Power meter options for track bikes are very limited, and the Dura Ace Stages power meter<\/a> is one of the most reasonably priced and simple to use on the market. \u00a0Based on the Dura Ace 7710 Octalink platform, the Stages power meter offers a simple, elegant power measuring solution for fixed gear bikes. \u00a0Painstaking refinement has gone into the algorithm used to calculate power to meet the unique demands of a fixed gear bike, improving performance and reliability in data recording.<\/p>\n

Check out the video of the installation, re-posted from Periscope<\/a>. \u00a0Throughout the installation, there's a little bit of Q&A about power meters based on questions from live viewers. \u00a0Click through the jump to watch the video and check out the video show notes:<\/span><\/p>\n
