Flagship Aero Carbon Frame

The DA54 is made from high modulus carbon, tuned for stiffness and speed. Fully internal cable routing, an integrated handlebar and stem, and a matching full carbon fork give the bike a clean, uncluttered front end and an aerodynamic profile. The fork uses a 100x12mm thru axle, and the frame fits a 700C wheel setup. It’s available in five sizes: Extra Small, Small, Medium, Medium-Large, and Large.

Shimano Ultegra Di2 Electronic Shifting

The DA54 runs a full Shimano Ultegra Di2 2x12-speed groupset, including the ST-R8170 shifters, RD-R8150 rear derailleur, and FD-R8150 front derailleur. Electronic shifting is fast, precise, and consistent, with no cables to stretch, so every gear change is crisp whether you’re sprinting, climbing, or riding a steady pace. A Shimano FC-R8100 crankset (52/36T, 165mm to 172.5mm) is matched to an 11-34T 12-speed cassette, giving you the range to tackle steep climbs as well as fast flats, and a Shimano CN-M8100 chain completes the drivetrain.

Hydraulic Disc Braking

Shimano Ultegra BR-R8170 hydraulic disc brakes provide strong, controlled stopping power, with good modulation for fast descents, wet roads, and tight group riding.

Carbon Wheels Built for Speed

Helux R60 carbon rims on Alvas 1001 hubs (24 spokes front and rear, 100x12mm front and 142x12mm rear with an HG driver) give the DA54 a lightweight, aerodynamic wheelset. Pillar PSR Aero spokes add stiffness and a low drag profile, and Continental Grand Prix 700x28C folding tyres bring proven grip, comfort, and speed.

A Cockpit Made for Long, Fast Rides

The Alvas HL-HB02 integrated handlebar and stem is available in 38 to 40cm widths, for a clean, stiff front end. An Alvas HLSP-R05 carbon seatpost (280mm on the S, 350mm on the M, ML, and L) and a Selle Royal saddle complete a setup designed to keep you comfortable on long days in the saddle. A Senicx T47 bottom bracket keeps the drivetrain smooth and easy to maintain.

Backed by over 40 years of family owned expertise, every Alvas DA54 from bikes.com.au comes with 12 months of unlimited servicing and extended warranty, so you can ride fast with total confidence.
