peadar Posted February 13, 2014 Posted February 13, 2014 Good Day All Tec hubbers.Quick question.I have a XTR and an X0 crank. I tried to put a Guesst 32 and 34 chain ring on but it doesn’t fit on either. The holes do not align up and are slightly out.Anyone have had the same problem?What chain rings will work with these cranks?

peadar Posted February 13, 2014 Author Posted February 13, 2014 mmmmmmm will have to get back to you on that.
Ysterperd Posted February 13, 2014 Posted February 13, 2014 BCD of both chainring and crank needs to be same. SRAM (GPX) has a 120 BCD, not sure about the XTR.
shaper Posted February 13, 2014 Posted February 13, 2014 (edited) you got the right BCD on the chainring? Edited February 13, 2014 by shaper
peadar Posted February 13, 2014 Author Posted February 13, 2014 appranantly not.thing the woolf tooth will work its a 120 bcd.
shaper Posted February 13, 2014 Posted February 13, 2014 If you have the gusset tribal R chainring used for 1 x 9/10spd then the BCD is 104 http://www.universalcycles.com/shopping/product_details.php?id=59702&category=5165

SRAM (GPX) has a 120 BCD, not sure about the XTR. XTR 960 (has 3 different bolt holes), the middle being 102mmXTR 970 BCD of 2 outer chainrings 104mmXTR 980 BCD 104mmXTR 985 Race BCD 88mm With the exception of the XTR 960, Wolftooth make one for each of them. Which gusset do you have? 104mm?
Skylark Posted February 13, 2014 Posted February 13, 2014 (edited) Not all SRAM GXP cranks use 120bcd chain rings.... Edited February 13, 2014 by Skylark
Jewbacca Posted February 13, 2014 Posted February 13, 2014 If you have the 102 bcd XTR crankset and a 104 bcd chainring, turn the chainring bolts around so the female is now on the outside and the male on the inside. This will allow you to 'marry' them no worries. SamL1220, Hairy, Captain Fastbastard Mayhem and 1 other 4

Was considering elongating the crank or chainring holes
Jewbacca Posted February 14, 2014 Posted February 14, 2014 See the inverted Chanring bolts, the 104bcd chainring with some cut/buffed XTR 102bcd cranks.... and the awesome pink chain! Captain Fastbastard Mayhem 1

Now, which to run on the Enduro bike? I'd given up on the XTR960 for that purpose till now. So.... XT 770http://www.wigglestatic.com/images/shimano-fcm770c.jpgor XTR 960http://fcdn.mtbr.com/attachments/singlespeed/702426d1339178289-jeff-jones-960-xtr-jeff-jones-steed-6.jpghttp://angelafung.net/P1020826.jpg
Motard660 Posted March 26, 2014 Posted March 26, 2014 I am probably going to ask a stupid question.....please bear with me. Can I make use of XT Middle Chain Ring (32 T) to convert it to a 1X10 Do I have to use a Chain Guard?
shaper Posted March 26, 2014 Posted March 26, 2014 I am probably going to ask a stupid question.....please bear with me. Can I make use of XT Middle Chain Ring (32 T) to convert it to a 1X10 Do I have to use a Chain Guard?If you have a clutch RD it may work, some have said that they have used normal chainrings and a clutch RD and have not had it jumping off. A chain guard would be the safer bet and you will know that you wont have that problem, else use a narrow wide chairning instead of the XT and clutch RD
MoreTrails Posted March 26, 2014 Posted March 26, 2014 Motard - yes you can, you will need: Chain guard - affirmative, either an XC guide (top guide only) or a full guide (top guide+roller) will work. It will either be fixed via chain guard tabs or if you don't have, then bb mount guide. Or frame mount top guide onlySpacers for the chainring bolts on the "male" side or shorter "female" bolts Clutch derailer and NW ring also works - as per Shaper above
