Argon 18 Dark Matter Apex AXS Jenson Exclusive Bike Adventure Starts Now The Dark Matter is Argon 18's do-it-all gravel platform, built to handle everything from a fast group ride to an unsupported ultra-distance race. The carbon frame clears a 45mm tire, and Argon 18's Topological Compliance System tunes the carbon layup tube by tube for a ride that stays comfortable over rough surfaces without going soft in the corners. Mounts for bags and fenders mean the same bike works for a stripped-down race day or a loaded multi-day trip. The fork even routes internally for a dynamo hub if you want to run one. This Jenson-exclusive build runs SRAM's Apex XPLR AXS drivetrain - a wireless, electronic 1x12 groupset with an 11-44T cassette and a 40T chainring, giving you real gearing range without a cable to stretch or contaminate over a season of riding. SRAM's own hydraulic disc brakes handle stopping duty with 160mm rotors front and rear. An FSA Team i23 wheelset wrapped in Teravail Cannonball tires at 700x42c rounds out a build that's ready for pavement, hardpack, and everything rougher in between.
