Bikone DCTech BB86-92 Oversized - Ceramic Bearings - SRAM DUB

Bikone DCTech BB86-92 Bottom Bracket (⌀41.05mm - Width 86.5 to 92mm) Pressfit Oversized with Ceramic Bearings - SRAM DUB Compatible (⌀29mm)

The Bikone DCTech BB86-92 Oversized Bottom Bracket - Ceramic Bearings - SRAM DUB has been specifically designed for frames whose bottom bracket housing has widened over time, a common occurrence on many Pressfit frames. Thanks to slightly oversized cups (+0.05 mm), this model guarantees a firm and play-free fit, thus extending the life of the frame and ensuring optimal performance.

Compatibility

This bottom bracket is only compatible with Pressfit frames that have had their inner diameter widened over time. It fits Sram Dub cranksets (29mm axle) and frames with a width between 86.5mm and 92mm, with a diameter of 41.05mm. For optimal compatibility, MTB cranksets should be mounted on MTB frames, and road cranksets on road frames.

Technology and design

Dual Cup technology relies on two perfectly aligned aluminum cups, creating a rigid central junction that eliminates unwanted noise and movement. The housing incorporates precision hybrid ceramic bearings (ABEC5 / P5 – 2RS) for smooth and efficient pedaling.

The cups are made of 7075 aircraft-grade aluminum alloy, T6-treated for increased strength and durability. The housing is fully sealed, with axial seals on the bearings and complete protection on all surfaces.

Guarantee

• Lifetime warranty on cups
• 3-year warranty on bearings
