Shimano XTR M985 Race Crankset

Hubbers,

 

I'm currently running a 3x10 2012 XT setup on my 29er. Itching to upgrade my cranks to maybe a 2x10 setup. I see that the XTR M985 cranks only comes in a 40-28T/ 42-30T/ 44-30T setup.

 

I dont have the legs for a 40-28T setup. Why no 38-24T like in the XT series?

40/28 with a 11/36 should be fine for anyone "who must have XTR".

 

Unless you are dik... if you use XTR your bike should be light and you should have the legs for the "Race" chainset.

 

If not, just get XT, it's half the price and it's awesome.

I'm riding the 42/30 XTR crank with a 11-36 cassette on my 29er, and have never really struggled getting up a hill. The 40/28 should be fine if you battle with climbs.

Tankman.... That's strange indeed! I've been on the Shimano cycling website this morning... M985 cranks only comes in a 40-28T/ 42-30T/ 44-30T setup.

 

Spoke to my LBS this morning as well.... looking for pricing on XTR chainrings .... Hmmmm. LBS told me 40-28T is the "lowest" ration that will work on the M985 cranks. The XT's has 38-26T rings, but according to my LBS....will not fit the M985 cranks.

The chainrings between 26/38 and 28/40 or 42 are not interchangeable, they are replaceable but bcd on the 26 vs 28 differ.

 

Ill post you a photo of the crank in a bit
