Breaking an Ultegra 6700 10sp chain
Just bought a new road bike with a 6700 drivetrain (except the FSA crankset). The chain is a few links longer than what would be optimal, though. While I might take it back and have the shop look at it, I'd like to at least know how to break/reconnect the chain myself. But apparently these new chains don't work quite the same way as the old 6sp chains I'm used to.
1) As long as I reconnect with a fresh Shimano 10sp pin, is the disassembly and assembly process the same as with 'normal' chains?
2) Can I use a quick link of some sort? Preferably one that doesn't require tools.
3) If I need to replace the entire chain, will any 10sp chain do? Or do the chain and cassette need to both be of the same brand for the ramps and pins and stuff to function?
4) Is there anything else I should keep in mind while dealing with these chains?
