    • JUST THE FACTS:

      BBInfinite's 29mm Specialized OSBB PressFit module works with all DUB road crank sets on the market. All of our modules ship with the special press tools and retaining compounds you'll need. All you need is the press. NOTE: OSBB PressFit is NOT the same as OSBB. OSBB Pressift is 46mm x 61mm. OSBB is just BB30 (42mm x68mm) by another name.

    • ABOUT OUR BEARING CHOICES:

      Ceramitech Bearings: Our Si3n4 hybrid ceramic bearings feature ultra-spherical silicon nitride balls matched to SAE 52100 chrome steel bearing races that have been processed with additional heat treatment and polishing steps. The result is a hybrid-ceramic bearing that lasts longer than any steel bearing with spin performance no steel bearing can rival. We’re so confident in the durability of our Ceramitech bearings that we back them with a Lifetime Bearing Exchange warranty. These bearings feature mid-contact seals for extreme performance and endurance. Each bearing comes lubricated with Kluber Isoflex Topas NB52. Lifetime warranty.

      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 endurance. Each bearing comes lubricated with Kluber or Koyo. 1-Year Bearing Exchange Warranty.

MORE THAN EXTREME SPEED AND SILENCE:

BBInfinite DUB modules maintain optimal chain-lines for crisp, consistent shifting and drive train performance while dishing out trouble-free mile after trouble-free mile. From the gorgeous, high-luster of our TypeII MilSpec hard anodized finish, to the sculpted lines of our One-Piece Design, every aspect of our architecture fuses beauty with durability and performance.


 

Our DUB spindle optimized design is set to the widest stance the crank format allows while ensuring that interfaces between crank arm splines and spindle splines have maximum engagement and Q-factor is set as narrow as possible.

POWER METER FRIENDLY

This DUB bottom bracket module is 100% compatible with all crank-based power meters. Our flange-less drive-side architecture ensures zero interference with protruding power-meter back plates such as those found on Quarqs and SRMs.

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:

All BBInfinite OPD bottom brackets ship 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. If you need a press, check out our Master Tool Press.
