Alright I was wondering if there is anything special going on with the rear shocks that come on these bike's for example special valving or something? Or are they just ordinary rp2's and rp23's. The reason I am asking this is because I was thinking of getting an rp23 to replace the rp2 because it has more adjustment with the propedal features (3 instead of the rp2's on and off). So can I just get a regular rp23 and put it in there? I know I can but does Giant have special rp23's that would fit the bike better? Thanks in advance for any help.
