I am about to have a front wheel built up by Central wheels . Is it best to go for WM1 or WM2 width, do they give a different profile on a Michelin tubed eg. the WM2 wider width rim gives a squarer trread profile? Thanks.

Riding style dependable I think

1.60" (WM1) appears to have been the standard 21" rim width on a trials bike for the last 35+ years. However, the more recent bikes seem to mostly be going to 2.15" (WM3) rear rims instead of the WM2 (1.85") that was standard on the older bikes that I'm familiar with (KT250, etc).

cheers,

Michael
