in fact I was quite impressed with it's uphill ability. It will not hold you back. It's stiff enough that standing is super efficient. It's been comfortable over any ride I've done although 55 mi. has been the furthest so far. The bar/stem combo was stiff, felt great to spring with. Etap was great, I lean towards di2 but it's splitting hairs between which is better. Factor 02 is now on my list for possible new bikes.

    Factor 02

    Would I be able to order this bike with a 53/39 crank instead of the 50/34 compact ?

    Hey Scott,

    Yes we can customize builds here in our bike shop to fit your needs. Feel free to contact me directly and I would be happy to get that build set up for you with a 53/39 crankset.

    Thanks, Matt

    Hey Scott!

    We can absolutely swap out the compact crankset on this bike for a 53/39! This particular build is a package that we put together here at Competitive Cyclist, so we can make any customizations that you'd be interested in. Feel free to reach out to me directly at if you have any more questions about customization.


    Pro Level Race Machine

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

    The Factor O2 has amazing power transfer, and is extremely responsive. I am 5'6" but have a longer inseam (31") for my height I rode this bike in a 52cm frame with 30mm of spacers under the stem which felt ideal for me. I got to demo this bike for a week and was reluctant to bring it back. The responsiveness is amazing! These wheels are stiff and offer sharp handling compared to other brands that I have ridden in the past. If I were allowed to keep this bike for a longer period of time I would run 28c tires on it. The clearance was for sure there and I feel like the larger volume tires would have helped on some of the crappy roads I ride regularly. I got out on the bike for 5 separate rides ranging from 1 hour to almost 4 hours. Shifting took some getting used to but was crisp and accurate. The bars were plenty stiff for hard efforts and did not leave me wanting for more adjustment. With some 28's I can confidently say Century rides would be a pleasure, with 25's 3+ hours is no issue, but this bikes true calling is racing and the stiffness and responsiveness of the frame and Zipp 404 NSW wheels really lend to a racing feel.
    Bikes I have recently ridden: SW Tarmac, Madone, Roubaix, Domane, Allez Sprint, TCR, and Defy.

    Does it has an set back seatpost?

    Yes, these are shipping with the set back seatpost

    What kind of pedals would you guys recommend for the Factor 02 bike?

    What ever you used on your previous bike and or best fits your style and limiters (i.e. bum knee, tight hip, etc.)
