Just not a fan of needless complexity or solutions that didn’t have a problem to solve (for me).
I disagree, road bike brakes seem to need a tweek every so often as cable stretches, pads wear, etc, especialy for some reason my back one which seems to drift round untill one pad rubs.
My disks on the other hand take longer to fix, but even my elixirs haven’t been touched in a year (at all, no adjustments, pads, nothing).
I had no luck whatsoever trying to race on a disc-braked road bike. Even though races don’t have to stick to UCI rules, they seem to just follow them anyway.
I can see why, some UCI rules are there for good reason, even if they’re not imediately obvious. Like mudguards, seem like a great idea on a wet day, untill someones jam and cause everyone to crash. If they allow one concession (disk brakes) the next week someone will want mdguards, then someone will turn up on a TT, bike, then a Tri bike, then a recumbant. Easier just to stick with what the UCI defines as ‘a bike’.
