Bottom Bracket Axle

The Bottom Bracket Axle from FITTOO Bicycle is a bicycle component that connects the crank arms to the bike's frame. It features a square taper design, which means that the end of the axle has a square shape that fits snugly into the square hole in the crank arms. The axle is designed to fit a standard 68mm wide bottom bracket shell and has a spindle length of 127.5mm, which is the distance between the two ends of the square taper.

The Bottom Bracket Axle is designed to be compatible with the JIS (Japanese Industrial Standard) taper, which is a common type of square taper used in many bicycles. Additionally, the Bottom Bracket Axle features two waterproof screws, which help to keep water and dirt out of the bottom bracket and prolong the life of the component. Overall, the FITTOO Bike Bottom Bracket Axle is a reliable and durable choice for cyclists looking to upgrade or replace their bottom bracket axle.
