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!)
