I don't think the fork is all too strong either. I've been told to keep the original Orange seat but I hate it.
I doubt I'll even start building it this year but maybe a HS33 on the rear and a disc upfront.
I know a 2.35 tyre fits in the rear as I threw on the wheel that's going on my P7 but to be on the safe side I think I'll go 2.1.
First thing, if I do anything would to strip it and get it powder coated again and new decals.
