1 inch head tube fork upgrade question...
So my brother has an older Stumpjumper with a rigid fork and wants to get some suspension up in there...He was checking out a bunch of forks and found that his head tube diameter is 1 inch and most head tubes these days are 1 1/8 inches. Apparently RST makes forks that fit bikes with 1 inch head tubes. Are RST forks any good? If they are good forks and stuff he'll get one, but if it is a better idea to get a new frame he'll probably do that...
Any info would be appreciated...
