/ Immediate Media

Marcel Kittel has won stages 2, 6, 7 and 10 of the Tour de France aboard a Specialized S-Works Venge ViAS Disc. In winning stage 2, Kittel became the first rider in history to win a stage of a grand tour on a road bike with disc brakes.

Historic first: A double-disc Tour de France time trial bike Tour de France bikes, gear and tech Spotted: Giant Propel Disc prototype at the Tour de France Kittel’s wins follow a spate of controversies and marks a key moment in the use of disc brakes in the professional peloton.

Disc brakes came into the World Tour peloton on a trial basis at the beginning of the 2016 season. But following the injury at Paris-Roubaix of Movistar rider Fran Ventoso that was allegedly caused by a disc, the trial was put on hold until the beginning of the 2017 season.

Tom Boonen (Quick-Step Floors) took the first professional victory on disc brakes at the Vuelta a San Juan this January, and then Kittel won on discs at the Dubai Tour the following month.

Disc at the stage 2 sign on in Dusseldorf Josh Evans / Immediate Media However, following another crash incident in the Dubai Tour involving Team Sky’s Owain Doull, Kittel stopped racing on disc brakes for the remainder of the stage race.

Disc brakes were used prominently throughout the spring classics, but weren’t involved any any big victories. In fact, the main favorites all chose to race on rim-brake bikes. Boonen used a pro-only rim-brake version of the Specialized Roubaix for Paris-Roubaix, his final race.

At this year’s Tour de France, Michael Matthews (Team Sunweb) and Reto Hollenstein (Katusha-Alpecin) also choose to race disc brakes.

rotors Josh Evans / Immediate Media In the Tour’s opening time trial, Cannondale-Drapac’s Alberto Bettiol used a Cannondale Super Slice with disc brakes.

On stage 2, it was reported that Kittel suffered a puncture early on in the stage and whilst the wheel change from his team took slightly longer than normal, it clearly didn’t prevent the German sprinter from taking victory.

Following the stage, Kittel was informed he had made history by winning with disc brakes in the Tour de France.

“I actually wasn’t aware that if I won I would get this title, but I said before that I think that it is a good step forward in technology development that we still have ahead of us,” he said. “There is a lot of discussion around disc brakes, but in the end I was riding today on an improved version from Shimano. They’re definitely better than the old ones (Kittel used non-series Shimano disc brakes earlier in the season). There’s more adjustment possible and that’s a big step forward and from now on I think, especially with the rain today, it will help riders to brake better. The control is good.”

Specialized designer Ron Jones played on the CERN particle accelerator for the bike’s graphic theme Ben Delaney / Immediate Media Kittel also said that rider safety is a good thing.

“I hope that we find with the industry and the UCI, and especially with the riders together that we can get rid of the last negative thoughts about disc brakes, especially when it comes to safety,” he said. “I think there is still support for it and I hope that they approve the request to protect the riders from a potential injury that you could have from a disc in a crash and the whole issue of changing the bike or wheel can be solved. I’m sure that if we can talk in the right way then we can find a solution to it.”

Another issue that needs to be solved is rotor standards, as 140mm and 160mm options are currently used.The UCI has settled on 160mm as its standard, and told Mavic neutral support to supply 160mm rotors at the Tour. But Kittel and Matthews were both on 140mm Shimano rotors. Rollenstein, on a SRAM bike, raced with 160mm.

Take a look at the gallery above for a closer look at Kittel’s Specialized S-Works Venge ViAS Disc, as well as the disc bikes of Matthews and Hollenstein.
