Hakka MX Specific FAQs
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):
And any 24mm SRAM-compatible BB (see our BB list on the website)
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.
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.
The Fox 32 Taper Cast fork will clear all sizes of Hakka MX. The fork is 40mm taller than the stock Enve fork, so the Hakka's geometry will be slackened, significantly altering the geometry. Unlike the previous Fox 32 AX, there will not be interference between the frame and fork using the Fox 32 Taper Cast.
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 to change any of these when ordering your bike.
45.0-45.5mm with a majority of cranksets. 47.5mm with Sram Wide cranksets.
Yes, Sram Wide cranksets are compatible with the Hakka MX. These cranks will change the bike's effective chain line to 47.5mm vs. the standard 45.0-45.5mm.
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.
