Merlin Nitro Aero carbon frame built with the latest Ultegra R8050 Di2 groupset

The Merlin Nitro Aero carbon fibre road bike featuring Shimano’s brilliant Ultegra R8050 Di2 electronic groupset has been developed to be aerodynamic, super-stiff and responsive making it ready to race straight out of the box. Each tube profile and frame junction has been specifically designed and constructed to cut through the air more efficiently encouraging you to attack the bunch and hold your speed in an aerodynamic tuck. Our flagship aero frameset is available in a variety of configurations to suit your riding style and your budget; now the Nitro Aero Ultegra R8050 Di2 offers you all the benefits a contemporary aerodynamic road bike combined with the efficiency of electronic gear transmission.


The wind-cheating Nitro Aero frame and fork includes all the design-features you’d expect in a modern aero road bike including an aero profiled down tube, smooth integration from the fork crown into the frame head tube and down tube, an aero profiled seat tube and big boxy chainstays blending seamlessly into the large bottom bracket area for a super-stiff cockpit that enables you to transfer all of your power through the frame. Internal cable routing contributes to clean lines and an uncluttered silhouette while an aero seatpost specific to the Nitro Aero frameset fits seamlessly into the seatpost clamp.


The Merlin Nitro Aero doesn’t just hold its straight line speed well but also handles brilliantly on the open road and has been engineered to help you descend and corner in confidence. This agile bike keeps you comfortable too, with a small amount of compliance built into the seatstays you’ll feel encouraged to stay in the saddle longer while your average speeds keep on improving.




The Nitro Aero specification features a full Ultegra R8050 Di2 groupset showcasing the latest development in the evolution of the electronic groupset from Shimano. Taking technology from the Dura-Ace Di2 groupset while at the same time refining the previous version of their Ultegra Di2 groupset Shimano have tweaked the ergonomics of their Di2 shifters and included more shifting options to enable you to fine tune your setup to suit you. With a new Shadow Technology rear derailleur that gives a lower, more aero profile and increased protection from crash damage the Shimano Ultegra R8050 Di2 groupset marks a significant development in the evolution of Shimano’s Di2 electronic drivetrain.


A choice of Shimano or Fulcrum wheels and other great finishing components lets you customise the finer details of this great handling carbon road bike before our Merlin workshop technicians custom build your bike to your own spec. Choose your preferred tyres, stem-length, handlebar profile, cassette, chainring options and more to tailor your dream aero road bike specifically for you. Whether you want to beat the competition at your weekly crit race, are looking to improve your bike split at that upcoming triathlon or just want to enjoy the ultimate aero road bike on the open road the Merlin Nitro Aero Ultegra R8050 Di2 is the perfect bike for you.

Mr Claas Excellent! I was concerned that the geometry would be too stretched out but those fears were unfounded. I love this bike, very stiff and fast but vertically compliant. I took a chance buying online with no test ride but it has turned out to be a great bike. Di2 shifting is perfection.
