Specialized Power Meter Shimano Ultegra Upgrade Kit

Simple. Lightweight. Accurate. Everything you need from a power meter that doesn't cost the world. Specialized have come up with an ingenious design by utilising Shimano Ultegra's left arm crank making it compatible with their power meter device. Validated by the Locomotion Lab, the cranks have been proven to provide only a 1.5% difference which at £400 makes it one of THE most competitive power meters on the market in relation to accuracy. Compatible with all devices using ANT+ and Bluetooth® devices including Garmin and Wahoo, it's difficult to find a reason why you would choose any other single crank power meter. Specialized have ensured their design is waterproof and leads the way in temperature compensation firmware as well as coming nicely finished with a wrench to make battery swapping easy and hassle-free.
