KTMRevelator Alto Exonic
KTM's race all-rounder, named for climbing ('alto' means high) but refined in the wind tunnel. The third edition of the Revelator Alto arrived in 2022 with KTM's Tour de France team. The Exonic is the only build on the top Nano Premium Carbon frame; for 2027 it comes with a one-piece Vision Metron 5D cockpit, SRAM Red AXS with a power meter and Mavic Comete 45 carbon wheels.
