I recently bought a used 2004 Santa Cruz Heckler w/a 5th element shock. First full susp. bike, so I don't know a lot about rear suspension. Bike is in great shape, but the spring on the 5th is rusted from garage storage. Wanted to replace the spring, but not sure what size I need as I can't read the numbers on the current spring, and it seems Progressive doesn't make mtb suspension anymore. Frame is an XL and I weigh around 215. Also thinking about just getting a whole new rear shock, so I'm open to any recommendations. I do a mix of trail riding, with some dirt jumping/slightly more aggressive riding on occasion.
