JIS Square Taper - TK866CM

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. 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 fitted with TOKEN 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 Shimano compatible cranks.

Axle lengths available:
103, 107.5, 110.5, 113.5, 118mm for Double Road
113.5, 118mm for Triple Road
113.5, 116, 118, 122.5, 127.5mm for Triple MTB

Comes with  a pair of bolts
