Unlock a world of adventure and redefine your mountain biking experience with the Transition Spur. This remarkable bike is designed to effortlessly connect you to the trail, making it feel like a natural extension of your body. With its lightning-fast and efficient performance, it provides an almost weightless sensation and precision control, urging you to conquer steeper climbs, venture farther, and conquer any descent you encounter along the way. Prepare to be amazed as you enjoy the newfound speed that comes effortlessly, even in places where you're used to constant pedalling. But don't be fooled by its lightweight and uphill-oriented features; the Spur requires no adjustments to handle descents like a pro, and you might find yourself descending even faster.

Transition's "GiddyUp" suspension system is engineered to intuitively adapt to a wide range of setups. Sometimes you just want to grab your bike and go without worrying about fine-tuning your settings. With GiddyUp, you can hit the trails with confidence, knowing your ride will always feel exceptional.

The Spur boasts nearly 30% progression and maintains a consistent linear rate of change, striking a perfect balance between support and sensitivity to small bumps. The anti-squat feature is finely tuned to enhance pedalling efficiency and acceleration without interfering with the suspension when it's needed most.

The GiddyUp suspension system and a one-piece flex stay rear triangle, is optimized to work seamlessly with inline-style rear shocks. It offers a well-balanced ride when paired with 120 mm travel forks. Riders have the flexibility to add or remove volume spacers in the rear shock to match their unique riding style, and there's ample control for those rowdy moments. The Spur comes with 120 mm of rear wheel travel when equipped with the supplied 190 mm x 45 mm stroke shock. If you prefer a shorter travel experience, you can opt for a 190 mm x 40 mm stroke shock to reduce rear wheel travel to 100 mm.

With a versatile sag range of 25% to 35%, you can fine-tune your bike's feel to suit your preferences – from a firm and responsive ride to a more supple and active one. Best of all, there are no remotes, levers, or knobs to fiddle with; simply grab your bike and GiddyUp, and hit the trail with confidence.
