The Magene Ridge Shimano Ultegra R8000 single sided power meter. A direct measurement strain gauge based power meter that’s cheap, reportedly accurate, and kind of accessible…. ‘Kind of’ as you won’t typically find them in your local bike shop unless you’re in China. Here’s my take on the unit and the data after a few 100kms of use indoors and out. Please SUBSCRIBE to support this YouTube channel:
