My beloved '87 Centurion Ironman has a steel unicrown fork that seems to max out at 25c tires. I love the frame, but I've been doing more 'pave' and light gravel riding on my local poor-man's Paris - Roubaix (C&O Canal Trail) and have been wanting to throw on some 28s. I don't think clearance will be an issue in the rear, so I am looking for any ideas on good-value non-unicrown 1" forks.
I'd prefer steel over carbon. Threadless may give me an excuse to convert, but either will work.
Is this a reasonable idea, or would I be better off time/expense-wise just looking for a different frameset with better tire clearances?
