Advice on rear sprocket options?

[Emerson00]

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?

Do you know what QC carrier it is designed for? QC carriers usually only fit 1-3 different brands. I have a Sprocket Specialists carrier on my 748, and it can use their sprockets or AFAM. Personally, I'd go the QC setup. It'll save you a bit of money in the long run - that is if you plan on keeping the bike. I found a used QC carrier on eBay several years ago and only paid $75 shipped for it. You may get lucky and find a carrier that will work with that sprocket for cheap. BTW, if you get a QC carrier, make sure that is has the shoulders that prevent the cush drives from backing out and eating up your hub/swingarm.

Theoretically, they should last as long as a steel sprocket. I recently bought one for my Bimota, but have yet to install it. As for the mileage you get... That is dependent on a lot of different factors, with one of them being the size (520, 525, 530?). I've killed 520 chain and sprockets in as little as 11k miles. The 525 chains I run typically last 18k-24k. The 530's last about the same as the 525, but my wife currently has over 27k miles on a set of 530 chain and sprockets on her R1. I've heard of some people getting well over 30k to a set of sprockets....there's also the question of when do you consider the chain and sprockets shot and worthy of being replaced? I used the OEM 525 rear sprocket on my ST2 with two chains (because it looked that good). It had about 36k miles when I took it off. Due to an alignment issue when a sprocket retainer failed, it is currently back on my bike and has about 38k miles on it now.

Thanks. I ordered a supersprox one piece and will sell off the QC sprocket. I figured the cost is comparable in the end if it gets even twice the mileage (QC is just anodized alu, not even hard ano); the 1-piece is closer to standard; and in the short term it's cheaper - in the end it'll cost $100 more than expected instead of 160 more.

I plan to keep this one long-term but you know how plans go.

I do appreciate the advice, and relating your experience - this is my first chain/sprocket replacement. My chain was junk, the front sprocket worse than I'd expected, and the rear is ok but showing signs (at 15k mi). I went with 525 and EK x-ring, and hope to get more miles on this set up.

I didn't see this til now. I also bought a Supersprox last summer for all the same reasons. I had a quick change and the sprockets are light alloy and wear out pretty fast. I was very unhappy with that solution.

I bought a steel AFAM sprocket for my QC carrier. They rarely are advertised, though.

Thanks! Good to know.
