Cube Attain GTC SL is an mid-level performance road bike. Ideal for the rider looking to start road riding and wants a carbon bike at an outstanding price. The relaxed geometry also suits the long distance commuter perfectly.

The Attain GTC SL frame is a monocoque carbon fibre unit, designed to offer a blend of performance and comfort. The big volume down tube, combined with the PressFit bottom bracket and tapered head tube, ensures that the rider's efforts are efficiently converted into forward propulsion, and the rear end's slim aero Flex Stays are designed to reduce the impact of road shocks on the rider - a clear advantage on longer rides. The frame features Cube’s Road Comfort Geometry, designed for long days in the saddle and Gran Fondo style events. The more relaxed geometry also makes this bike suitable for people who have a longer commute or are riding socially.

The Attain GTC SL features a full Shimano Ultegra groupset for absolute performance and incredibly smooth shifting. A compact crankset paired with a wide range cassette gives this bike excellent hill climbing ability and allows the rider to maintain an efficient cadence even on the longest accent.

The Cube Attain GTC SL is a mid-level carbon road bike designed with comfort in mind. This bike is ideal for the new rider, or someone looking for comfortable ride in a lightweight package.
