Pro Bike Profile: Rebecca Fahringer’s Scott Addict CX Goes Tubeless with Stan’s NoTubes and Maxxis

by Brandon Grant

After a breakout season as the Amy D Foundation's sponsored cyclocross rider last year, Rebecca Fahringer is continuing this year as the manager and pro rider for the Stan’s NoTubes p/b Maxxis cyclocross team. Fahringer rode a Scott last year for the Amy D team and she is continuing to stick with the company's Addict CX with her new program.

Back in September at Jingle Cross, Cyclocross Magazine took a closer look at Fahringer's Scott Addict CX equipped with Stan's NoTubes Valor rims and Maxxis tubeless tires.

The Scott Sports Addict CX was released a few years ago, but the model has been updated with current technology, adding 12mm thru axles front and rear, as well as the flat mount brake standard.

Scott claims the bike is the lightest disc cyclocross platform on the market at less than 1,300 grams for the frame and fork, and Fahringer definitely appreciates the low weight on run-ups and barriers, “The best thing about the Scott Addict is it may be one of lightest frames out there, and add the Carbon Valors and I am getting a lot less fatigued as I need to shoulder my bike. So light," she told Cyclocross Magazine.

Fahringer’s bike runs Shimano 6870 derailleurs, and ST-R785 Di2 shifters, which are new to her for this season. Stopping is handled by Shimano's BR-R785 hydraulic calipers. Interestingly, Fahringer is using post mount calipers, despite her frame being built for flat mount, requiring the use of Shimano adapters to clear her 160mm XT RT81 Ice Tech rotors.

One interesting aspect of Fahringer's setup is the Stan’s NoTubes Valor carbon rims laced to Neo Ultimate hubs. While carbon wheels are common in the pro ranks, tubeless tires are not.

We have seen a few other tubeless setups on pro bikes in the past few years. Mical Dyck ran Stan's NoTubes Valor tubeless rims en route to finishing 16th at 2015 Worlds in Tabor. We also saw tubeless Schwalbe X-One Speeds on Michael van den Ham's bike at CrossVegas this year.

According to Fahringer, NoTubes Pro riders are provided with Valor carbon rims, which means staying sponsor correct requires tubeless tires. Fortunately, team sponsor Maxxis makes a full line of tubeless rubber that fits within the UCI maximum of 33mm when mounted on these rims.

Fahringer says she is seeing more riders choosing tubeless systems. "The major issue that anyone will argue about tubeless is you can't run the pressure as low as with a tubular," she said. "I have gone to 19 psi, I am 145-150 lbs, on even hard-packed, fast courses where one might have more concern about burping a tubeless or rolling a tubular and have had no issues."

Fahringer continued, "At that pressure I start to feel my sidewalls have some give and slide, and personally, I don't like that feeling on any tire, tubed or tubeless, so even on tubulars I don't like running under 19 psi. The low pressure argument never slides with me."

She also added that going tubeless allows her to own fewer wheels, which she sees as a huge advantage over tubular tires.

We also looked at the bike of Katherine Santos, who rides for the Amy D Foundation development team. Amy D is managed and supported by Stan’s NoTubes, so much of the bike is the same. The biggest difference is Amy D riders are supplied aluminum Grail wheels rather than the carbon Valors found on NoTubes team bikes.

Santos also opts for a Cobb DRT Plus mountain bike saddle. This saddle was developed for long distance off-road riding and features hollow CrnTi rails, waterproofed stitching, and a kevlar rear cover.
