Geometry and Sizing
Jackal is an opportunistic scavenger of man-made terrain.
The Jackal is a no BS dirt jump, pump track, and urban assault bike. We sell it frame-only and it’s #26forlife.
Overbuilt to last forever, these frames will take more abuse than you can dish out, yet still weigh in at under 5lbs.
The clever asymmetrical yoke permits rock solid and super short 15.2-inch chainstays. And for those who want to take their anarchy further afield, the unique sliding rear dropouts allow for a geared as well as single speed set-up.

If you're on the cusp between the recommended height range of two sizes, the absolute best thing is to try to ride them both. At a minimum, check the stack/reach measurements on your current bike and compare it to the new model you are looking at to get an idea of a fit you are already comfortable with. If riding the bike is not an option, consider the following.
A larger size frame will be more stable, and will give you more room to move without upsetting the weight-balance of the bike. The larger size will put the front wheel further in front of you, which gives the feeling of security and conversely, it will require more significant body movements when you WANT to shift the weight-bias of the bike. Think hard about your riding style and how active/intuitive you want it to be vs stable and speedy. You'll need to work a bit harder to muscle the larger bike around.
Not all bodies at a given height are the same. If you have longer legs and a shorter torso than the average person your height, that may push you towards the smaller of the recommended sizes. If you're all torso and arms, most likely you'll want to size up.
