American Custom Bicycles in Steel, Titanium and Ti/carbon mix
Both the BB30 and Press Fit 30 bottom brackets are available as options on all of our frame models.
These are terms for two new standards of oversized bottom bracket shells that use 30mm spindle and direct-fit bearings, or bearings housed in cups, that are pressed into the frame’s bottom bracket shell.
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.
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.
The additional charge for this option is $295.
