I'm looking at buying a new shock for my Rush, as I mentioned in another thread. I think I'm going to go with the 2013 CTD boost model, but I'm trying to figure out the new setup they have with low volume/high volume air cans. Apparently, LV is now "large volume": http://www.foxracingshox.com/technology.php?m=bike&t=lv&ref=topnav. Can I still get a small air can shock? I need the progressive rate for my swingle pivot. If not, can I get volume reducers for the 2013 shocks? I'm not really "in the know" but looking at various mail order joints, you can get a 7.5x2 and a 7.5x2 high volume shock.
