Rollingstash- Played with the rear shock for the four seasons I've had my 2000 NRS XTC1. I weigh 205 - 200 pounds depending on the time of the year (us old folk get real lazy during the winter here on Long Island). I set the positive chamber for my weight plus 20 pounds. This completely eliminates any bobbing when pedaling.
The (rebound) problem occurs (IMHO) because the positive air spring pressure is so high. Giant specifies 50-pounds as a starting point for the negative chamber but both Giant and RockShox had me increase that in 10-pound increments to improve the rebound damping. At 80 pounds some small improvement in realized, but not enough.
Giving up and will send the shock (this winter) for a rebuild to (forgot name) a company started by a bunch of guys who left RockShox recently. Company name is in a recent issue of MB Action. I'm in heaven for those fleeting moments that the rebound works; otherwise, it's a pogo stick. Lighter people should not have this problem.
Frame is fine; I don't go looking for a lot of air. Know some people here on the Island who have broken there frames. Giant gave them BRAND NEW BIKES without any hesitation. Tough to beat that!
