Rated 4.6 out of 5 by 5 reviewers.
Rated 4 out of 5 by For 83mm BB only Made the mistake of buying this over the M640 because it was cheaper. This one is for 83mm BB's only. 09 March 2014
Rated 5 out of 5 by Awesome! This is awesome! !! really strong for the price and it looks very nice! 27 February 2014
Rated 5 out of 5 by SOLID Don't think because you spend a shed load of money on a crank it will be better. This crank is solid and will give anything double the price a run for its money. Too many people go for looks and don't think about its purpose. 09 December 2013
Rated 4 out of 5 by Awesome Best set of DH/FR cranks I've used, plenty of strength and very easy to set-up out of the box 24 October 2013
Rated 5 out of 5 by Silent Great price. Great product. I've got these on 2 of my bikes now. 06 October 2013

Answer: 
This chainset has been designed to run with a 10 speed system, but will accept a single ring, 9 speed setup as well. The chainring teeth have been profiled to accept the narrower 10 speed chains, but the 9sp chain will also engage without issue.

Answer: 
To fit your Rockhopper the M640 version of the Zee chainset is required. The M640 has the correct length spindle.

You be able to run this chainset with a 9 speed drivetrain providing you use a 9 speed chain.

As you are converting to a single front ring you will also require a chain guide. The item below is what I would recommend.

Answers

Answer: 
This crankset comes with a Shimano Hollowtech II Threaded Bottom Bracket for use with frame Bottom Bracket shell widths of 83mm.

We are not a Voodoo Dealer but research suggests that the 68/73mm bottom bracket is what this frame requires; the correct crankset can be found below.

The only noticeable difference between the two models is the spindle length and bottom bracket spacing.
