The SL was born out of the quest to create one of the lightest bikes in the world by building off our grand tour-winning design and introducing technology that shattered expectations of what’s possible.
At a staggering frame weight of just 695 grams, the SL is 19% lighter than any bike we’ve ever produced and is flat-out one of the lightest bikes in the world.
Not only is the SL significantly lighter, it’s significantly stiffer: 9% stiffer in the head tube, 11% stiffer in the bottom bracket, and 18% stiffer in the fork (than our Altamira) for maximum efficiency and superior handling.
Intelligently designed to ensure optimal ride quality for every cyclist, the SL features two fork offsets, unique tube diameters and layups per frame size, super-thin seatstays, a chain watcher, and a chainstay protector.
When climbing the world’s steepest gradients, the lighter the bike, the faster the rider conquers his mountain. And when meticulously evaluating where one tenth of a gram can be shaved, smart things happen.
The latest evolution of our road lineup uses some of our most successful technologies – High Compaction and RIB Technology – in new, unique ways, while utilizing brand-new innovations such as an octagonal downtube constructed of ultra high-strength carbon, injection-molded cable stops, and a frame with only four bonded joints.
The SL was cleverly and skillfully engineered to ensure the lightest, stiffest frame possible – a machine WORTH THE WEIGHT.
