This stunning model uses a cold forging process & weighs in at less than 890 grams. 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 & 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 & eight seals for a smooth & long-lasting ride. Powerglide Chainring Technology: Starting out with raw 7075-T6 alloy plate, we stamp, coin, & CNC the rings to create a precise shifting whole. Coining shapes tooth profiles into designs CNC alone can't match, creating a stronger tooth by strain-hardening the alloy for superior durability. Stainless steel pickup pins give shifting longevity. Chainring-specific finishing technologies & laser graphics add durability & appeal.
