I was going to order the frame with a RC4 but found one locally with the dhx air.I've read that they have changed them for 2011 in that true? My last few bikes included a Bullit, Vp-free and Intense 6.6 SS all with coil front and rear. I've been out of the game for about 2 years so I don't know if the air stuff is better then it was. I'm having the same problem in choosing the fork also, do I go Van or float? I'm trying to keep the weight down, but performance comes first. Looking for some feed back.
