jackal Dirt Jumping

Dirt-jumping, pump-tracking, bike-parking or prowling the streets with your pack, Jackal is an opportunistic scavenger of man-made terrain.

Unique sliding rear dropouts welcome gears or single speeds, whilst the cleverly designed asymmetrical yolk allows for super strong and compact 15.2” chainstays.

Overbuilt to last forever, yet still weighing in under 5lbs, owning a Jackal’s one of the few things in life that requires no justification... every bike shed should harbor one.

*Only available as a frame. Build shown as serving suggestion.

FAQS

Can I mount a chainguide to my bike?

Yes, this bike has been designed with ISCG-05 chainguide mounting tabs. We have had great luck with the E13 LG1 Tr, MRP Lopes guide or Mini G3. For dual ring guides, try the E13 TRS+Dual or MRP 2x guides. These should fit with minimal or no modification.

Is there an option to make this bike a single speed?

Yes- single speed dropouts are available for purchase on our webstore. They accept a standard 135x10 hub.

What is the torque spec for the seat collar?

We don't provide a torque spec for the seatpost, because it really depends on what seatpost you are using. Some seatposts are slippery, and require more torque to stay put, and others are very thin- and can be crushed by overzealous tightening. Some are both slippery and thin...
You will not damage your frame by overtightening the seat collar, assuming you have a 30.9mm seatpost in it.

What kind of headset does this bike use?

We use a headset generally referred to as "mixed tapered". This is a 44mm internal upper cup, with an external 49mm lower cup. The SHIS name is ZS44/28.6 EC49/40.

What kind of rear brake adaptor do I need?

This frame uses a standard IS rear brake mount. Just pick your rotor size and order the correct adaptor to go from IS to post mount (all modern brakes).

What size bottom bracket shell does this bike use?

We use a standard 73mm threaded BB. Nearly any crank on the market (besides BB30 cranks) will fit.

What size rear hub do I need?

This bike uses a standard 135x10mm quick release rear hub.

What size seatpost do I need?

We use a 30.9mm seatpost. Always ensure it is inserted into the frame a minimum of 100mm (4").
