Surly Dual Speed

Surly Niner Dual Speed

While I’m suffering from mild sunburn after spending a weekend on the beach, I’m mindful to remain grateful—in Wisconsin, there’s snow and zero degree temperatures. Which means little riding, but here’s the perfect vehicle to tackle the local trails once the snow begins to melt. Mark built himself a Surly frame with a Niner fork and, rather than remaining constrained by a single speed configuration, applied a front derailleur to achieve a dual speed setup.

Mark’s original intention was to create a hybrid townie and cross bike, and was successfully ridden as such for a while. Eventually the call of the wild was answered and the Surly evolved into the dual speed arrangement you see here. After much tinkering and tweaking, a derailleur was sourced that could handle the jump between the 32 and 22 tooth chain rings. An 18-tooth sprocket on the rear provides Mark’s ideal ration: 32/18 for cruising, 22/18 for climbing. A Paul Components Thumbie restores the thumb action shifting, while a Melvin provides the necessary tension. Mark splurged on the Hadley hubs but assures us they’re worth every penny as they’re the smoothest rolling hubs he’s ever experienced.

    Excellent. I love Surly bikes. I commute on a single-speed Cross Check. I may just have to build up a Karate Monkey for mountain duty. This build is inspiring. Just gorgeous and the black/white theme is dynamite.

    Damn, so I’m not the only one to have this idea. I’ve been running my XC bike as a 3×1 for a month. A Shimano Afline tensioner (CT-S500) with provide adequate tension for 44/32/22 gearing up front.

    Why not simply run one chainring along with a derailleur in the back, eliminating the need for a chain tensioner? I admit that the simplicity of two choices in gearing does appeal to me. Regardless, those gold accents are really growing on me. Can’t help but thinking a round-blade fork would look even better with the Surly.

    Great detail with the cut outs on the rear sprocket, amazing. Who is the manufacturer? Great job on the build

    I like this funny looking bike & it’s blingage.
