The new Mason SLR is a high-performance steel touring bike with an emphasis on “smooth, fast cross-country travel.” Preorders just opened for a small run of limited edition frames in exclusive colourways. Check it out here…

Mason’s latest bike is the product of another collaboration with Italian bike builder Cicli Barco. The new Mason SLR is what they describe as “the result of our focus on smooth, long-lasting performance, and luxury grand-touring capabilities.” Like their recently announced Exposure, the SLR is built up around a frame-specific phosphate-coated Dedacciai Zero/Zero Uno tube set that they say offers an engaging and comfortable ride quality.

The Mason SLR is kitted out with full fender mounts, rack mounts, standard bottle mounts, and an additional set of bosses under the downtube. It’s paired with Mason’s new full carbon RangeFinder AR fork, which has mounts for bag supports or front racks, plus internal dynamo wiring. While the photos show a raw frame with beeswax finish, the production version will be corrosion treated, primed, and painted with two coats of paint and a thick coat of lacquer.
