I was going to rebuild my rear shock myself, but seeing as how I have never done it before and have had a ride planned since before I even bought my bike, I was affraid of messing up and missing the ride. So I gave up and took the shock back to the shop I bought the bike from. Turns out everything in the shock was bad, the nitrogen bladder, seal head, and seal. The original charge was $150. But since I just bought the bike the guy took $25 off the bill so $125 was the total. I'm still wondering if I shouldve done it myself, but hopefully its done right and I wont have to think twice about it. The good thing is that I dropped it off this morning before work, and by the time I got off work I already had a voicemail waiting saying that it was done so I picked it up as soon as I got off.
