Lets talk brakes..

You're not the only one by any means.

I'm not most retro of retrobikers but I really don't see the weakness of V-brakes that means that no decent manufacturer is capable of putting bosses on forks any more. A couple of months back I took the plunge with cable discs when I had the chance of getting a nice set of disc wheels pretty cheap. The setup was XTR levers, Avid BB7s, a quality compressionless cable outers - about as good as it's supposed to get for cable discs. Even aware that they probably wouldn't be at the same level as a hydro setup, after hours of fitting, adjusting pad clearance, bedding in, truing discs etc, I was completely disappointed. 2 different pairs of brand new discs seemed to need constant truing with no more use than a test ride or two round the block, and the tolerances in the pad clearance seemed so marginal that they would just need constant readjustment to get a setup that was barely usable, let alone anything better. Personally I couldn't get the performance close to matching the level of XT/XTR V's or the higher end Avids, before even considering the amount of fiddling that would be required to do it compared to setting up V-brakes. And to boot, the whole set up was a fair bit heavier, with some of that carried in the rotating weight.

I would be happy enough just to continue bucking the trend with V-brakes on my bikes while there are plenty of decent quality second hand ones around in good condition (and even cheap ones work fine) but the fork manufacturers are the killer as the decent ones that still have bosses are far harder to come by in the second hand market as their lifespan is limited.

100% agree. Tried cable discs, pure sh1te and they're were set up correctly and a quality set. I still love cantilevers. When set up with 2mm XT pre stretched cable and good blocks, they can still lock the front wheel. Obviously I can't descend a steep rocky trail as fast as a modern hydraulic disc adapted rider but I get as much of a buzz going along at 20mph as he does at 40mph and I don't have quite the same fear of ending up in Stoke Manderville's spinal unit if I crash when a tree suddenly jumps out.

Really? Ill bet todays tdf rider will leave any of those that took part in tdf 60 years ago way behind. Better nutrituon and training, not to mention drugs, ensures that.

Lemond set a TdF individual time trial speed of 54.54km/h in 1989, beaten this week by Rohan Dennis at 55.44km/h setting the fastest ever Individual Time Trial in a TdF stage. But Dennis rode for 13.8km whereas Lemond kept it up for 24.5km.

Statistics from 60 years ago are hard to find but in 1960 the average speed for the TdF was 37.2kmh and in 2014 it was 39.5kmh, some of the doping years in between recorded average speeds in excess of 40kmh though.

It appears to me at the Elite level the only significant gains are achieved through technology. At my level, I am no faster than my counterpart from 60 years ago, I am sure of that :).

Some of the fastest cyclists are the downhill racers, cant see them going back to v brakes.

Neither can I.

Re fastest cyclists over distance, the reason why you dont see disc brakes on tdf bikes is because they are banned by the uci - just googled that so it must be true. Partial ban to be lifted sept this year so lets wait and see.

That is interesting, thanks for posting it.

That is such a good price it will make my decision to build a disk equipped bike much easier, thanks for posting it.
 
Not sure why this has turned in to a bun fight.

Disc brakes, especially hydraulic, perform better than v or cantilever. End.

Only reason anyone is using v or cantilever is because that was all that was available at the time the bike was purchased.

I dont think anyone is saying you should ditch v or canti, if you are happy with then fine, they do an adequate job but not as well as hydraulic disc.
 
I wonder at what point the stopping power of discs will far exceed the traction of tyres, resulting in super sticky (and super expensive) F1 style rubber hitting the market?
 
^^^^^ dont get that. Surely it depends on how hard you squeeze the lever?

More interestingly will there be abs?
 
ABS, yes of course, the next logical step. Shimano will love that. Also fault codes that prevent the bike moving if the ABS isn't working correctly.
 
Re:

Ha ha yeah it'll probably all end up like cars you'll have to go to a dealer if somthing goes wrong so they can read the faults and charge a small fortune to put it right.

I think I'll keep it simple who needs abs :LOL:
 
Re:

I use V-brakes on my 3 modern mtb's, '98 - '02. They give me all the power I need, if I need more then I'm heading for a crash anyhow! :shock: :LOL:
Even have a few spare sets stashed away!
