This whole disc brake versus rim brake in the peloton safety issue has now got even more ridiculous with Astana demonstrating that you’ll suffer no injuries if you stop a wheel by putting your hand on the tyre… as if anyone thought that you would!
This is a riposte to the Team Katusha Alpecin’s communications manager Philippe Maertens showing on Twitter yesterday that you can stop a fast-spinning disc brake rotor by putting your hand on it gently – which everyone with even a vague interest in the subject knew already, didn’t they?
Astana Proteam said on Twitter, somewhat sarcastically: “@philmaertens Experiment of the year! Are the rim brakes so dangerous? Let’s try!”

As we reported nearly a year ago, Movistar’s Fran Ventoso claimed that he was injured by a disc brake rotor in the 2016 Paris-Roubaix race, and Team Sky’s Owain Doull recently said that a disc brake rotor “cut straight though” his shoe.
However, the World Federation of the Sporting Goods Industry (WFSGI) commissioned a report into the Ventoso incident that involved an accident reconstruction. Its ‘expert’s report’, dated 12 May 2016, concluded that Ventoso’s injuries could not have been caused by a disc brake rotor.
The debate between the WFSGI, the UCI and the CPS (Cyclistes Professionnel Associés, the organisation that represents professional cyclists and is often termed the 'riders' union’, centres on whether or not the introduction of disc brakes in their current form creates a new hazard for riders over and above those that already exist.
The CPA has said that it is very concerned that the disc brake trial has resumed “before some appropriate test were conducted on the risks to which the riders are exposed in the event of accidental contact with the discs.”
Have the Katusha Alpecin and Astana Twitter videos moved that debate forward? You decide!
A year into this debate, how about the UCI undertakes a series of accident reconstructions with bikes fitted with rim brakes and with bikes fitted with disc brakes, maybe a worst case scenario, using forces associated with crashing? Then we can have some actual facts and everyone can calm down. Just an idea!
