Disc brake forces need a different approach to frame design and construction. That's why our Comfort Flex carbon frame is equipped with 12mm axles front and rear – they massively increase the frame's stiffness. It's also the reason we opted for a tapered head tube with integrated headset, into which we fitted a CUBE CSL Race carbon fork. To soften the impact of harsh road vibrations, we fitted aero Flex Stays at the rear. They make this uncompromising race machine as sublimely comfortable as it is ruthlessly efficient. Routing all cables internally fulfils two functions. First, it maximises service life, so that your gear shifts stay smooth and precise for longer. And second, it complements the frame's clean, sleek, Gran Turismo-inspired looks. We even allowed for winter training rides by leaving space for full length mudguards, so now you can train and ride in greater comfort.
