I like my rigid mtb from '98. It's got a couple things I'd like to upgrade though. The freewheel style axle is bent because I weight 230 and take it off drops. Is it worth upgrading to a cassette? looks like it's $90 for a cheap wheel and maybe 30-50 for a new cassette? also it's still running cantis and I'd like to upgrade to v brakes but that's another expense for an old ass bike.
What say you?
