Victory Circle Graphix in Golden, Colorado. They have an online interface where you can order them. They do a lot of work for pro teams and do a really good job, very high quality.
I’m putting the Qrings on mine too. Is this your first ride on Qrings? I’ve been using Rotor Cranks for over 4 years but with the Look cranks I’ll be using the Qrings.
Did you change to this seat post for a reason and not use the forward one?
I’ve been on the Q Rings for about 2 years now. I really like them and they seem to work but I have no empirical evidence to support that.
I used the 5mm post mostly for aesthetic reasons. With the R32 the seat would have been either pushed all the way forward with the post in the rear-facing position, or slid all the way back with the post in the forward-facing position. Nothing really functional about it!
