Details:
– Forged aluminum crank arm set that fits 110/74 BCD 5-bolt rings
– 42/26t aluminum chainrings, 10-speed (This is great for those who prefer a simple set-up and the quick shifting of a double and for riders who do a lot of steep climbing, but don't mind coasting downhill. )
– Aluminum chainguard in the big chainring position
– JIS square taper (110mm BB spindle for a 45mm chainline. 113mm BB spindle for a 47.5mm chainline.)
