BB86 Bottom Brackets – Compatibility and Performance
Our selection of bottom brackets is intentionally limited to ensure optimal quality and focuses on products from the brands Rotor and Bikone. These bottom brackets are compatible with the following cranksets:
- Rotor and Shimano 24 mm
- Rotor 30 mm
- SRAM DUB
Quality Levels:
- Rotor Steel: A simple and cost-effective solution for reliable assembly.
- Bikone Steel: High-quality bottom brackets with improved seals and better smoothness, justifying a slightly higher price.
Compatibility with BB86 Frames:
BB86 frames, with a width of 86 mm and an internal diameter of 41 mm, require a press-fit bottom bracket to install a crankset. Here’s how to choose the right bottom bracket:
- For a 24 mm crankset (such as Shimano or some Rotor models): use a BB86 41/24 bottom bracket.
- For a 30 mm crankset (such as Rotor 30 mm): use a BB86 41/30 bottom bracket.
- For a SRAM DUB crankset: use a BB86 DUB (41/29) bottom bracket.
Compatible Frames:
The BB86 standard is featured on many carbon frames, including the following brands:
- Canyon
- Scott
- Giant
- Lapierre
- Bianchi
- Cube
- Ridley
- BMC

What is BB86?
BB86 is a press-fit standard with a 41 mm shell I.D. and 86.5 mm shell width for road frames. It’s common on performance bikes from Canyon, Giant, Scott, Lapierre, Bianchi, Cube, Ridley and BMC. Always measure your frame or check the manufacturer’s spec before ordering.
Designed for Shimano 24 mm cranks
These bottom brackets are built for Shimano Hollowtech II 24 mm road cranks (105, Ultegra, Dura-Ace). If you need the wider MTB shell (often called BB92 at 41 × 92), verify the shell width first.
Budget-friendly steel bearings
- Great value: OEM-style pricing with reliable sealing and durability.
- Everyday performance: smooth running for commuting, training and long mileage.
- Upgrade path: start with steel; move to ceramic later if you chase marginal gains.
Replacing Shimano references
This category curates steel-bearing BB86 units positioned to replace the following Shimano press-fit models:
- SM-BB71-41B — 105 / Ultegra press-fit BB86 (24 mm spindle).
- SM-BB92-41B — Dura-Ace press-fit BB86 (24 mm spindle).
For a broader technical overview and pros/cons versus OEM cups, read our guide: BB86 bottom bracket replacement (SM-BB71-41B / SM-BB92-41B) .
How to choose
- Confirm your frame: BB86 road = 41 × 86.5 mm. (MTB shells are wider.)
- Confirm your crank: Shimano Hollowtech II with a 24 mm spindle.
- Conditions: for wet/muddy use, prioritise sealing and serviceability.
Installation tips
Use quality press tools, clean the shell thoroughly, lightly grease or apply the specified retaining compound, and torque the crank to spec. Proper prep is the best defence against creaks.
