ISO Square Taper
When designing our ISO 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. The standard version uses a cromo axle but if you are serious about weight savings, it is also available with a titanium axle. And for those who appreciate a very smooth bottom bracket, you can get this bottom bracket with our ceramic TBT bearings.
This bottom bracket comes in sizes to fit double and triple road bikes, as well as triple mountain bikes and is for use with Campagnolo compatible cranks.
Premium Bearings are our high carbon steel bearings.
TBT bearings are made with ceramic balls and extremely hard races for very low rolling resistance and long-lasting performance.
