Seven offers a wide array of bottom bracket shells in our frames. Our standard, for all frames, is 68mm English BSA , but as with every feature of your new bike, we will recommend the standards and technologies we believe will give you the best ride experience. By eliminating the use of external cups, this standard aims to reduce 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, increasing drivetrain stiffness. The 30mm standard requires the use of a completely different bottom bracket from than a 68mm BSA shell, so there are no parts that are compatible with both standards.
