The Dura-Ace BB-7710 is the perfect choice for the Urban Rider or the seasoned Track Professional.

With exceptional quality sealed bearings, the BB-7710 is the choice of many of the Japanese Keirin riders as the weather is less likely to get into the bearings thanks to Shimano's Sealed Bearing Technology.

These Bottom Brackets only suit FC-7710 Dura-Ace Track Cranks.

We are often asked if the BB-7710 or the BB-7700 is the best option, and the answer is pretty simple – Do you ride Track or on the Street?
Our handy breakdown below might help you make a decision too.

Unsealed bearings

Typically, for anyone riding fixed or on the street we always suggest and encourage the BB-7710 bottom bracket.
If you’re a Track rider and only using it on the indoor Velodrome, the BB-7700 is by far the fastest rolling option – when setup correctly.
