The SRAM XX D1 Left Arm & Spindle AXS Powermeter brings together an XX carbon crank arm (left) with the power-monitoring technology of an integrated spindle-based Quarq power meter. Track watts in real time on your head unit & analyse your power progress post-ride with this impressive data-mining tool. ...

Featuring oversized chainrings, CNC machined from 6mm 7075 aluminium blanks, they measure 2mm thicker than the competition. Unrivalled rigidity is achieved by an increased Bolt Circle Diameter (BCD) & a two-piece insert-moulded carbon composite construction. The XX Crank geometry provides a narrow 156mm Q factor, efficient chainline, & bevelled crank arms to maximize clearance, while the XX chainring gives lightning-fast & accurate front shifting, through an all-new, patented, mind-blowing performance X-Glide technology. Technology: X-Glide: Traditional chainring geometry forces a compromise between up & down shift locations, none of which have ideal timing. In fact, half of the possible locations are skipped on each crank revolution. The more shift locations you try to incorporate, the worse the timing compromise will be: either your chain jams, causing chain suck, or the chain just fails to shift & runs across the top of the rings until it hits the next shift location. X-Glide is the common denominator that gives XX it's unmatched shifting performance. With the X-Glide, all four upshift locations are identical & can be picked up by any outer link. The result? Up & down shift locations have perfect timing for an almost instant shift. ...
