So I already have a trail bike, but it's a 34lb trail bike. I want to do some more XC this year, and wouldn't mind riding a HT if it means it could be (relatively) light. What would you build up for a cheap, light (do those words go together) XC bike? Maybe a cheap frame off ebay -- some sort of light aluminum. What's a light-ish fork? Aside from going full xtr or x.0, any good places to cut weight?
How to get <$1000, and less than 25lbs?
