Tyre vs brake caliper clearance question

Posted on
  • I've put 32 x700 cross tyres on the frame (replacing 23c's) but the front one rubs beneath the brake caliper - i.e. the tyre is to tall to fit beneath the caliper (a Tiagra basic one).

    Is there a solution to this on a bike only drilled fro pivot road brakes? Other than changing forks or adding canti bosses etc - is there some sort of brake caliper with a 'lower profile' or something?

    Any suggestions welcome

  • 700 x 28c.

  • I'd primarily agree that getting smaller tyres is the easiest option... but on one of my bikes I've ground a significant amount of metal off the central knuckle of the brake in order to achieve a working clearance. Used a bench grinder and a half-round bastard file.
    I'm sure some boring old fart might want to explain to you how foolish that is, but it worked for me, my brake still works many many miles later and the sky hasn't fallen down yet.

  • Dug - I like that solution best of all. Now to procure a half round file.....

    Thanks both.
