The British, former member of the Ineos group and four-time winner of the Grande Boucle, detailed the gear he will be using during his first season at Israel Start Up Nation. Equipped with disc brakes, his Factor Ostro VAM has something to envy, However, Chris Froome was critical on one point. Indeed, according to him, the technology used for disc braking is not yet effective enough to offer any real benefit on the road. “I am not 100% convinced”, he confides. “The downside of disc brakes : constant friction, mechanical potential, overheating, the discs becoming a little warped on descents of more than five or 10 constant braking minutes. Personally, i don't think technology is quite where it needs to be for road cycling. The distance between the disc and the rotors is still too narrow, so you are going to have this friction, you are going to have a piston that trips more than another, you are going to have these little problems. I don't think the pistons retract quite the way they should all the time. Very often, it will work on the stand and when the mechanic fixes the problem, but once you're on the road, This is an other story”. An opinion that contrasts with the discourse of the manufacturers, who keep praising the merits of these famous disc brakes.
