Buying Brakes. Which Drop?

Posted on
  • Simple question. I am getting some new callipers for the bike to replace the old Weinmann type 500's

    I have measured from the centre nut to the middle of the rim ( braking surface) and it's 50mm. So Do I get 49mm drop brakes or the 57's?

    I know most have +/- 10mm adjustment but is the stated size at the middle point?

    Sorry if these are dumb q's but I hat ordering the wrong parts!

    Cheers.

    EDIT: Bike is an old Peugeot Carbolite with 700c wheels. Nothing unusual

  • I think the drop number is the maximum rather than middle. For example

    http://www.wiggle.co.uk/p/cycle/7/Miche_Performance_57mm_Drop_Brake_Calliper_Set/5360040668/

    are 57 drop brakes but you can see the range is 41-57, whereas a 49 might have a range of 41-49. So as long as you can see the range and 50 is in there you can order away.

  • This ad on SF Craiglist is Weimann 500s which have 43-57mm reach.

    Velobase lists them as having standard reach. Not sure if there were 2 versions...

  • Sounds good, thanks for the info. It's just a bit annoying that a lot of specs don't show the adjustment range. BTW, the linked MICHE brakes actually look OK.

    Thanks.
