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.
