Merlin ROC Disc Ultegra Road Bike

The Merlin ROC Disc road bike featuring a Shimano Ultegra 11 speed groupset and hydraulic disc brakes is a highly versatile, efficient all-rounder that takes the braking surface away from the rim of the wheel and enhances tyre clearance within the frame enabling you to fit up to 30c width tyres with room for a full mudguard or a 35mm gravel tyre with no mudguard.

This type of versatile all-weather, mixed-terrain road bike has really caught on over the last few years for obvious reasons. With fatter tyres and enhanced clearance between tyre and frame you don't have to stick to smooth tarmac roads; with a full complement of mounts the bike is ready to sport mudguards making it the perfect wet weather road bike. 

The Merlin ROC Disc features a triple-butted 6061 Aluminium frame with a comfortable, confident geometry that encourages all-day riding, a carbon fork that stops the ride feeling too harsh when you’re on the ruff-stuff and quality Shimano hydraulic disc brakes that deliver consistent, controllable braking in all weathers and riding conditions. A dependable, precise shifting Shimano Ultegra groupset with wide-ratio gearing completes the package.
