After having made individual arms for Power2Max to mate to their own power metering spiders for a few years, FSA collaborated with the power meter maker to develop their own branded versions. FSA has been working hard in the last year or two to fill out their drivetrain line, tied-in with their road pro team sponsorship. So their new PowerBox Carbon power meter cranksets join the recently introduced K-Force WE and WE Disc groups to complete their top road spec offering. At the same time, an alloy version hopes to open up to the door to more OEM power meter specs, with a lower cost of entry. They’ve also taken the same tech and ported it over to a premium carbon trail riding crank, to give power metering capabilities in either a 1x or double form for mountain bikes looking to take their training up a notch.
