JUST THE FACTS:
Our DUB BB92 Pressfit module works with all DUB mountain bike 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. BB92 is also known as PressFit92, and the frame bottom bracket shell measures 41mm x 92mm.
Why would I choose a 2-Piece bottom bracket system?
Our 2-Piece Bottom Bracket system is for any bike that cannot accommodate our 1-piece unit. What would cause this? Easy; any obstruction that cannot be removed which prevents our 1-piece module from passing from one side to the other in a straight line through the frame bottom bracket shell, which includes:
1) The presence of a hydraulic line that cannot be moved out of the way.
2) An immovable fixture, hump, frame feature, or cable guide.
3) Any wires that cannot be moved out of the way entirely.
Over 90% of the bikes out there can use a 1-Piece module. If you are unsure please email us with the year, make, and model of your frame, along with the crank set model and type, at info@bbinfinite.com, and we’ll get you sorted.
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 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.
