Extreme BB BB86 with stainless double-row angular contact bearing. Designed to meet the demands of elite Road/Gravel cyclists, MTB riders, and mechanics.

Here's why it stands out:

Key Features:

-Enhanced Durability

-Precision Engineering

-Protective Sleeve

Enhanced Durability:

Stainless steel construction resists corrosion, while the double-row design boosts stability and load distribution. This combination ensures peak performance during intense races and challenging descents.

Precision Engineering:

We've addressed the sensitive tolerances of BB86 systems, especially in DUB and 30mm setups. Our rigorous manufacturing process, monitoring the tolerance by technician, minimizes creaking and premature wear, guaranteeing a perfect fit and smooth operation.

Protective Sleeve:

Sleeves that prevent inner cable’s hose friction and potential frame damage, eliminating the risk of brake fluid contamination.

" With the MORTOP bottom bracket that was on my TCX. The bearings are extraordinary. Fluid. Fast. It’s WONDERFUL! " our ambassador Florian said.

We offer two specialized versions to meet the demands of different riding disciplines:

Road/Gravel Version:

Featuring a light contact surface side cover for efficient rolling, this version is inspired by the Taiwan KOM Challenge – one of the most gruelling climbs in cycling. The contour line pattern of Wuling adorns this model, symbolizing the Extreme BB's ability to help riders conquer even the most challenging roads without compromise.

Mountain Version:

Designed with a silicon cover, this variant offers superior protection against mud, dust, and other foreign objects that could affect bearing performance. It's the ideal companion for riders tackling extremely technical terrain and hard hits, ensuring your safety remains uncompromised.
