SRAM Red Black BB30 Chainset

Strong, smooth, responsive: the SRAM RED Crankset is the perfect choice. The integrated carbon spider’s design is sleek and incredibly stiff, allowing for efficient power transfer.
Supersize your ride with the BB30 SRAM RED Crankset: 10% more stiffness – more power to the pedal, 20% less weight, and 300% more ankle clearance.

  • The integrated carbon-spider construction is light and stiff for greater power transfer with less effort.
  • SRAM Red PowerGlide™ chainrings are designed to professional-grade shift, stiffness, and durability standards.

Technologies:

  • BB30: SRAM RED & 2010 SRAM Force have a SUPERSIZED option with BB30 crank & BB technology. 30mm axle + oversized in-frame bearings = a stiffer package than 24mm spindle applications – delivering more power to the pedal at a 20% weight savings. The elegant OS crank profile gives substantially more ankle clearance eliminating heel and ankle contact for floater pedal users. Available in 130BCD Standard and 110BCD Compact crank sets.
  • 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 crankarm 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: A variant of the external GXP bottom bracket, PressFit cuts weight by up to 40 grams and eases installation by allowing you to press the bearing cups into the frame instead of threading them. Requires no change to the crank spindle length and diameter.
  • Pressfit 30: This is a new design led by SRAM. It’s all the best from BB30 and Press-Fit bottom brackets in one captivating package. This bottom bracket is designed for 30mm spindle cranksets. 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. PressFit 30 will feature an integrated seal, pre-assembled into the cups, to further prolong bearing life. 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. Advantages: Huge weight savings, narrow Q-factor, more ankle clearance, greater bearing durability, stiffer/stronger crank construction, simple installation. Allows for larger diameter frame tubes increasing frame stiffness. Drawbacks: Still searching
