ABEC-7 Steel Bearings: Crafted from SAE 52100 chrome steel, our BBInfinite ABEC-7 (ISO 492, Class 4) bearings are so buttery that you’d have to buy our Ceramitechs to find anything better. These bearings feature mid-contact seals for extreme performance and durability. Each bearing comes lubricated with Kluber or Koyo. 1-Year Bearing Exchange Warranty.
MORE THAN EXTREME SPEED AND SILENCE:
BBInfinite DirectFit Shimano bottom brackets maintain optimal chain-lines for crisp, consistent shifting and drivetrain performance. Duel polymer bearing shields seal out dirt and debris while isolating the steel crank spindle from the steel bearing races to eliminate a major source of creaking.
POWER METER FRIENDLY
All BBInfinite DirectFit Shimano bottom bracket modules are 100% compatible with all crank-based power meters.
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.
INSTALLATION IS A SNAP WITH BBINFINITE:
Every BBInfinite module ships with the special press tools, hardware, instructions, and the retaining compound you need to get the job done correctly with ease and confidence. All you need is the press for this road bike bottom bracket.
