The Jackal M has a progressive suspension character. This way the suspension is supple and sensitive around sag, yet big hit capable. Plush with little risk of bottoming out. How progressive a bike is depends primarily on the regression of the leverage ratio.
We tested prototypes with various leverage curves and found the sweet spot: a leverage ratio that decreases by 15% throughout the bikes’ travel.
If you want the suspension to be even more progressive there is the option of adding extra volume spacers in the shock. This is something we tweak when we set up the bike for you, based on your weight and where you plan to ride.
Mountain bikes from major brands tend to be advertised with a single anti-squat percentage. What they don’t tell you is they can suffer from vastly different anti-squat values when shifting down the cassette. We have measured deviations up to 75%.
The Jackal M has a anti-squat value of around 115% at sag across all gears thanks to our chainline not being affected by gear shifts.
So, why 115% anti-squat? In short this compensates for 100% of pedal bob induced by the pedal torque and another 15% to account for your body movement on the bike.
Anti-squat values come down throughout the bikes’ travel: from more than 120% down to less than 90%. This way our team crafted a very efficient yet lively suspension platform.
The Jackal M benefits from very little pedal kickback. Especially at high speed, in heavier gears kickback is negligible.
This is a major benefit because it means the suspension remains fully active and sensitive during quick descends, even when pedaling.
We achieved this thanks to a combination of our integrated gearbox and compact kinematics with limited chain growth.
