Shimano is the pioneer of electronic shifting, and on this ALFA DISC build we feature their top-of-the-line Dura Ace Di2 9170 drivetrain. Shimano diehards swear by the low-profile Dura Ace shift levers, and who doesn’t love the stealthy metallic finish of each and every component? We marry it up with Reynolds Blacklabel Aero 46 wheelset -- featuring Industry Nine hubs -- 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.

And while we leverage the very best in raw materials and engineering know-how to deliver a best-in-class race bike, we do it 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.

The ALFA DISC pairs the very best in technology and performance to a timeless design in a classic silhouette.

Have a Question?

Timeless design

The top tube is nearly level, giving the ALFA DISC a classic look. And after more than a decade of changing bottom bracket standards, we happily use a threaded 68mm shell. No more creaking, easy to service and just as light as any other bottom bracket standard. Your mechanic will thank you.

Geometry

Fit is everything. The ALFA DISC is available in an industry-leading 12 sizes. This includes our plus-sized frames. The “+” designates a 2cm taller headtube that slightly raises your bars to allow for a more relaxed position.

Tire width

When it comes to high performance wheels, wider is indisputably better. The ALFA DISC accepts all modern rim widths so you can maximize your aerodynamic advantage. And when you’re looking for a smoother ride -- you can fit tire sizes up to 700x28c.

Cable Management

The ALFA DISC treats cable management as an essential detail of industrial design. We’ve designed the routing to be easily compatible with every drivetrain option out there. The cables look all-but-hidden, and installation and maintenance is a breeze.
