BIKONE · PREMIUM CYCLING BOTTOM BRACKETS
From a dependable BB86 replacement to a top-level Colnago or Tarmac build, Bikone offers a focused range of steel and ceramic bottom brackets. Velo-Perso helps match each unit to your frame and crankset, backed by real product photography and in-house weight measurements.
FIND YOUR LEVEL
The differences are bearing type, cup design, weight and price. Correct compatibility and careful installation remain essential to a dependable build.
Precision steel bearings, carefully designed cups and reliable sealing. A strong option for frequent riding, replacing a worn bottom bracket and keeping the budget under control. Often our pick for Shimano BB86 / 24 mm.
Explore steel BBs
Hybrid ceramic bearings and a construction focused on smooth running and accurate installation. A premium choice for demanding road and gravel builds, without paying extra for the UAE finish.

BIKONE ENGINEERING
Bikone draws on bearing expertise from Fersa. DCTech engineering combines cup geometry, bearing protection and installation tolerances. That is why the complete assembly matters, rather than judging a bottom bracket simply by whether its balls are steel or ceramic.
The cups are designed to locate and guide the bearings precisely. Careful installation and a frame within the correct tolerances are still essential for quiet operation.
Radial and axial seals, along with other protective interfaces, help reduce contamination from water and dirt. Longevity also depends on riding conditions and maintenance.
Steel bearings are sensible for high-mileage use at a controlled cost. Hybrid ceramic bearings combine ceramic balls with metal races; their efficiency depends on the complete system, including seals and lubricant.
RANGE 01 · PRECISION AT A FAIR PRICE
DCTech steel covers common standards and less familiar frame interfaces. Cup construction, sealing and bearing guidance are central to its design. For bikes that see frequent mileage, this is often the most sensible investment.
RANGE 02 · PREMIUM PERFORMANCE
The ceramic range uses hybrid ceramic bearings and machined cups. We recommend it for already well-equipped bikes, where accurate fit, mechanical quality and consistent smoothness are the priority.
RANGE 03 · WORLD TOUR
The blue BSA Aero uses 7075-T6 aluminium cups, hybrid ceramic bearings and a smooth outer “Aero Cup” with hidden tool engagement. The design reduces weight and refines integration around the bottom bracket area. Any aerodynamic benefit is expected to be very small and has not been quantified by Velo-Perso.
The 2026 TDF Gold edition uses the BSA Aero architecture with an exclusive commemorative gold finish. Hybrid ceramic bearings, 7075-T6 cups, 24 mm spindle, 68 mm road BSA thread and installation accessories are included. It is designed for exceptional bike builds and riders who value fine components.
These photographs show the 2026 TDF Gold release and the accessories supplied with this edition.
The blue UAE T47 PowerSet addresses compatible T47 installations. It is not interchangeable with BSA or every internal, external or asymmetric T47 configuration. It mainly appeals to owners of the corresponding frames; DCTech steel and ceramic are the natural options for most other setups.
FRAME + CRANKSET
A Shimano-compatible bottom bracket does not automatically fit every BB86, BSA or T47 frame. Check both parts of the system, plus required spacers and the bike generation.
| Frame shell | What to check | Shop / Guide |
|---|---|---|
| BSA threaded | 68 mm road shell, BSA thread and spindle size | BSA steel |
| BB86 / PF86.5 | Ø41 mm shell, approximately 86.5 mm wide, 24 / 29 / 30 mm spindle | BB86 steel |
| T47 | Shell width, internal/external cups or T47A | T47 ceramic |
| BBRight / BB386 EVO / PF30 | Shell diameter, width and exact frame standard | Complete range |
Typical spindles: 24 mm for Shimano and some Rotor cranks; 28.99 mm (DUB) for SRAM and selected other cranks; 30 mm for several Rotor and other cranksets. Wide variants and spacer setups also matter. Do not select a bottom bracket by groupset name alone.

FREQUENTLY ASKED QUESTIONS
DCTech steel prioritises value, reliability and regular mileage. DCTech ceramic is aimed at more premium builds, with hybrid ceramic bearings. The best choice still depends on your frame standard and riding conditions.
No. Any gain is marginal. The BSA Aero UAE focuses on construction quality, low weight and the smooth Aero Cup finish. We have no independently measured aerodynamic watt saving to quote.
The 2026 TDF Gold uses the BSA Aero technology with a commemorative gold finish and collector presentation. Both are designed for compatible 68 mm BSA road frames and 24 mm spindles. The 2026 Gold differs from the 2025 limited release.
For Shimano Hollowtech II 24 mm cranks, choose the bracket matching your frame: for example BSA 68/24 or BB86 41/24. Steel is particularly sensible for 105; ceramic can suit a premium Ultegra or Dura-Ace build but is not required.
No. The BSA UAE Aero and 2026 TDF Gold models featured here use a 24 mm spindle interface, while SRAM DUB spindles are approximately 28.99 mm. Choose a compatible BSA DUB model instead.
Both belong to the Ø41 mm PressFit family, but shell width and intended use differ: approximately 86.5 mm for road BB86 and 92 mm for many MTB frames. Check the crank spindle and spacers too.
No. T47 internal, external and T47A configurations require different shell widths and cup positions. The exact frame geometry must match the selected product.
Bikone claims 77 g. The unit pictured by Velo-Perso registered 79 g on our scale. We distinguish the manufacturer figure from the in-house measurement.
No. Ceramic bottom brackets still need correct installation, effective sealing and routine inspection. Avoid spraying bearing seals with a high-pressure washer and check for play, noise or water ingress.
Identify your frame model and year, exact bottom bracket shell and the spindle diameter of the crankset actually fitted. Use the Velo-Perso Bottom Bracket Finder or ask for a compatibility check before ordering.
Tell us your bike model, model year and fitted crankset. Compare steel, ceramic and UAE ranges, then order the compatible bottom bracket for your riding needs.
