ok, so i'm back, and i have a few pics. i'm not sure about this fork thats on the bike, any ideas? i have no real interest/need to replace it though, but seeing as not much of the components on the bike seem to be original, i was thinking it wouldn't be a bad thing to replace a few with some slightly nicer parts.

specifically the brakes. it looks like those kool stop ones would be the ones for these universal calipers, but i just saw some shimano 600s go on ebay for not too much. would they be better, more reliable, and/or easier to adjust? i'm not even sure if they'd fit, the reach on the rear seems to be really long, and the longest i saw was max57mm. (anyone have a spec on this?)

plus, i'm pretty sure the levers i have on there are crap, and used to have extension levers but been removed. i'd assue a nicer pair of levers with some nicer brakes together would be... well nicer?

anyway, any suggestions would be great.
