JUST THE FACTS:
The BBInfinite BB30A Road DirectFit Campagnolo is compatible with all Campagnolo UltraTorque road cranksets on the market, from Mirage to Super Record. DirectFit means you can use the USB or Cult bearings already on your crank, or use the included bearing set, or upgrade to BBInfinite Ceramitechs for ultimate performance. All of our BB30A bottom bracket modules ship with the special press tools and retaining compounds you'll need. All you need is the press.
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 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 DirectFit Campagnolo bottom brackets set 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 architecture fuses beauty with durability and performance.
Our Campagnolo UltraTorque optimized design is set to the widest stance the crank set allows while ensuring that the Hirth joint interfaces have maximum engagement and Q-factor is set as narrow as possible. To ensure ease of maintenance over time, all BBInfinite DirectFit Campagnolo bottom brackets use the standard 6805N bearings specified by Campaganolo.
POWER METER FRIENDLY
BBInfinite DirectFit Campagnolo bottom brackets are 100% compatible with all crank-based UltraTorque power meters. Our flange-less drive-side architecture ensures zero interference with protruding power meter back plates such as those found on 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's one-piece 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.
