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.

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.

The Fox 32 Taper Cast fork will clear all sizes of Hakka MX. The fork is 40mm taller than the stock Enve fork, 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. Please note: The Hakka MX only supports the Fox 32 Taper Cast with 700C wheels, not 650B.

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

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.

Many of our paints are available online via My Perfect Color. Some automotive retailers have the ability to custom match paint.

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.
