9sp crankset with 8sp everythingelse - will it work?
Hi again,
I need to buy a new crankset. It looks like there's far more choice in 9sp-compatible cranksets than 8sp cranksets. But all the componentry on my bike is currently 8sp. So - will a 9sp crankset work on my 8sp derailleurs, chain and cassette? I've done some research on the web and I'm now a little confused. Some people say a 9sp crankset will work just fine. Others say the 9sp crankset have reprofiled pick-up teeth that won't work with an 8sp chain so you have to change the chain to a 9sp chain. The 9sp chain will work fine with the 8sp cassette and derailleurs. But I'm not keen on the idea of a 9sp chain because I've read that 9sp components wear down up to twice as fast as 8sp components. Help! I currently have my eye on an M572 LX splined 9sp crankset and an XT ES71 splined BB. Thanks, Jack |

A 9 speed crank will work fine with an otherwise 8 speed drivetrain. The only real difference is going to be a slightly smaller space between the two chainrings - hardly enough to get excited about.

Thanks for your advice, everyone. I've just placed an order for Shimano LX
M571 splined crankset and a 121mm LX ES51 splined BB. Goody! Jack. "Mark Hickey" wrote in message ... "Daniel Kelly \(AKA Jack\)" wrote: I need to buy a new crankset.

9sp crankset with 8sp everythingelse - will it work?
I'm running 9 speed cranksets with 8 speed chains, cassettes and shifters on
two MTBs right now - an XT FC-M760 w/ the integrated BB on my hardtail and an XT FC-M752 splined BB set-up on my full rigid MTB. I've noticed no real difference in shifting performance compared to full 8 speed setups. I'm also using a 9 speed front derailleur on the hardtail with no fuss. The only real problem I have is with my splined XT crank/BB setup. It developed an intermittent clicking noise soon after I installed it last year that I just can't get rid of no matter what I do. All the trouble-shooting I've done (including wapping parts around from bike to bike and replacing the BB) has points directly at the splined BB/crank interface. No amount of cleaning, tightening or greasing gets rid of it permanently. |

Hehe. If you insist... Crankset: http://www.shimano-europe.com/cyclin...=10205&psid=24 BB: http://www.shimano-europe.com/cyclin...=11144&psid=24 What is 'splined' (duh)? The Shimano website explains it as: "Octalink Crank Arm Mount Eight splines on the oversized hollow bottom bracket spindle mate with the crank arm to form a stronger and more rigid interface."
