With its ultra versatile geometry and 1000g frame weight, the Hakka MX is just as happy crushing the local club ride as it is jumping barriers or camping out. The Hakka MX offers internal routing for 1x drivetrains and a dropper post, plus compatibility with Di2 or AXS 2x gearing and a sleek downtube-mounted Di2 battery. 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. The Hakka MX has flat-mount disc mounts and fits a 160mm rotor. The fork has fender eyelets, internal cable routing, and monster clearance for 700c x 45c tires. There's also a removable rear fender mount on the seat stays. The Hakka comes in five frame sizes: 49, 53, 55, 58, 61
