Merlin Inferno Carbon Disc Road Frameset


The Merlin Inferno has been designed and built for out and out speed. Sprints, descents, time trial or triathlon this aero road frameset is ready to perform. The Silhouette of our new Inferno is dominated by the wide aerodynamic lower tube with its "Kamm-tail" shape and is complemented by lowered seatstays for even more efficiency in the wind, these ultra-thin seatsatys reduce air resistance while providing some compliancy for an even more comfortable ride. The seatpost on the Merlin Inferno can be rotated 180 degrees to allow you to dramatically adjust your fore and aft position on the bike making it ideal for time trialists and triathletes while the addition of flat-mounts for hydraulic disc brakes ensures braking remains predictable and consistent regardless of the weather and road conditions. The Merlin Inferno frameset features Thru Axles on the front and rear which ensures wheel location is always accurate and brake pads and rotors always align perfectly while also increasing stiffness and steering precision.

The Merlin Inferno frameset is compatible with mechanical and electronic groupsets; all cables run neatly through the frame tubes with the hydraulic cable for the front disc brake also running inside the front fork. 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 disc-brake aero road bike on the open road the Merlin Inferno frameset is a great chassis to build your dream bike up on.

Alex S. Great Frame set, just about fits 28mm tyres with a about 3-4mm left minimum. Pretty light but not the lightest, handles rough roads very well and I definitely feel better control and power transfer compared to my previous frame (Lightweight Alu ). I would recommend this frame set to a friend.
Mr Herrod Nicely built distinct frame easy to run the internal cables which is always a plus. You will probably want to run 140 mm rotors front and rear and you will need some 5M bolts to mount the rear disc.
Robert So far so good. Low, aggressive riding position. The frame stiff enough, maybe a little bit firm.? I build it with Sram red etap HRD to minimize the cables. I'll give 4 stars because no instructions how use shims, spacers and headset covers. That caused me a headache to eliminate the headset rocking. Otherwise can't go wrong if you choose this frame. The price really competitive. I noticed the caliper mount under the chainstay ( direct mount) and on the fork (normal mount)... Strange thing if you think this is a thru axle frameset so you can't really put in a rim brake wheel!? My bike came out just under 8kg in size large, but I used a light set of wheels.(1370g)
Gary Puttock Real value for money at £599 not sure at £1800! Be aware no instructions but pretty straight forward as the internal cable feeds are better than any other frame I've built. Ride is good. Bit harsh but its an aero frameset so comfort not on it's radar. Paired with some 50mm wheelsand aero cockpit it does shift well.
stanley First ride on my new Merlin Inferno today. Dressed it out with shimano 105 Hydraulic disc brakes, Zipp bar and stem, and a pair of Mercury wheels. This frame and fork are fantastic. Stiff, but not so much so that it beats you to a pulp on a rough road. Very responsive when you stomp on the pedals, and the handling is very quick. In my 40+ years of biking I've owned a lot of bikes, and I can honestly say this is one of the best.
