Gutter Seal Technology drastically improves sealing against the elements while reducing seal drag. SRAM also designed a fresh cup forging for a high-end look. The SRAM GXP team bottom bracket sets a new standard in external bearing performance. Technologies: GXP: Giga X Pipe External Bottom Bracket Bearing Assembly. While other systems rely on side loading the bearings to eliminate play, which causes premature bearing wear, the GXP system is different. The GXP system captures the left side bearing between the spindle and the left crank arm while allowing the drive-side bearing to float axially on the spindle, thereby eliminating the necessity to side-load bearings during adjustment. The simplicity of installation is refined: once it is tightened to the proper specifications you are ready to roll with a worry free BB. The GXP system uses two bicycle specific cartridge bearings and eight seals for a smooth and long-lasting ride.
Pressfit BB to convert PF30 to BSA threaded
Utilising SRAM's Dub bottom bracket technology, this BB has a 28.99mm crankset spindle/inner bearing diameter and benefits from BB30 lightweight bearings and strong crank spindle for an efficient, integrated drivetrain performance. As durable as SRAM's 24mm bottom bracket systems, this model allows for a low-maintenance, high performance rotation of your crankset.
Featuring an integrated seal that’s pre-assembled into the cups, SRAM’s PressFit 30 bottom bracket is designed to keep out dirt and water that could cause increased wear and tear. Simple to fit, it is designed for road and mountain bike (MTB) frames with bottom bracket shells with a 46mm inner diameter and cranksets with 30mm diameters. The key difference with PressFit 30 is how the bearings are fitted into the frame. Bearings are housed in nylon cups which will be pressed into the frames bottom bracket shell. This bottom bracket is designed for 30mm spindle cranksets. Frames will need a 46mm inner diameter bottom bracket shell to accommodate this system. PressFit 30 for road will require a 68mm wide shell while PressFit 30 for MTB will require a 73mm wide shell. When designing the SRAM PressFit 30 bottom bracket, the brand set out with the aim of combining the best of BB30 technologies with the best features of the Pressfit standard. The result of this is a sealed 30mm bearing system with superior bearing life. Manufacturer's Part Number: 00.6418.009.000
Can Fit Any Frame Standard The SRAM DUB bottom bracket does not introduce any new frame bottom bracket standards or specific's that must be adhered to in order to get the performance benefits. The DUB system can fit any frame standard and enables the use of the SRAM Eagle DUB cranks with these frames. More Durable & Larger Bearings Compared to 30mm (BB30) & Lighter than 24mm (GXP) The DUB system cranksets use a 28.99mm diameter spindle, which is significantly smaller than the current BB30 standard, enough to enable the use of larger bearings and substantially greater seals. On the flip side of the design adjustment, this new bottom bracket system is as durable as the superb SRAM GXP system but is also much lighter. The 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, SRAM engineered the DUB spindle to be the one true unifying component. One oversized spindle to work across every bottom bracket specification. For better crankarm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler. Now, back to the ride. The DUB bottom bracket system is the bearing setup from SRAM that is compatible with all frame bottom bracket standards and is compatible with SRAM DUB range or cranks. The SRAM DUB threaded bottom bracket finds the perfect balance between weight, strength and durability.
