JUST THE FACTS:
We’ve eradicated the dreaded BB30 CREAKS from BB30A bikes once and for all by eliminating the problematic bearing-direct-in-frame set up that has always been BB30’s downfall. Bike manufacturers are not able to hold the precise tolerances necessary to fit bearings into frames properly, resulting in poor performance, short bearing life, and the noises that let you know the bearings are dying with each pedal stroke. By completely replacing this flawed set up with one of our legendary one-piece, precision BB30 bottom bracket modules the frame is no longer in the equation and you will at last enjoy the benefits of silence, durability, and buttery smooth power delivery that many thought impossible in a BB30 bottom bracket system. Don’t settle for good-as-new when you can have better-than-ever with BBInfinite.
The BBInfinite BB30A-30 Mountain Bike Bottom Bracket Module works with most 30mm spindle crank sets on the market such as the FSA K-Force cranks, Rotor 3DF cranks, Cannondale Hollowgram Si/SL’s.
All of our modules ship with the special press tools and retaining compounds you'll need. All you need is the press to install this bicycle bottom bracket.
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.
WS2 Coated Ceramitech Bearings: We took our amazing Ceramitech bearings and added an extremely durable, tungsten disulfide (WS2) coating that has a 0.03 coefficient of friction---which means it’s slicker than Teflon, graphite, and even molybdenum disulfide. WS2 has an affinity for oils and greases, which means it maintains a hydrodynamic layer of lubricant where it’s needed most. The result is astonishing spin performance and increased endurance. These bearings feature mid-contact seals for extreme performance and durability. 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 durability. Each bearing comes lubricated with Kluber or Koyo. 1-Year Bearing Exchange Warranty.
MORE THAN EXTREME SPEED AND SILENCE:
BBInfinite bottom brackets for 30mm spindle crank sets maintain optimal chain-lines for crisp, consistent shifting and drivetrain 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 that unitizes the bottom bracket structure to eliminate all potential creaks before they start, every aspect of our arcitecture fuses beauty with durability and performnace.
Our 30mm spindle optimized design is set to the widest stance the crank set 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
All BBInfinite bottom brackets for 30mm spindle crank sets are 100% compatible with all crank-based power meters. Our flange-less drive-side arcitecture 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:
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. If you need a press, check out our Master Tool Press.
