I bought everything for fr/rr sprocket and chain replacement. I missed that the rear sprocket was only $65 because it was for quick change hub; I didn't buy the qc hub, and now need to either cough up another $155 for the qc hub, or look at other options. Restocking fee for the qc sprocket I already have is 50%... It's not very quick w/o a quick change carrier/hub. With the chain, front sprocket, rear QC sprocket, and chain tool I'm already out $450. Not to whine, but the money tree's been sick lately.
Option 1, quick bitching and buy the QC hub. Honestly this only sucks because I dislike spending another $155.. OK, what I actually dislike is explaining to the wife that this maintenance cost went up to $600

. I also don't think the rear sprocket I have now is particularly high quality; can't say why but it looks/feels cheap.
Option 2, sell the QC sprocket on CL or eBay, and buy a supersprox one piece rear sprocket/hub for $159... California Cycleworks makes the odd claim it lasts 3x longer. If that were true it'd be the less expensive option, and my SS swingarm makes the change easy enough I don't care about quick change.
As usual I just want the damn bike back on the road.

Thoughts on these? How long does Supersprox actually last? I'm changing my current rear at 15k miles and it's not worn much; would a supersprox realistically last 40k miles?
