So what difference do discs make to a racing bike (not a beater, or training bike, a race bike)
Oh yeah, profit margin, i forgot.
Well, certainly profit margin is driving this but there is a valid argument at the core. I am not a road racer, but the argument for disc brakes is that you can brake later in turns -- carrying more speed for longer. Thanks to better modulation and consistency.
I love my disc brake road bike. I certainly am convinced this is better braking. Especially with carbon rims (which seems like the only valid comparison when talking about road racing).
They have more power that isn't an issue but the mythical modulation.. Is rubbish ITs marking bullshit.
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.
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....'
One day they will be the way but banging a set of Mtb hydros on a roady and proclaiming the future is not the way forward.. There are so many different factors that need to be considered to make 'road disks' truly workable and to bring in real world performance gains.. 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
