Hakka MX Overview

The Hakka MX is our answer to the Swiss Army Knife.

It’s the bike we’d choose if heaven forbid, we could only have one bike. The Hakka MX is a gravel bike. It’s also a cross bike and a road bike. We’ve logged a few bike packing trips on the Hakka too.

With its ultra versatile geometry and 1000g frame weight, the Hakka MX is just as happy crushing the local club ride as is it is jumping barriers or camping out.


It's good to have options. With the Hakka MX, you can run road, cross and gravel friendly 700c wheels, or if you are into burlier backcountry exploration, go with 27.5/650b. With the Hakka MX, you don’t have to pick one tire option or the other. Our subtle sculpted chainstays give the frame clearance for up to 700 x 40c or 27.5 x 2.1” tires. 

Cable Routing Options Galore

No matter what drivetrain you prefer, 1x, electronic, or 2x, the Hakka MX has you covered. The frame has internal cable routing provisions for every drivetrain on the market, plus a dropper post. We’ve even included a slick Di2 battery mount inside the downtube.

Bottom Bracket

We’ve tried every bottom bracket under the sun and in the end, we haven’t found anything that’s more reliable than a threaded BB. Our Hakka features the T47 BB standard, which uses  30mm bearings enabling you to use the recent crop of lightweight cranksets. This is the best way to combine a threaded BB with 30mm spindle compatibility. It’s lightweight, quiet and durable, because no one likes a creaky bike.

Disc Brakes & Fender Mounts

The Hakka MX has flat-mount rear disc mounts and fits a 160mm rotor. There’s also a removable rear fender mount on the seat stays.


We offer two groups (Rival1 and Ultegra Di2), two wheel sizes (700 or 27.5"), 2 color options (fireball or coal), two rim material options (carbon or aluminum) and this image was too pretty not to include.


The Hakka comes in five frame sizes: 49, 53, 55, 58, 61

Notes from a Ramble

Chris McNally did the Ramble Ride Asheville last October on the unreleased at that time Hakka MX. Along with it, Chris did a little travelog of the adventure.
