Shimano Zee Chainset 10sp M640

Class-leading XTR 10-speed Dyna-Sys chainset, integrating the bottom bracket and chainset into a strong, rigid, yet lightweight unit.


  • Integrated design makes installation and adjustments easier than ever.
  • Precision bottom bracket bearings are spaced further apart, and are therefore more stable and longer lasting than conventional bottom brackets.
  • Super-lightweight HollowTech II forged Duralumin crank arms - hollow design saves weight whilst increasing rigidity.
  • Easy to use splined bottom bracket spindle connection provides a rigid and secure interface between crank and spindle.
  • Close ratio gear combination: 42-32-24T provides improved cadence while reducing pedal feedback on suspension bikes.
  • The middle HG-X chainring is made of titanium supported in a carbon shell which combine to produce a hard-wearing, light weight, and stiff set up.
  • Stiff, light weight and hard-wearing HG-X 7075 aluminium outer and inner chainrings with a highly durable Nickel-plate treatment.
  • HG-X chainring with patented spike pins give smooth and fast gear shifts under load.
  • Chainrings: 104 / 64 PCD four-arm .
  • For use with: 10-speed HG-X MTB chains only.

Rated 4.3 out of 5 by 3 reviewers.
Rated 5 out of 5 by bling Not only does the chainset look good it also performs really well. I replaced my old deore and shed 250g in weight including the bottom bracket. I did need to adjust the front mech slightly which only to a few seconds. Very pleased with the service I recieved from CRC also. Never cease to amaze me. 20 April 2014
Rated 3 out of 5 by Fantastic performance, but not worth the price First off, I think this is a fabulous crankset. Performance is what you would expect from XTR. However, my XT M770 crankset is fabulous, too--and cost less than half this one. In fact, I can't tell any difference between the two when riding unless I look down. Yes, the XTR's looks are awesome, but the black finish is easily scratched and scarred, so it doesn't hide wear as well as the silver arms of the XT model. Factor in the cost of replacing the chain rings, and, although it's a great functioning piece of kit, it's just too expensive for me to recommend. Go for the XT M770--you won't be disappointed with performance and you can use the cash you save to upgrade elsewhere. 03 April 2014
Rated 5 out of 5 by Great design and quality in keeping with XTR's reputation Quite blingy so be prepared for a raised eyebrow if trying to sneak this onto your bike - she will notice, especially if you are upgrading from an all black XT set. My digital kitchen scale showed exactly 760g with the supplied (nice bonus) BB so it's lighter than the XT double even. Very easy to install. I upgraded from the XT triple and it took me less than 10 minutes as the chain line is the same. In use, shifting is as brilliant as expected, low Q factor allows even more heel movement (vs XT) and it feels stiffer too. Unbeatable value at the CRC price as well. 02 December 2013
