Surprisingly comfortable and high performance long-distance race bike!

The CUBE Attain GTC Pro has carved out a bit of a name for itself - as a great value speed machine that's not just quick and efficient, but light and comfortable too. Jump aboard this bike and you'll quickly realize why carbon has established itself as the discerning rider's frame material of choice. Details like the shock-absorbing Flex Stays and stiff, strong down tube create a combination of inspiring speed and beguiling comfort. Combined with equipment highlights like the Mavic Aksium RS wheelset and slick-shifting Shimano 105 transmission, this is the ideal race bike for demanding riders looking for a companion on long, fast rides. Oh, the letters "GTC" ? They stand for Gran Turismo Composite. CUBE thought it was a fitting name. 

The CUBE Carbon Comfort Frame was developed from the ground up by CUBE engineers to combine class-leading comfort, performance and low weight. The beauty of carbon construction is that, with the right expertise, practically anything is possible. So, for example, 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 riders, increasing comfort and reducing the symptoms of fatigue and tension. 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 that every steering impulse is precisely transmitted to the front wheel. As you'd expect, CUBE maintained the frame's elegant looks by routing cables internally, which also has the benefit of keeping gear shifts cleaner for longer. 

• Gran Turismo Composite - In designing the GTC carbon fiber frames, safety and comfort are the main factors. CUBE use high modulus fibers for the parts which are stressed the most ?the head tube, the seat tube top and the bottom bracket area. That is why the frame still offers flex and comfort resulting from the flexible tubes. CUBE's special production process with inner and outer molding forms ensure that the minimum of required material is used, reducing overall weight even with complex frame designs. All GTC frames have of course passed DIN - Plus testing.
• Twin Mold Technology - The Twin Mold technique uses re-usable cores during the lay-up process to ensure precision frame moulding. Special inserts guarantee optimum ply orientation during the production process to add extra strength at frame points subject to higher loads. This improves the safety of the product and delivers outstanding stiffness characteristics.
• Integrated Cable Routing - Internally routed cables offer many advantages. Cables are protected from dirt for longer life, weight is saved thanks to the absence of external housing and the bike has a clean, sleek appearance.
• Tapered Steerer - This steerer tube design is stiffer than a conventional straight steerer and yields a more secure ride feel even in difficult terrain. Minimal flex at the front of the frame means the greatest possible steering precision. With the larger steerer, the forks become more rigid. At the same time weight is saved due to the absence of bearing shells as the lower bearing is fully integrated into the headtube. On all of CUBE's carbon models the upper bearing shells are also directly in the frame, so that once more a few grams are saved and the energy transfer is very direct.
• Press Fit BB - With Press Fit bearings, the bottom bracket bearings are pressed directly into the frame and not screwed in as usual. This gives a wider bottom bracket shell and allows them to build a wider downtube and more broadly-spaced chainstays. Every millimeter of additional width gives a significant improvement in lateral stiffness.
• Wet Paint Surface - On polished, brushed aluminium and all HPC frames, the logos and graphics are applied in multi-layer wet paint. CUBE use this surface treatment technology mainly to save weight.
