They have more power that isn't an issue but the mythical modulation.. Is rubbish ITs marking bullshit.
I think you have it backwards. They don't necessarily provide more power; everyone agrees they can lock a wheel with any brake. It's the delivery of the power. But which road disc brakes were you using that did not provide superior modulation? (Have you ridden /any/ bike with disc brakes?)
And FYI they won't make you faster in corners.. 'Carrying more speed longer through corners' that's a matter of skills, balls, tires and pressure. Things disks won't bring to the table.
Yeah, that's why I was reporting that this was the alleged value, not something I can attest first-hand. Certainly I feel a lot more confident descending on disc brakes, but I'm not a good enough descender to comment on whether I can shave seconds off a downhill, so I was just taking for granted these claims by the numerous folks in the industry reviewing disc-brake setups. Not saying they are all going to be unbiased [or even original], but it's a claim being made by folks that at least pretend to know what they're talking about.
They make sense on a commuter bike or poor weather training machine but you sum this up your self with the statement ' I am not a road racer....'
Just because I'm not a road racer doesn't mean I don't ride road bikes -- or even race them on occasion. The idea that one can't comment on road bikes if you don't race is a little daft; most people that own road bikes don't race them.
But I am curious, since obviously you are a road racer, what is the thing that makes you *not* want disc brakes? I mean, assuming all things are equal and you don't have a stockpile of rim-brake wheels and frames. (After all, this discussion isn't about whether to force everyone to convert to discs, but simply the idea that they should be allowed in races.) I have never heard anyone say how much they prefer how rim-brakes stop the bike. Disc brakes do add a little weight. But I assume that's not a problem for racers, because the UCI weight limit is still plenty high to have a disc-brake build. They arguably make the bike a little less aero. Maybe that's the real objection? Or is it heel clearance with wider rear hub spacing? But seriously, trying to salvage something constructive here, why wouldn't you, as a road racer, choose a disc-brake bike if you were starting from scratch [and they were legal]?
1 point worth considering.. Every single racing machine worth a mention in the world right now using disk brakes has suspension... Some thing I don't want on my 5kg roadie
One other point worth considering -- obviously ignoring CX bikes -- I suspect maybe the reason you're not seeing more disc-brake road racing bikes is because THEY'RE NOT UCI LEGAL. Hence the thread title. Just a hunch, though.
