The new MASON SLR [SuperLongRange] steel bicycle is the result of our focus on smooth, long-lasting performance, and luxury grand-touring capabilities. A new chapter in Mason Cycles’ obsession with high performance steel, designed in collaboration with one of the most skilled and established bicycle frame builders in Italy.

To celebrate the release of this very special frameset, we are making a limited collection of 10 ‘Launch Edition’ frames in 2 exclusive metallic colourways, finished with polished stainless steel badging and ‘Launch Edition’ decals.
Pre-orders for the 'Launch Edition' framesets are now open. You can use the button link below to request more information, make pre-order enquiries, and view the fine details and design features of the class-leading MASON SLR frameset.


Images show an unpainted, final prototype frame. Production frames will be painted in colour ways shown in the full details attached.

The capacity for 700C x 40mm tyres, including full fenders, and multiple attachment points for accessories and carriers gives the SLR wide ranging, all-condition, and long-distance capability - from refined grand-touring to fast cross-country and multi-day adventures.

The SLR tube set makes for an engaging and comfortable ride with an emphasis on smooth, fast travel. The custom shaped, progressively-butted, phosphate-coated Dedacciai Zero/Zero Uno tube set is made exclusively for the SLR frame. It offers class-leading compliance and weight, combined with a propulsive, plush ride quality, and maximum pedalling efficiency.

The Launch Edition (LE) frames will be presented in 2 exclusive colourways:

DarkRoom Red metallic, a subtle deep red that shifts almost to black in some lights, and comes to life with the sunlight.
DiffuserBlack Metallic, a very fine mica metallic, with hints of bronze in the sunlight.

Each very special ‘LE’ frameset is finished with additional polished stainless steel badging and ‘Launch Edition’ decals. Each frame will be stamped with a special ‘LE-1>10’ frame number and will come with a ‘Launch Edition’ gift pack, including certificate signed by the welder and designer, a LTD Edition MASON T-shirt and an exclusive MASON Keyring.

Paired with a brand new full-carbon fork - RangeFinder AR [‘AR’ for AllRoad] - which is tuned for all-road riding conditions. The RangeFinder AR features a set of molded-in eyelets which are designed to be fitted with a front rack or rando-style bag support, in addition to an internally-routed dynamo front light.
