Rim vs. disc brakes - which will win most stages in TdF 2020?

neebneeb Posts: 4,413
On the first rest day the score stands at 5 - 4 in favour of rim brakes. Which will win most stages overall?

Go rim brakes! :)

    It's the new Campag vs Shimano for dullards, isn't it?

    Neither. And it won't be the bikes either, it will be the riders.
    The above may be fact, or fiction, I may be serious, I may be jesting.
    I am not sure. You have no chance.

    Your fun level must be set lower than mine. 😉

    That's blindingly obvious (the performance differences are insignificant at pro level, possible faster wheel changes for rim brakes aside). But It'll be a finely balanced outcome this year dependent on relative dominance of J-V, Ineos, AG2R etc in stage wins, as well as the individual choices of likely stage winners from other teams.

    Why don't you write an impassioned post about why the one you bought is the best..?

    It’s taken you over 4,000 posts to work that out.
  • neebneeb Posts: 4,413
    A tiny fraction of which have been in Pro race, for the above reason.

  • So if the rim v disc stage count is abandoned now that means rim brakes win yeah?

    Why ask the question then?
    Don't say fun. I'd be disappointed in you if you think that debate is fun.

    Yeah but 5lavging off dumb topics is part of the fun .. go rim brakes

  • Seems like more teams are shifting to the MTB discs at the tour this year instead of Dura ace rotors!?
    Nobody know why however.


    I have a feeling it's something wrong with the road discs. - mainly shimano.
    My Dura ace discs rub after short but hard braking. I wonder if the design is flawed and bends too much under heat?
  • So which will win more, MTB or Dura-Ace disks would be a better and more nerdish question

    Interesting. Is it just different rotors or calipers too ?

    Which ones do you think they're using then? XTR rotors?
  • Yeah I googled it there's a story on one of the cycling news sites. It lists who is using them but they only speculate as to why.

  • I wonder if it could be something as ridiculous as availability.

    Seems the XTRs are lighter than DA so that's probably reason enough in itself.
  • Just looked into this and it's DA calipers. They are changing the discs though.

    Can it really be weight!? Weight wise it means nothing as it's about 20g and the bikes are on the UCI limit almost anyway.

    The DA and Ultegra discs are designed for road as the ice tech fins are much bigger to offload the heat generated with high speed braking.

    I'm not sure the disc braked bikes necessarily are on the UCI weight limit though, particularly those riding bigger sizes.
  • I can see rim brakes sticking around. There doesn't seem to be a performance advantage downhill for discs but there is one uphill for rim brakes.

    Despite manufacturers pushing discs the extra complexity, weight and expense is a genuine disadvantage for those of us who buy and maintain our own bikes and aren't constrained by the uci weight limit. Ok so you don't wear out your rims - does anyone actually get through many rims on their "best" bike? With direct mount calipers we can even have wide tyres without discs now.

  • i will go disc I suspect cos if I get a new frame its likely to be disc. i like the lack of rim wear. i feel underwhelmed by it thou.

    TdG doesnt ride discs or electric gears bike packing. not like he couldn't if he wanted

    The biggest advantage seems to me to be the ability to do really fast wheel changes and to take neutral service wheels

    Neutral service need to get with the times....

    Are all the manufacturers using the same disc and axle standards yet? I don't think they are - especially the thru-axle

    Seems like a very solvable problem to me...
