Velo-Perso's premium recommendation for QO RACE and QO RACE Light cranksets on BB386 EVO frames.
A premium BB386 EVO bottom bracket for 29 mm DUB axles
When fitting a high-end crankset, the bottom bracket should never be the weak link. The Bikone DCTech EVO Ceramic combines hybrid ceramic bearings, precision-machined aluminium cups and Bikone Dual Cup Technology to create an exceptionally rigid, accurate and smooth-running system.
It is designed for EVO / BB386 EVO frames and cranksets using a 28.99 / 29 mm SRAM DUB axle.

Bikone Dual Cup Technology
The quality of a bottom bracket cannot be judged by ceramic balls alone. Bearing alignment, cup tolerances, rigidity and sealing quality all play a major role in how efficiently and reliably the system performs.
Bikone uses its Dual Cup Technology to connect the two aluminium cups into a rigid central assembly. This helps keep both bearings accurately aligned once the bottom bracket is installed.
Precise bearing alignment
A design engineered to keep both bearings correctly positioned
and aligned with the crank axle.
Hybrid ceramic bearings
ABEC5 / P5 bearings designed for extremely smooth rotation
and very low friction.
6061-T6 aluminium cups
High-quality corrosion-resistant aluminium, precisely machined
to maintain consistent tolerances.
Full sealing
2RS bearings, axial seals and fully protected surfaces combine
smooth operation with long-term durability.
Designed for 29 mm DUB cranksets
This bottom bracket is designed for cranksets using a 28.99 / 29 mm DUB-compatible axle.
It is therefore an especially attractive choice for QO RACE and QO RACE Light carbon cranksets, which also use a 28.99 / 29 mm axle.
This is particularly important when upgrading from a Shimano crankset with a 24 mm axle. If your frame uses the BB386 EVO standard, moving to a QO crankset requires a bottom bracket compatible with its larger 29 mm axle.

VELO-PERSO'S VIEW
An exceptionally high-quality bottom bracket, including in the small details that are not necessarily visible in a product photograph.
What stands out with Bikone is the respect for tolerances, the precision of the seals and dust covers, and above all the feeling of complete smoothness once the system is correctly installed.
There are no unpleasant surprises: every component appears designed to ensure that the axle and bearings operate in the best possible conditions.
In our view, the Bikone BB386 EVO Ceramic bottom bracket for DUB axles is quite simply one of the very best solutions available on the market for riders looking for a premium bottom bracket in this standard.
The perfect partner for QO RACE cranksets
QO road cranksets use a 28.99 / 29 mm axle. On a BB386 EVO frame, this Bikone bottom bracket therefore creates a particularly coherent system in terms of mechanical precision, smoothness and overall component quality.
QO RACE
Premium carbon road crankset combining low weight, high stiffness and aerodynamic design, with a wide choice of crank lengths and chainring combinations.
29 mm DUB-compatible axle: a perfect match for this Bikone bottom bracket.
