Ultegra R8100 Di2 Complete Bike

Regular price $7,750

Ask us to pick a drivetrain to pair with the balanced, race-tuned characteristics that define the new ALFA. We’ll tell you it’s Shimano’s Ultegra R8100 Di2, and we’ll insist on complementing the union with ZIPP’s 303 Firecrest wheels. And we wouldn’t even have to think about it, because we’ve been thinking about it for over two years while dialing the ALFA as the perfect, all-around road racing bike – a descriptor that applies just as well to Ultegra and the 303 Firecrests.

Now ask us what makes an all-around racing bike perfect. We’ll tell you it’s balance. And that’s what the ALFA does – balances aerodynamics and weight, stiff efficiency and chatter-damping comfort, traditional frame lines with intuitive, reactive handling only made possible through our decidedly non-traditional carbon fiber expertise. So yeah, balance.

  • A balanced road racing machine, built-up with an all-around Ultegra and ZIPP 303 Firecrest kit.
  • Finished with a Black Inc. handlebar and Cane Creek headset.
  • Engineered and refined to eliminate any gaps in performance. Climbing, aerodynamics, pedaling efficiency, and intuitive handling – the ALFA is the ultimate racing bike.
  • US-made, aerospace-grade Mitsubishi carbon and resin, with every piece cut, stacked, and formed right here, by us, in the ALLIED Technology Center.
  • Aluminum and titanium finishing components machined in-house for tighter tolerances, more reliability, and greater longevity.
  • Developed and tested in-house with internal methodology and machines.
  • Included ALFA Stem is fully integrated with the fork, supports internal routing, and reduces stress on handlebar and steerer.
