Thanks for reviving this thread! I started at the beginning, and when I saw Clayton’s post, I looked at the date. “Ahhhh… that makes sense.”
You revised your question to ask about max fender widths. I run 52mm aluminum Velocity Orange Zeppelins over 38mm RH tires on my 2004 green Quickbeam. The fenders are crimped a bit to pass between the chain stays, but not at the seat stays or under the fork. I like the longer coverage for the chain in front, and I like to be able to wheel the bike around vertically on the rear tire. Setting the rear fender up normally shouldn’t need any crimping. I just changed my 37mm tires to these 38s, and had to flip a mounting bolt for more clearance under the bridge: https://www.instagram.com/p/ClkhqIjr9oU/?igshid=MWI4MTIyMDE= The new tires freshen up the bike, and I should probably straighten or replace the decade-old stays and add PDW releases: https://www.instagram.com/p/ClKbS02PGoN/?igshid=MWI4MTIyMDE= I would not put a bigger tire under metal fenders on this bike. Without fenders, my biggest tire was a 45mm Smoke with the side knobs cut off. The hassle there isn’t worth the reward to me, and a (~43?) Bruce Gordon Rock’n’Road is as big as I’d go in the future.
