Merlin ROC Disc Road Frameset – 2018


The Merlin ROC Disc road frameset 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 frameset will build into the type of aggressive, hard-wearing road bike that 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 frameset is ready to sport mudguards making it the perfect option for a wet weather road bike build. 

The Merlin ROC Disc frameset features a light but durable 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 is designed specifically for disc brakes, with the frame featuring flat-mount fittings for a sleek, uncluttered look.



  • Frame: Triple-butted 6061 Series Aluminium, Q/R rear dropouts, 135mm spacing
  • Fork: Merlin Disc with carbon blades, flat-mount disc fitting and alloy steerer, Q/R dropouts
  • Internal gear cable routing
  • Internal disc brake hose routing
  • Flat-mount disc fitting for neater look
  • Internal headset included
  • Max tyre clearance - 35/38mm Gravel Tyre (without mudguards fitted)

Geometry & Sizing




Martin Chico California USA This is generally a very good frame for my purposes; I've built into a nice 4-speed, "town bike" with mostly used and/or vintage parts. I paid about $270 U.S. for the aluminum (alumininium) frame, the carbon fork and integrated, sealed bearings. I think that just about any comparable package would be in the US$400-US$500 range. The colors are beautiful and the finish is generally very good. I only have two small complaints that preclude me from leaving a 5-star rating: (1) There is a welding and/or paint "glitch" in about a 5-10mm area on the drive side chain stay. It's right on top of the chain stay, so it's very obvious. (2) The cable routing boss for the shift cable is quite a bit outboard - so much so that it brings the shifting cable to within 2-3mm of the (172.5mm) crankarm. A longer arm might just hit the cable. In any case, the cable runs 10-15+mm outboard of the chain stay, and I fear it will be easy to catch on something. (I have pictures, but I don't seen an option to provide them here.)
TRENT Great looking frame. Bought it for a custom build gravel bike. Frame is better than pics. Cant wait to ride it
