The key with great frame design is to build in comfort wherever possible, while retaining stiffness where necessary for efficient pedalling and safe handling. It's a tricky balance to get right, but our engineering team didn't get its reputation for excellence by taking the easy options. That's why the Attain's 6061 aluminium double-butted frame features slim, cross-ovalized aero seat stays - for fatigue-reducing vibration absorption - and a tapered head tube with mechanically formed down tube - for responsive steering and rapid forward progress. The result is the ideal blend of comfort and safe, predictable control in any situation. We've even borrowed some neat features from our high end race frames, including internal cable routing and a PressFit bottom bracket. And there's plenty of clearance for tyres up to 28c - perfect for more comfort on longer rides, or on rough roads.
