The new Mason Exposure is a revised steel version of their versatile Bokeh “continent crusher.” Preorders just opened up for 10 “Launch Edition” frames and the two production colourways. Learn more here…

Update: Mason has let us know that all of the “launch edition” frames are spoken for!

The new Mason Exposure is much more than just a steel Bokeh. Mason developed the Exposure for “fast, long-distance and multi-month adventure touring over very variable and unpredictable terrain.” And compared to the Bokeh, the Exposure has larger tire clearance (650b x 58mm or 700c x 50mm), mounts for full fenders, and even more mounting locations for accessories, racks, and additional bottle cages.

The Exposure is built up around a custom-shaped, butted, phosphate-coated Dedacciai Zero Uno tube set with a CNC machined Reynolds 631 headtube shaped exclusively for Mason. Italy-based Cicli Barco is fabricating each frame. Mason paired the frame with their new full-carbon fork, the RangeFinder AS, which has bosses for cargo cages, racks, and fenders. It’s great to see top tube bosses, loads of mounts inside the main triangle and under the downtube, plus bottle cage mounts on the seatstays.

The Mason Exposure comes in eight sizes (48-62), each specced with size-specific components like handlebars, stems, and cranks. Compared to the Bokeh, it has a slacker 70° head tube angle, 10mm more stack height, shorter reach, and marginally more bottom bracket drop. Mason claims these changes will provide stability, predictable handling when loaded with gear, and comfort over long distances.

To celebrate the launch of the Exposure, Mason is making a limited collection of 10 “Launch Edition” frames available for pre-order. They will be offered in 2 exclusive colourways: DarkRoom Red metallic and DiffuserBlack Metallic. Each limited edition 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 T-shirt, and an exclusive Mason Keyring.
