Built with SRAM Red AXS, this version of the ALFA DISC is our no-holds-barred configuration. SRAM Red AXS represents the absolute cutting edge in drivetrain technology. Its wireless shifting is all-but-telepathic, the braking is ultra-precise, its overall weight is SRAM’s lightest and its finish quality is the most mouthwatering. It comes paired up to Reynolds Blacklabel Aero 46 wheels and an Easton cockpit.
Our stock-in-trade here at ALLIED is gravel and we’re living in a cycling industry moment where versatility is the bike trait that matters most. That said, there is something gloriously pure about the single-minded road machine. The ALFA DISC is exactly that: Our knock-down, drag-out race bike whose goal is to take each and every one of your watts and transform it into sheer speed. The carbon layup and frame geometry are tuned with care to give you just the right amount of road feel for blasting through twisty roads. The final addition to its performance is actually subtraction -- the way we take the edge off the high-frequency chatter from choppy pavement.
The ALFA DISC pairs the very best in technology and performance to timeless design. We leverage the very best in raw materials and engineering know-how to deliver a best-in-class race bike, doing so in an elegant and pragmatic way.
Elegance? The near-level top tube of the ALFA DISC hearkens to decades of classic road bike aesthetics. We obsess on the little things like cable management and the seatpost binder. Pragmatism? We dismiss 15 years of senseless blather about new-and-improved bottom brackets and build the ALFA DISC with a 68mm threaded design. We offer the bike in 12 sizes -- including “+” sized headtubes. We use Innegra fibers at high-stress areas for added durability where you need it most.
