No Ordinary Gravel Build for No Ordinary Frame Design

“Leaning heavily towards Gravel Monster Cross, this build offers a mix of MTB and Gravel components to ensure dirt-worthy adventures. From the custom Boost 29’er Wheelset to the Supa-Wide Drop handlebars we wanted to ensure both comfort and control for heading into the hills and charging the singletrack.” –

“Designed around a 490mm to 510mm axle-to-crown fork, the bike can handle either a rigid fork or a modern suspension fork. We kept the build more DIRT by opting for the sublime Fox Transfer Dropper (complete with Kashima Factory coating) and a 180mm front rotor. Strap on some bags and lights and this would make one very fun and comfortable bike packing rig!”

Some obvious points, this frame design is similar to some old-school BMX frames and the dual downtube design is inspired by both those BMX models as well as motorcycle frames that date back way more than three decades. Keen-eyed readers around cycling over 25+ years will also notice a resemblance to the Colnago Carbitubo road frame, one that was actually built by Alan of Italy.

“When you delve deeper into the details, you will realize that whilst inspired by the past, you look at the market today, there is really nothing like it currently available.”

“For starters, this is a full-blown 29’er off-road bike that was designed with modern MTB frame geometry and bike standards.”

    Wonderful… so now the animal poo thrown up by the front tire can have a direct line to the bidons rather than having to take that pesky dependency on splashes from the myriad of puddles, stream crossings, and mudholes we gravel riders are subjected to on the myriad of courses out on the open range.

      That was the problem I had with my Carbitubo, but on the road.

    Look up an SE Quadangle BMX bike, it’s basically the same design, came out in ’79.. even same color..
