Avian BB86 Press-Fit Bottom Bracket — designed for frames with a BB86 shell (86mm wide, press-fit). Available in three versions: sealed bearing with composite cups (the lightest), ceramic bearing with composite cups (lowest friction for maximum power efficiency), and sealed bearing with alloy cups (most durable). If your frame runs BB86 and you want a reliable, correctly specced replacement or upgrade, these are purpose-built for it.
Options
- Composite Cups / Sealed Bearings — lightest option
- Composite Cups / Ceramic Bearings — lowest rolling resistance
- Alloy Cups / Sealed Bearings — most durable
Avian is a MoJo BMX brand. BB86 is a press-fit standard — installation requires a press tool or professional installation. Confirm your frame's BB shell standard before ordering.
