Disc brakes and racing

There's every need. You think F1 or any other motorsport would go back and use drum brakes given the choice??
The performance is so much better they should be mandatory, never mind simply just starting to allow them, especially at pro level.

I have never found my rim brakes wanting. Bike racing is not motor sport, it's very, very, very different. Making them mandatory means you exclude all of us who can't afford a new bike from competing.

They're not necessary, and it's going to be an uncomfortable few years of adjustment in bunches.

I was actually thinking the opposite, when I ride in the bunch I stick within a few cm of the wheel in front. So far I have reacted quick to any braking. My concern was if discs gave that sudden jolt of a stop, then many riders used to close riding wouldn't have time. More to do with riders pulling brakes unnecessarily, which again, I imagine, is more an issue with A4s over others.

Probably over concerned, I certainly won't be getting a new bike no matter the route chosen.

Maybe I ride to close to other riders?

I am behind the times here... Are road bikes with discs using mechanical or hydraulic? Or is it both depending on budget?

depends on budget. i'm in the middle; hybrid, cable operated hydraulic brakes.

Didn't know this was a thing, will check them out, not for a road bike but something else that is limited to cable lever

Giant sell them as a conversion kit. Not sure whether they work with any brand, but I looked into it to convert my mechanical braked defy.

the ones i have are TRP hy-rd. work with my standard 105 levers.

A bit of a "mis-match" at the moment but, like mountain bikes, I would expect it to be almost exclusively hydraulic within a few years!

I find a really big difference between hydraullic and cable disc brakes. I won't get another cable disc brake bike, would prefer rim brakes to cable disc.

I may be under a misapprehension because the one bike i had with cable discs was shortly after discs became a thing, so perhaps they have both improved. also it was a hybrid for commuting and so the components were pretty low end, but i have bought a few hybrids with hydraullic discs since (for teh kids as well as myself) and notice a big difference. With hydraullics you can fine tune your braking, with cable it is more all or nothing - not quite but no fine control.

While discs do stop quicker for me the modulation is the big win for me, I have been left wanting for rim brakes on quite a few occasions especially on full carbon wheels

There are also Juin Tech R1s or the newer X1s as an option. R1s are kind of cheap enough.

I'm hunting down some hy-rds at present.

I thought the reason for banning them was due to different braking performance.

In a bunch on wet roads, one lad is braking on carbon clinchers and another is on discs. Going to get very messy, very quickly.

Bb7s are the only cable discs worth bothering with, used to be popular before the cost of hydro brakes plummeted. Not even sure if you can still get them.

Modulation is a feature of each brake model and how well bedded in, you should really bed in disc brakes on a bike.

Not a summer has gone by it seems where Borderfox is selling something I am actually looking for!

Going to update my view as I've new rim brake bike since. In the dry I see little difference between Ultegra Calipers and the mechanical discs. In the wet, the discs make a noticeable difference. I do have ongoing issues with brake rub (from on and off the direct driver turbo) with the discs, and the bads seem to get contaminated pretty quick on wet winter roads, resulting in regular squeals from the brakes. The rim brakes are just easier for me to manage/ maintain.

Mech discs are a poor brake, even the most basic mountain bike will ship with hydraulic discs these days.
I have a few thousand km's on my hybrid with never a squeak.
Just be careful when oiling your chain or lubing any part of the bike, and don't over do it.
If you do get a squeal, which my mountain bike will do, whip the pads out and stick them in the oven and bake the crap out of them. Works like a charm.

Will try that. I do think it's not cleaning the rotors as well. Like I said earlier, I find the mechanical discs better than ultegra rims in the wet. No difference in the dry. Have hydraulic on my mtb.

If you have access to a heat gun, I've found it useful when cleaning pads.

Can't see myself affording a new bike with disc brakes so it's standard for me till I'm finished racing.
Interesting to see how it all works out at lower levels all the same.

Finally found the inspiration I needed to get out of A4

€2399 for 2018 disc equivalent of my current bike but I'd likely need wheels as well which becomes a Del Boy style transaction process of buying, selling and B2W voucher, not sure if i want that hassle.

As someone just pointed out to me, the potential flooding of the market with decent second hand rim brake gear could be a blessing in disguise.

surely any new bike would have to have a single front chainring as well after sunday ?

To be fair in the last few races I have gotten very lazy and just cross chained pretty much all the time. I'd have no issue with a single front chainring on domestic races, the smaller chainring is just for show or desperation at this point.

Would anyone have any objections to putting up a second poll asking are you going to use discs on the road in this season or next, just to see is there going to be a mass conversion?

My little chainring gets plenty of action, hilly races are not my friend. Plenty of cross chaining also.
