I wish it were the spacer but that's in place. I swapped the wheel off my hardtail onto the Prophet and after touching up the dearailleur went for a ride. Not a single skip or ghost shift. When I got back home I pulled the cassette, installed the skewer with a wrench in place to act like a dropout, and the freewheel still has play in it. I'm going to take it to the shop tomorrow and have them look at it again but I think that it's going to need a rebuild. The bike is only about 9 months old and already the pawls inside the hub have disentegrated and been replaced and now this! I would think that Mavic will warranty this but this doesn't bode well for the future.
So, I like the wheels but the rear hub is crap apparently. Is there any reason why I can't call up Chris King, order up a 24h hub, and lace it into this wheel?
