Model Number: X9-FG

Please select options before adding to cart

For SRAM mountain riders we offer a Stages Power meter available as a power meter only non-drive crank arm for existing SRAM GXP systems. Riders looking to add power to their existing GXP crank will need only to select length to retro fit a Stages Power meter.  

All of the current inventory of SRAM X9 units will have our new Stages Power meter housing which is slimmer, and up to 28-percent lower profile than our original meter. It's sleeker by way of a 17-percent reduction in frontal area, and we've also made it stronger. The new housing design increases the strength of the battery door and housing connection by 200-percent over the previous design.
(Note: X9 GXP is compatible with X7, X9, X0, XX [166 Q model], and many Truvativ GXP models)
