Q: Want to install this on the sette razzo 29er with the 170 crank arm length . This is compatible right?
A: The M640 crankset is compatible with the Sette Razzo as it uses a 68/73 bottom bracket. Crankarm length would depend on the rider. Feel free to shoot us an email or a call if you have any further questions.
Q: Interested in this single sprocket design. Wondering if there would be an issue fitting it to a 2012 Giant Revel 0?
A: These are excellent cranks!! You would have to contact Giant to find out what bottom bracket type your frame takes. These cranks are for 68/73mm.
Q: Is the chainring bolt spacing 104mm?
A: Yes, the BCD is 104mm.
Q: Does this have a narrow wide same as what the famous RaceFace have? Thank you
Figured I'd try these for my SS, with the Z for ZMAN (me) and all. A bit heavy but easy install with the included BB, nice finish, the torx ring bolts are great for positive fastening. No more loose cranks from the square taper..yesss.
