When designing our JIS square taper bottom bracket, we made sure we designed it to last for a long time. It is well sealed against the elements and it has a patented design that makes it impossible to over tighten the bottom bracket and damage the bearings. Durability and light weight is assured, thanks to its forged alloy cups.
To make this one of the lightest bottom brackets on the market, we use a CNC machined hollow axle.This bottom bracket comes in sizes to fit double and triple road bikes, as well as triple mountain bikes and is for use with Shimano compatible cranks.
