Merlin Nitro SL Carbon Road Bike – Shimano Ultegra Di2 68700 11 Speed Drivetrain

The Merlin Nitro SL Di2 is our superlight race bike weighing a helium light 7.70kg and featuring oversized tube profiles manufactured from extremely high modulus carbon. Lightweight and super-stiff at the bottom bracket the Nitro is extremely responsive and is ready to accelerate when you jump out of the saddle to sprint.

With weight saving and a clean, fuss-free design at the front of our minds we included some versatile dual purpose internal cable routing using the same holes for mechanical and electronic shifting resulting in a very clean look. While the Nitro responds quickly to your pedaling input thanks to its lateral stiffness there is also a small amount of flex engineered into the seat stays to increase vertical compliance giving some welcome additional comfort on longer rides.



Our carbon frame features an intelligently engineered mix of 60 / 40 / 30 Ton High Modulus Carbon and a full carbon fork. The Merlin Nitro SL has been fitted with the brilliant Shimano 11 speed Ultegra Di2 electronic groupset which takes gear shifting a whole new level, with each selection feeling light and precise - Ultegra Di2 gives you consistent, maintenance-free gear changing every time. Finishing off the package is a competent pair of Fulcrum Racing Quattro wheels.


Our best-ever-value lightweight carbon road bike has recently gained rave reviews from the cycling press….


Road CC Review May 2017 - Rated 4.5 / 5

"The ride is sublime, that balance of stiffness and the way it deals with the bumps in the road is a masterclass in carbon fibre layup and tube design. The Nitro SL just seems to take everything in its stride with regard to road surface imperfections. Merlin has played a blinder here, offering a race proven frame at such a great price..." - Full Review Click Here


Cycling Weekly Review 12 December 2016 - Rated 9/10

"The Nitro SL offers an interesting and rewarding mix of efficiency and comfort. You can feel the stiffness of the bottom bracket area and the rear triangle, it delivers the most tangible feel of efficient power delivery that I've encountered."

"Merlin has pulled off something of a coup by sourcing a frame ridden at World Tour level in 2016 and offering it as a great value package. You can feel the frame's racing heritage in its ride performance, but if delivers without sacrificing comfort... £1750 - It's something of a bargain." - Full Review Click Here
