I prefer non-machined - the rims will last longer before needing replacing as the machining a) decreases the thickness of the rim wall at the brake track, and b) leads to variations in the thickness of the brake track around the circumference of the rim. Velocity offer quite a few of their rims in either machined or non-machined versions - I always choose the non-machined ones if they are available.
Jobst Brandt's take on machined rims was this: "*What you hear and read is mostly marketing hyperbole, but machining rims has its reason, and it isn't for your benefit. If you inspect a machined rim closely, you'll find a surface that looks as though made by a thread-cutting tool. The purpose is not to get a flat braking surface, but rather to produce a series of fine grooves to prevent brake squeal on new bicycle test rides.*" Nick On Thursday, 13 August 2020 06:08:58 UTC+10, Michael Williams wrote: > > I also had a question regarding machined vs non-machined braking surfaces. > Do people ride both on the list?
