I'm wondering if my rear shock is behaving as it's supposed to. I still need to adjust the preload to my weight, but that's not the issue I'm seeing. It seems like it takes more than a second to fully rebound, and the rebound is weak. Fully compressing it while standing next to the bike, then letting it go, has it raise very slowly to its normal height. Doing the same thing on my other bikes in the garage, and it comes up many times faster. Have I sprung a leak already?
