Seven now offers the BB30 oversized bottom bracket option. This new international standard is available as an option on all of Seven’s current titanium and steel frame models.

What is BB30?

BB30 is the term for a new open standard of oversized bottom bracket shell that uses a 30mm spindle and direct-fit, pressed-in bearings.

Why would someone consider BB30?

The design eliminates the use of external cups that are threaded into the BB shell to hold the bearings, reducing both overall bike weight and the q-factor of the pedals. The larger bottom bracket shell also accommodates a 30mm spindle, instead of the more common 24mm spindle. This translates into increased drivetrain stiffness.

Is the BB30 68mm option compatible with my current 68mm English threaded bottom bracket?

No, this new standard requires the use of a completely different bottom bracket from our standard offering, so there are no parts that are compatible with both standards.

How much does the BB30 68mm option cost?

The additional charge for this option is $295.
