Choose the bottom bracket standard for your frame

• ✅ ✅ Match the press-fit shell: BB86 Road and BB92 MTB are separate frame standards; selecting the correct one helps ensure the unit seats in the intended shell.
• ✅ ✅ Use compatible 24 mm cranks: The listing specifies compatibility with Shimano-specification 24 mm crank spindles.
• ✅ ✅ Keep the assembly lightweight: The listed weights are approximately 95 g for Road and 96 g for MTB, giving a reference when comparing setups.

This component combines an aluminium-alloy body with a plastic dust tube. Check your frame’s bottom bracket shell dimensions and crank spindle before ordering; the Road and MTB variants are not interchangeable solely by appearance.

The item is a press-fit bottom bracket, not a crankset or bicycle. Installation requires the correct tools and frame fit; follow the bicycle and component manufacturer’s service guidance.
