2015 Stages Hollowgram Cannondale SI Power Meter

One year old Stages Hollowgram Cannondale SI Power Meter. 175mm in length. New retail is about $800 now. Scuff marks from shoe and a few scratches on the end from pedal strikes on rocks. New battery and new battery cover along with most recent firmware update. Compatible with most ANT+ and Bluetooth GPS head devices. Will give you power/cadence with not wires. Works perfectly, just not racing anymore so I don't need it. Check stages.com for more info but will work with 2014 and newer SI and SISL2 cranks. Just take off the left arm, put this one on, pair it with your Garmin and you have power.
