The SRAM S300 puts the precision of PowerGlide shifting technology within easy reach. PowerGlide also gives you enhanced tooth profiles for quicker shifting and more precision. The crank arms are forged out of our AL-6061-T6 alloy material with a design that is beautiful, strong, and light. The addition of the Giga X Pipe™ offers a legendary and durable bearing design in a lightweight package. The SRAM S300 is available in both full-size and compact ratios and in multiple crank arm lengths.
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.
