Shimano Ultegra R8100 has been completely redesigned with all-new ergonomics, even greater brake modulation and wireless electronic shifting precision. It delivers the world’s fastest and most reliable wireless shifting and a wide gear range which means no matter how steep a climb is, it’s never outside your comfort zone. Di2 gives you instant, accurate, lightning-fast shifts every time at the push of a button. Even in the most extreme of conditions, shifting is precise and controlled. You can even change gear under heavy load while climbing or accelerating. With Di2, you are in complete control.

Accelerate and climb faster, holding speeds you could never have imagined with a high-performance wheelset that delivers the perfect balance of weight, aerodynamics, and efficiency. Cosmic SL 45 delivers more speed, comfort, and control for the best on-bike ride experience. We've matched the wheels with a tyre that lives up to its name; the G-One Allround is a tubeless-ready, multi-terrain tyre that offers a fast and composed ride on dirt, gravel and road.

Ultralight LEVEL 3 carbon monocoque handlebars fitted with a comfortable LEVEL handlebar tape offer multiple hand positions for enhanced comfort and efficiency when climbing, on the flats and descending. These are neatly matched with a LEVEL 3 carbon-wrapped alloy handlebar stem with Titanium hardware.

An ultralight LEVEL 3 carbon monocoque seat post fitted with a Brooks Cambium saddle for more comfort and insulation from road bumps. A wide choice of saddles to suit all body shapes and sizes is also available in BikeBuilder.
