Road Discs vs MTB Discs?

Is there a difference between mechanical disc brakes for use on a MTB and those for road bike?

I want to put drop bars on a MTB (for good reasons!!), and so need to use Road STI Levers. Can I use this with standard MTB disc brakes (BB5 etc) or do they need to be specific to road levers




sorry for double post, but the same question has to go in Road and MTB Sections

    No, as some calipers are designed to work with the different lever pull of a roadbike.
  • I've not seen a road bike with discs. Have you got an example?

    Hybrids which have discs are closer related to MTB geometry than road anyway, I don't think I've ever seen a bike with drop bars and discs.

    (With the exception of that F1 design project last week, but a £30k prototype doesn't really count, does it!?)

    ETA: Just re-read your question, you couldn't use drop bars with discs, as Super says, the leverage would be different.

    What's your reason for having drops on a MTB?

    Actually, you can. It was done for years before the road calipers started coming out. The brake feels quite different (can't remember if it's mushier or sharper, I think it's mushier) but it works, and the longer levers on STIs means there's loads of power available.

    I must admit, I'm tempted to put drops on my MTB...

    Then you haven't seen many bikes...

    Lemond Poprad

    Kona Sutra

    Focus Mares Cross Disc

    Something, not sure what
  • Wow, thanks whyamihere! Some very cool bikes there! I especially like the Lemond and the Kona Sutra. The Kona has a more hybrid look about it, smaller frame with more relaxed geo.

    Yeah, goes a bit squidgy IIRC, like running V brakes with none V brake levers. Can feel really powerful, but harder to adjust the pad to stop it rubbing.

    Put slicks on. Then they're road bikes. ;)

    You could just use a travel adjuster...
