I need a new C+S sprocket kit and it’s the NEC bike show soon so might see if I can get something there. BUT….I’m rather confused…about, quite a few things.

Chain link
The Last chain I fitted to a bike was an “endless” chain so I had to take the swing arm off to fit it, which was fine as it was coming off anyway for a service (Just like my Ten’s will be). So with split links / soft links…are there different types?

Chain
People seem to rate the DID VXM chain which is X ring (yeah?). But don’t you need a special chain tool for DID chains?? I’ve used EK before and really rated them, seem hard to get now??

The DID chains on Wemoto say they're a 100 links? But the standard (****!) chain is 110? Think i'm going to go 525 as well.

Sprocket make
I bought a 14T JT and it didn’t fit, its kind of put me of JT sprockets (I know some one else who also had one and it wouldn’t fit). What are my other options?

Sprocket size
Running a 14T Renthal at the mo, don’t really like it though. It is a bit better when going slow, but quite a bit ****er when going fast. Thinking of maybe going 1 tooth up on the back…kind of a “middle ground”.

Sorry for all the questions…..

Thanks
Phil
