These cranks are a great option for any mountain bike. Available in a wide range of lengths from 140mm to 210mm and set up with a Sram 3-bolt direct mount system for chainrings. If your bike has boost rear spacing, you want to use a 3mm offset chainring. If you have a 12x142mm or 10x135mm rear axle spacing, you want to use a 6mm offset chainring. If your bike is super boost or if you have chainring clearance issue with your chainstay, choose the 0mm offset option. 

• Chainring included - choose option
• BSA bottom bracket included
• Bottom brackets for other BB shell types sold separately
