Ventoso blasts the use of disc brakes in the peloton

'Nobody thought they were dangerous? Nobody realized they can... become giant knives?'

Francisco Ventoso's (Movistar) is recovering from deep wound to his leg caused by a disc brake during a crash at Paris-Roubaix on Sunday. Three days later, the Movistar rider has penned an open letter blasting the pro cycling community including international and national governing bodies, teams and riders for not taking action to prevent the use of disc brakes in the peloton.

"Shortly afterwards [after the crash], I have a glance at that leg: it doesn't hurt, there's not a lot of blood covering it, but I can clearly see part of the periosteum, the membrane or surface that covers my tibia," Ventoso wrote. "I get off my bike, throw myself against the right-hand side of the road over the grass, cover my face with my hands in shock and disbelief, start to feel sick... I could only wait for my team car and the ambulance, while a lot of things come through my mind."

I've always wondered about a crash and hitting my spinning front wheel
disk. Even more I wondered why they don't make them 0.050" or 1mm larger
in diameter and then round off the outside. But I guess the answer is
the usual, "weight weenieism".

Discs can become dangerous but they sure can stop you on a dime. Maybe
that is why he rear-ended the cyclist in front of him, the guy had disc
stopping power and Ventoso didn't.

By gorry this bicycle riding seems like a dangerous pastime. Given the
impossibility of repairing bike brakes as evidence by one of our
correspondents and now the evidence of the dangers of another type of
brake perhaps it would be better to just ban brakes from being
installed on bicycles.

Fixies For Ever!

Surely that's impossible if he was wearing his helmet?

Undoubtedly you are correct. The above reference certainly shows the
wounded "moviestar" not wearing a helmet.

The mechanism of the injury isn't really clear. He would have munged his leg in the spokes in any event, but the spinning disc apparently created a new hazard.

I like road discs for my non-racing rain bike and commuter because they stop much better in wet conditions and don't grind down my rims. I would bother with them on a mostly dry-weather racing bike -- but in the PR they might serve some purpose by allowing the use of a frame with more clearance and room for larger tires, e.g. the latest Domane or any of the gravel bikes. They also stop well, but so do rim brakes -- at least on an ordinary racing bike with the right pads.

this injury is not commonly accessed. knda hard getting your shin in there but you know accidents...

easier accessing Ventoso

That makes sense to me.

I tend to get irritated by the "safety inflation" aspect of these bike
tech developments. We've been through the argument that it's "unsafe"
to have to move your hands from your brake levers to shift gears. I was
once told in this forum that my pedals were unsafe because they were
more than 10 years old. As soon as certain people see or imagine a tiny
safety benefit, they think it should be (almost?) mandatory.

We'll doubtlessly be hearing that non-disc brakes aren't sufficiently
safe because they don't stop quickly enough in all conditions. It's
sort of nice to see some hand-wringing about lacerations, just to
balance things out.

Disc brakes also shine when taking the occasional dirt path in any kind
of weather. My road bike unfortunately has rim brakes (it's 30+ years
old) and braking after a dirt stretch often gives me the goose bumps ...
KRCCHHHHH ... you can literally hear them eat a layer off of the rims.

It's been so long since I've raced that it never even occurred to me to consider a disk as a weapon. But they are the only thing to ride on very steep descents. But perhaps he is correct and these could either in come manner be shielded or removed from the peloton.
