Merlin ROC Road Bike 2017 – Shimano 105 11 Speed Drivetrain

The Merlin ROC is our best ever aluminium road bike; with aluminium enjoying somewhat of a resurgence over the last few seasons we recognized the benefits of a simple, lightweight, modern alloy frame. Triple butted with slender rear stays, an elegantly triangulated top tube and a tapered head tube up front the ROC really is testament to the amazing yet affordable things that can be done with aluminium these days.

The versatile ROC road bike is like two different bikes in one neat package. Capable of providing you with long, comfortable miles in the saddle but stiff and responsive enough to encourage you to get out of the saddle and sprint for the finish line of your local mid-week crit race.



The Merlin ROC road bike features a lightweight triple-butted Hydroformed 7005 series aluminium frame and a carbon fork along with a full Shimano 105 11 speed groupset to provide dependable, precise shifting and powerful, confidence inspiring braking. We have completed the bike’s specification with a pair of Fulcrum Sport wheels and Deda components.

Krasimir I have had only XC and city bikes so far. My first impression from Merlin ROC 105 is like I am a rocket . The bike is light, fast, comfortable and easy to ride.
Mr Thomas Great bike, comfortable and fast. Paintwork looks really nice too. No frills from Merlin but great service and no problems. A couple of small bits were missing initially but this was very quickly put right-Many thanks
Mr Howell Lovely frame, quality finishing kit and groupset. Cracking value too! Wheels are basic but functional and you can always upgrade if you want.
Mr Mitchell Absolutely beautiful bike, well built, light and a very comfortable ride!!
Mr Latham Fantastic bike. This is a very light bike and well set up. I had this shipped to Spain and it was well packaged around the wheels and gears.. Pre shipping it had obviously been checked as on arrival after a quick build it was ready to use. Gears were indexed properly and brakes only needed minor adjustment. On the road the bike is sturdy, light and a dream to ride.
