Bottom Brackets

Bottom Brackets are an essential part of the bicycle that is often overlooked and forgotten, but we saw the BB as another opportunity for performance gains and improved efficiency. For our BB we have developed a seal that achieves a very low level of drag while still retaining excellent protection qualities. Its thinner and low viscosity bearing grease with the correct fill level offers higher durability at high speeds. If you're running the best crankset on the market, you should have the performance BB to match. - Thinner and lower viscosity bearing grease for higher durability at high speeds - In-house testing procedure includes developing a 24-hour continuous water invasion test - Offered in a variety of types for better compatibility - 386 EVO 46mm Press fit, 30mm Spindle, 103gm, 86.5mm

The new SRAM DUB bottom bracket series has a simple job: connect your crankarms and protect the smooth, long-lasting application of power to your drivetrain. To allow that singular focus, we've engineered the DUB spindle to be the one true unifying component. One oversized spindle to work across every bottom bracket standard. For better crankarm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler. Now, back to the ride. - One oversized spindle to work across every bottom bracket standard - Gutter Seal Technology drastically improves sealing against the elements - Significantly lighter than GXP system - Sealed cartridge bearings
