Augusto’s aero road disc special

This was a fun build! Augusto started out requesting an aero road build, but with disc brakes since he lives in the mountains. Then with a bit more pondering, he decided he wanted a more unique look, so asked if I could add twin toptubes/seatstays to the design. This worked out nicely as also giving a clean way to route the rear hydraulic hose and Di2 wires to the back of the bike.

The frame has a custom butted, ovalised integrated seatmast, a Columbus aero downtube, and Deda s-bend chainstays. The custom fork has airfoil section blades, with a post-mount for the disc caliper and internal routing through the steerer. The matching custom stem includes a boss for the Di2 control box.

For parts we have Dura-ace Di2 for the shifting, with an FSA K-Force light crankset. Shimano R785 shifters operate the XTR brake calipers on 140mm rotors, which are mounted on Reynolds Attack wheels, shod with Schwalbe 25C tubeless tires.

The fantastic two-tone paint was applied by Colorworks, and includes Augusto’s own logo on the seatmast. Total weight as shown is 18lbs.

  1. Very slick look.
    Funny you mention aero bike to twin tube “fastback” design – I was thinking the same thing when I first saw the earlier 29’er build – ease of running Di2 wires (among other reasons). But decided I need the folding system and rim brake.

  2. Oh my God this is fantastic. Cool component selection too!

  3. I would like to know who is Augusto? Could you please tell me the full name of the designer? Thank you.

    • Augusto is my customer and the owner of the bike – the bike was designed and built by me, Rob English of English Cycles.
