HE 1800 SPLINE® Designed to enhance the pleasure of riding. When you don't have the wind at your back, an electric-assist road bike can give you the support you need to enjoy the delights of long rides. The HE 1800 SPLINE is designed specifically to meet the demands of e-bikes. With a wider internal width, the hooked rim accepts wider tyres for an ideal combination of comfort, grip and durability. The reinforced spokes and hubs ensure excellent longevity, while the Ratchet LN freehub system delivers reliable power transfer thanks to its simultaneous engagement. The result: a tough, durable wheel that lets riders focus on just one thing: enjoying their ride.
