There's a VISP trackie that cruises past me periodically going to work. The rider is a scrawny old barsteward and that bit of road is a prize sod, but I swear he passes me faster than any roadie has. Just goes to show it's the motor not the bike ... but we all know that ... don't we?

Serious question. My son has a VISP roadie from about 3 years ago. We built it up as a cheap commuter with second hand bits and wheels that were trued by coercion and black magic. He's now gone back to using his OCR2 "because it's a much better ride" surprise surprise. But this leaves the VISP doing nothing. I've got enough bits and pieces lying around to make it into a reasonable roadie, but it's still be an all aluminium frame. Would there be any advantage in fitting a carbon fibre fork? The objective would be a smoother ride. I'm not likely to use a roadie style bike very much so there's little value in my buying another bike when I've got the makings (apart from the carbon fork) here. Maybe I'm just looking for another project. Any thoughts?

Regarding the OPs question. There's little point in keeping a frame that doesn't fit. Cheaper frames often have a use in 'lesser' roles. He's got so many flamin' bikes it's nice to see him embarrassed for a change
