• Visually inspect your crank mounting tabs!
• Do NOT install our 48/32 on any crank/spider that does not look like this.
• Our 110BCD spiders have special tabs required for safe chain clearance/installation. This design allows our 48/32 set to be installed on our Praxis 110BCD cranks in conjunction with our custom ring bolts.
• Our spider tab design is also used by Cane Creek, Bingham and Specialized. (So visually inspect your spider first!)
