I`m thinking about replacing the existing Fox RP3 on my Giant Trance with a shock that can be fully locked out (RP3 propedal seems to have little effect) or has an SPV system that will give a lockout. I note that some i-net shops are currently heavily reducing rear shocks; but am unsure as to what maxm diameter will fit into the2006 Trance shock basket, I believe that it can be problematic... best to stick with LBS for this maybe? thanks
