Hakka MX

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

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 70040c or 27.52.1” tires.

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 disc mounts and fits a 160mm rotor. The ENVE G Series Grav­el fork has fend­er eye­lets, inter­nal cable rout­ing and mon­ster clear­ance for 700c x 50c or 27.5″ x 2.25″ tires. There’s also a remov­able rear fend­er mount on the seat stays.

Hakka MX Specific FAQs

All our manuals are available here.

The Hakka can accommodate up to a 700c x 40c or a 27.5” x 2.1”.

The max single chainring for the Hakka MX is a 48t. The minimum is a 34t. The Hakka is also compatible with the following double chainring combinations: 53/39, 50/34, 46/36, 52/36. The 34t inner ring on a 50/34 is the smallest we recommend. Any smaller may cause chain contact on the underside of the chainstay.

  • The bike came with a noodle (in the bag of stuff), you’ll need that.
  • Feed a shift wire (an old one) through the noodle so the the cable nub is stuck in the open end (where housing would fit in)
  • Feed the bare end of the cable through the cable stop from the inside so that it exits out the frame along the seat tube. This is the trickiest part, it helps to put a little kink in the end of the cable
  • Pull the cable all the way out the port so that it is pulling the cable noodle into the cable stop. Use a fourth hand tool to pull on the cable and massage the noodle so that it is firmly placed in the cable stop (should be a snug fit). Once it is in place in the cable stop, leave it there!
  • Once the noodle is in the cable stop, remove the cable and route your cable housing from the front shifter to the noodle (internal to the down tube). The end of the noodle should be accessible from the bolt-on door underneath the down tube.
  • Feed your shift cable from the shifter, through your housing, into the noodle, and out to the front derailleur. If the cable catches on the cable stop upon exiting the noodle, it may help to add a kink to the end of the cable.

There are a number of power meters that fit on the Hakka from Quarq, Stages and SRM (note that we have not found any left crank arm power meters that clear the chainstay, but there are numerous right side options).

For SRAM (Quarq) power meters, they have 24mm spindle options and DUB spindle options.
The best setup is this power meter:

With either of these cranksets:
(DUB Spindle) https://www.quarq.com/product/quarq-dzero-dub-crank-arm-assembly/
(24mm spindle) https://www.quarq.com/product/sram-red-crankarm-assembly/

And these chainrings (1x and 2x options available):
1x: https://www.quarq.com/product/x-sync-road-chainrings/
2x: https://www.quarq.com/product/sram-force-chainrings/

And any 24mm SRAM-compatible BB (see our BB list on the website)

For Stages:
Both the Ultegra and Dura Ace 2X right-side cranksets should work fine

Want to run a 1X with the Stages meter? Wolf Tooth has a solution:

But it requires a little filing to fit these above cranks:

You can use any Shimano 24mm-compatible BB listed on our website. The Praxis BB is highly recommended.

For SRM:
Any of SRMs crank-based power meters will fit. To assure bottom bracket compatibility, we recommend meters based on the SRAM cranksets:

Here's what each wire length is intended to connect:

1200mm: Connects A junction box (at stem) to B junction box (inside down tube)

900mm: Connects B junction box to rear derailleur (routes through right chainstay)

2x400mm: connects right and left shifters to A junction box. The left shifter is not necessary, but we include it anyway in case someone wants right-up/left-down type shifting

350mm: Connects battery (zip-tied to down tube battery door) to B junction box.

Try to attach the B junction box to the battery so that it isn't rattling loose inside the down tube. Another option would be to wrap it in foam so that it doesn't make any sound as it bounces around.

We do not recommend installing a Fox AX fork on the Hakka, as it significantly alters the geometry.

The Fox AX fork will only fit on the 55cm frame! It will touch the down tube on all other frame sizes. And it messes with the geo a lot, slackening the angles. It is not recommended.

You can find torque specs for the Hakka MX in the tab on the right.

170mm crank on 49cm

172.5mm crank on 53cm, 55cm and 58cm

175mm crank on 61cm

80mm or 90mm stem on the 49cm

100mm stem on the 53cm and 55cm

110mm stem on the 58cm and 61cm

Note: you may request changing any of these when ordering your bike.

To plug the holes where the fender eyelets are, use M4x0.7 bolts. Same size goes for the hand job mount on the seat stay if you want to remove that. We use 10mm long button head screws to fill the holes when there's no part mounted.

Hardware Torque Spec (Nm) Thread Treatment / Notes
Cable Port 2 Grease
Rear Brake Caliper 6 Loctite 243
Seat Binder 5 Ti anti-seize
Derailleur Hanger Bolt 5 Grease
Bushings Apply Slick Honey (grease) to all bushings during reassembly.
Hexle Rear Axle There is not a numerical torque figure for the Hexle. We recommend tightening the 5mm with your multi tool that you carry with you. This way you’ll be able to remove it in case of a flat out on a ride.
