Disc brakes on road bikes

[BSRU]

I wonder why they allow them on racing motorcycles then, which can go barrelling down the road at 200 mph? Nobody ever wanted chainrings banned on bikes because the teeth might slice someone's leg off.

In general the crashes in motorbike races are different to crashes in bicycle racing.
Also with chain rings you tend not to keep peddling when your about to crash into someone and normally the big ring teeth have a chain on them.

The story about riders being injured by discs in a crash is twaddle. Mountain bikers crash a hell of a lot more than roadies and I've never heard of anyone being injured by a spinning disc. I've heard of people burning themselves and stupidly sticking a finger in a disc but never being hurt by one in a crash.

I only made that mistake once! (I branded my leg with a hot rotor after a big descent.)

Yeah, they happen at higher speeds and the whole bike often ends up on top of the rider.

I have the synapse disc. Last weekend went for a 30mile ride around Devon back lanes, very gloopy, grit and not good for rims. The discs are so cheap to replace i really dont care about the crud.

Earlier this year went on my first tour on a new Dawes Ultra Galaxy with Shimano discs, about 500 miles. First time i have ever used a bike with discs. They were set up by the LBS before I left.

I hate them.

I spend a large part of the trip f*rting and faffing about trying to get them to work properly. Every downhill I was well and truly juddered.

I really don't know why I just didn't by another Super Galaxy with perfectly good cantilever brakes and saved myself a load of money.

Would it be possible to fit disk brakes on a road bike that has conventional brakes? If so would it be expensive and difficult?

You could just have them at the front by fitting a disc compatible fork.

Ive been riding a couple of road bikes with discs for a number of years, a steel forked Croix de Fer and a carbon forked Landescape tandem. Neither with front suspension. Both are very comfortable indeed. Both have Avid BB7's which so long as they are set up right in the first place have been trouble free and require very little in the way of ongoing adjustment and way, way less than cantilevers..

Couldn't get a replacement disc once, had to buy a complete brake? Anyone want disc brake without a disc?

What's to set up? Never ever set up anything they just work.
Discs are an investment they save you money in the long run. I wore 4 rims out on one bike rear only as the front was disc. Even pads work out cheaper.
I am of course ignoring the bike with ceramic rims.

PS Rolhoff gears are also an investment which will save you money, although in this case you have to put the miles in to save on chains and sprockets. As I had habit of breaking derailleurs I have saved more money there as well.

I went over to discs on mountain bikes about 15 years ago after suffering years of the wear and tear of Lancashire grit on rims - I got pretty good at fitting new rims to my wheels by taping the new alongside the old and transferring the spokes over. Then I bought a disc-brake Global Ti and had to find some wheels, bought a set second hand and have been using them ever since, the rims are in perfect condition. Still got the original Hope minis as well and they work as well as they day they were new.

I rarely if ever lock the wheels on my car and haven't done for years.

Cars have had anti-lock brakes for years.

Nothing I've ever owned has, and I've had plenty of the things.

So no front suspension. Now the claim by Thorn is that it is hard on the hands/wrists?? It should be remembered that they specialise in tourers so possibly different over long distances??

I find it really nice on my arms. My last roadbike with carbon forks was a very old one, but this is def much nicer. Better than my flat-bar hybrid certainly. Just on my experience, they don't feel rough on my arms. The Syanapse as a whole is a fantastic ride.
