Orca isn’t just light. It is 6.7kg of climbing technology designed to change how you reach the top.
Achieving Orca´s light weight required many marginal gains, focusing on the details and using the best materials across the range. Considering the bike as a package means working with component and wheel designers right from the start to optimize stiffness and weight.
But having the lightest bike is worth nothing if it isn’t stiff and efficient. When we designed Orca, we started with a target rigidity to ensure that even the strongest climbers could be sure of efficient power transmission. Then we designed Orca to be as light as possible without compromising that number.
Clever frame design means that stiff doesn't have to be uncomfortable. Rounder frame sections help reduce vibrations, saving energy on longer rides and offering you an advantage on that final climb. Wider clearance allows for tires of up to 32mm- maximising traction and compliance.
Occasionally, without notice, manufacturers change product design and/or specifications.
