The aluminum wheel works better with the aluminum discs. I'm assuming that you'll be changing out the rear also.
How was the ride? I remember when I rode it in Cleveland lat year, it had a real unique feel to it. The sprung rear triangle gives it a different feel than a normal frame.
Yeah, I'll be replacing the rear wheel too. I remember finding the build pics that Josh had of this wheelset and I loved the paint and rust patina on them. I knew I wanted to uncover them and save them for another build someday. I also have a SRAM Automatix on it's way that I want to lace up to to an alloy rear rim.
I describe the ride above. Most of the time when you are riding you don't really notice a difference, but like I said when you wiggle the steering, it has a bit of a wobbly effect. Not quite squirrelly or unstable, but different for sure.
predictable!!! But still cool!
