depends on what frame fork combo your using, but a short reach caliper is needed for sure. i have a few, weinman and shimano 60 and 50 mm reach. look at some mini's in the museum

give me a sec, i'll grab the tape :LolLolLolLol:

nice one :daumenhoch:
-
46cm outside edge diameter. so i guess 22cn from axle centre to brake block centre.

nice one, looks like the caliper isn't going to reach. i know at the most the caliper has a reach of 60mm and this would mean the axel will be butted right up into the rear dropout. so i need a longer caliper, around 80mm.
this is with the axel being fitted around the center of the dropout.
many thanks for your help :daumenhoch:
