Installation Instructions:

IMPORTANT NOTES:

• Our Eccentric bottom brackets for BB30 frames will not work with frames that do not have removable c-clips in the shell. If your frame has a shell with a molded step that the bearings press up against, our EBB will not completely fit in to the shell.
• 73mm BB shells require the use of M6 x 80 bolts only. Do not use M6 x 75 bolts in 73mm BB shell, damage to drive side cup threads may occur.
• Do not install bottom bracket with the two bolts positioned above the bearing. Some carbon frames do not have proper internal support for the bolts to properly tighten to spec. As a result, the cups will not stay tight in the frame, and at worst, your frame may crack.
