The GTC SL Disc - a suprisingly comfortable, high performance long-distance race bike - is the highlight of the Attain model series. It's so efficient it feels right at home leading out the peloton, whether that's on a long climb or a high speed, twisting descent. Cutting edge disc brake technology means the best possible braking performance with big safety reserves, even at high speed and in poor weather conditions.
Disc brake forces need a different approach to frame design and construction. The Comfort Flex carbon frame is equipped with X12 axles at front and rear - they massively increase the frame's stiffness. It's also the reason Cube opted for a tapered head tube with integrated headset to plug the CSL Race carbon fork into. In complete contrast, Cube incorporated their aero Flex Stays into the rear end, in order to make this uncompromising race machine comfortable as well as efficient. To maximise service life and clean up the bike's appearance, all the cables are internally routed. A PressFit bottom bracket ensures long-term smooth running and efficient power transfer, and Cube have even allowed for winter training rides by including room for mudguards.
It would have been a crime not to select Shimano's Ultegra groupset for the Attain GTC SL Disc - and the same goes for the Shimano BR-RS505 hydraulic disc brakes. Power is transferred via a compact chainset with 50 and 34 tooth chainrings, while at the rear an 11 speed cassette runs from 11 to 32 teeth. Plugged into the dropouts at each end are the amazingly fast DT-Swiss Spline R24 wheels, anchored to the road via grippy and fast-rolling Schwalbe One Kevlar tyres.
