150 mm rear, 160 mm front travel with mixed wheels

Leverage Curves
The GiddyUp suspension system is built to deliver great performance without overthinking setup, so you can just grab your bike and ride. It uses a balanced 27% progressive leverage curve with consistent rate change, paired with tuned anti-squat for efficient pedalling and smooth acceleration. Moderate chain growth, which decreases after sag, helps keep suspension active without interference from chain tension.
On trail, this creates a ride that's supple off the top, supportive through the mid-stroke, and ramps up smoothly at the end, working well with both air and coil shocks. A wide 27 to 33% sag range lets riders fine tune the feel from playful to planted, all without needing to fuss with extra adjustments.
- Clean Cable Routing: Cable routing ports are compatible with 0, 1, or 2 cables and allow brakes to be run on either side.
- Charge Port: Our custom charge port door uses magnets to ensure it stays closed on even the rowdiest of descents.
- Integrated Protection: While a preinstalled Loam Hat keeps dirt and debris away from your main pivot bearings.
- Integrated Chainguide: The sleek and effective top guide keeps the chain in place while being easy to open for maintenance.
