Glory 2 fork help

As far as I know, all Rock Shox products are adjustable, in at least rebound and probably compression as well. And yes there are spring or air pressure options. Talk to your local bike shop and if they're worth their pay they should be able to help you out. If it's a World Cup then it's fully adjustable including the air spring. If it's an RC2C then the damping should be adjustable and the spring could easily be swapped out. The RC2C is well spoken of in many circles as feeling even better than the World Cup due to it's coil spring instead of air. I'd keep that fork and work out the details. Unless your really into spending money.

I looked it up over on the Rock Shox site and it appears that it has external rebound, usually found on the bottom of one of the legs, internal preload, adjusted by adding or removing little disks on top of the spring, and overall spring weight adjusted by changing out the spring.

Smash out some runs on that thing while you wait for a good deal on a Boxxer. They're solid stuff and I'm sure the Domain is too, just less adjustable. My old 32mm World Cup is still going strong.
