Chain and Sprocket(s)

[Speeddog]

People still believe worn sprockets will wear a new chain faster than new sprockets? Lemme get this clear: I'm being told that brand new sprockets with a relatively rough coating that has to be worn off to make a smooth shiny surface wears on metal rubbing it less than a smooth shiny surface?

No, it's the distorted tooth profile of the worn sprockets that prematurely wears out the new chain.

I'd need to see proof, MCN-style. European Cycle Specialties about crapped themselves when they x-rayd my 916 rear hub because the excellent condition of my chain and sprockets. Was on 2nd chain and original sprockets at 40k miles.

But then again, my actual experience on my own hardware seems to often contradict "what they say", "common knowledge", and/or "what school taught me"...

Well...in any case I already purchased a supersprox stealth 40T 525 and have stayed 15T up front. Now since I'm playing with the drive, I am gonna do a few upgrades such as poly cush with titanium bolts, new sprocket cover and 3D chain.

If sprockets aren't worn to the point you can see lines or ridges in them, they're fine to reuse.

A worn sprocket actually has greater bearing surface than a fresh sprocket, due to the 'cup' worn into the face of the tooth.  Also, a new chain on an old sprocket will still have to 'wear in'... just like it would with a new sprocket.

Looks like I'm a bit late, but here's my take based on my old S2R1000.

I went with the quick change. Not only does it reduce the rotating mass (the hub is aluminum) but it pays for itself on the second sprocket change. Also, I went with a 520 kit instead. The 525 is overkill for the DS1000 and the 520 stuff is not only cheaper, but weighs less as well.

Well...I wanted to go with the QC sprocket but the dollahs were a bit short and I could not pass up the good price I found this sprocket for. Currently waiting for the chain breaker, socket tor remove the wheel and carrier coming from Italy...or somewhere over the pond.

So after losing a few weeks of riding, the beast is back on the road.
