The Helium frame is our ultra-gourmet bike. It's simply at the highest level when it comes to stiffness to weight ratio. We've designed it to be as light as possible to tackle the longest, steepest climbs. Yet it is stiff and durable enough to expertly handle the likes of andr� Greipel putting all his power on it in a sprint. It's also comfy enough to keep you motivated to ride long distances to tackle Gran Fondos.
