JUST THE FACTS:
The BBInfinite BB30 MTB DirectFit GXP bottom bracket module works with all GXP mountain bike crank sets on the market, from Sram, Truvativ, and all others. Every BBInfinite module ships with the special press tools and retaining compounds you need to get the job done correctly with ease and confidence. All you need is the press for this road bike bottom bracket.
MORE THAN EXTREME SPEED AND SILENCE:
BBInfinite DirectFit Gxp bottom brackets maintain optimal chain-lines for crisp, consistent shifting and drivetrain performance. Our BBInfinite OPD architecture freed us to delete superfluous wave washers and shims that pre-load bearings unnecessarily, causing drag and poor performance.
Our Gxp optimized design is set to the narrowest stance the crank set allows. This ensures that the interface between the non-drive crank arm and the spindle has the maximum amount of spline engagement.
POWER METER FRIENDLY
All BBInfinite DirectFit Gxp bottom bracket modules feature a flange-less drive side architecture for maximum clearance for power meter back-plates like those found on Quarq and SRM cranks. This flange-less feature is especially noticeable on non-power meter fitments with a typical 2-3mm of spindle showing. This is normal and optimal.

WHY DO BBINFINITE BOTTOM BRACKETS SPIN LIKE CRAZY?:
Bicycle frame bottom bracket shells are notoriously misaligned, inconsistent, and out of round, and so it’s inadvisable to use the bike frame as the primary aligning member for bottom bracket bearings. Yet, that’s what our multi-piece bottom bracket competition does, and this explains why their systems frequently fail prematurely and creak.
A BBInfinite OPD (One-Piece-Design) bottom bracket module is a CNC precision-machined hub---like the front wheel hub on your bike---that you press into your frame. And just like your trouble-free wheel hub, BBInfinite OPD bottom brackets have perfectly aligned bearings regardless of your frame’s BB shell alignment and tolerances. Perfectly aligned bearings are essential for thousands of miles of trouble-free use and extreme spin performance.
WHAT KEEPS BBINFINITE BOTTOM BRACKETS FROM CREAKING?
BBInfinite OPD is the answer for creaking bottom bracket problems as well. Pedaling forces conspire to lever, and rock, and eventually work multi-piece systems loose. The unitized nature of BBInfinite OPD cancels these forces out entirely, which means creaking has no place to start in the first place. It really is that simple.
