Which to choose: speed or storage space? You can have both with a Hook. With an able steel frame and carbon fork, this bike is fast and versatile. Size-matched 650B or 700C wheels across the sizes provide control and comfort, while the Shimano GRX groupset and double crankset give you a close ratio with a broad range of gears. Take your pick from a range of fixing points, including a direct mount for a top tube bag, triple cage mounts, rear rack and fender. Or, leave it stripped back and fly. The Hook might have been designed as a gravel racer, but that doesn’t stop it from also being a perfect tourer, commuter, or even summer-season crossbike.

With the ability to carry serious loads, triple mounts on the forks and three separate bottle cage fixings allow you to carry as much as you need with you. The Hook EXT C comes complete with a carbon frame and V2 carbon fork with triple cage mounts for speedier off-road raids. Sram provides the bike's 10 – 42T XD cassette for a great range of gears, so you can keep the pace high over whichever surface you decide to tear across. Our friends at Hunt handle the hoops, providing the bike with a tubeless-ready Adventure Sport 27.5" wheelset. Finished with head-turning tan-wall WTB Venture tires, onlookers will have to be quick if they want to catch a glimpse as you fly through the undergrowth. It comes in this year's glossy metallic black colorway, too.

The S5 has one job - get to the line before everyone else. Under the likes of Wout van Aert, Marianne Vos, and Christophe LaPorte, the new model has already proven itself as a tool without equality. In the 2022 Tour de France, this bike propelled Wout to the highest ever Points Classification score of the modern era. At 480, Wout was some 194 points ahead of his nearest rival-tangible proof that Cervelo keeps delivering aerodynamic gains to our World Tour athletes. The new S5 has reduced drag by 65 grams and increased the frame's surface area while still reducing overall weight. The deeper frame sections maximize the shapes allowed by the UCI. Meanwhile, the iconic V-stem has been further refined, and a new fork designed to simplify the entire front end. What's more, a ground-breaking new wheel design concept has been co-developed with Reserve to increase stability and reduce drag in turbulent aero conditions. - V Is For Velocity In pursuit of speed, everyone wants to try different positions to find their most aggressive fit. The S5's iconic V-stem not only inspires confident handling at high speeds, but it's now also remarkably simple to dial in your perfect set-up. All the necessary spacers come with the bike, and there’s now only one bolt length, reducing complexity and making the system 53g lighter in the process. - Frame Enhancements The UCI’s new regulations on aerodynamic design allowed us some additional room to deepen our aero profiles and squeeze 65 more grams of drag performance out of what is already the fastest aero bike on the market. You’ll notice a deeper head tube and BB area, and more aggressive shaping on the trailing edges of the tubes. Since the new S5 is only compatible with electronic shifting, we were able to tidy the dropout a bit and update the shaping all over the bike. - Tire Clearance Wider wheels and tires are faster aerodynamically, and more comfortable to boot. S5 comes specced with 28mm tires but has clearance for up to a 34mm (measured) tire. The frame is optimized to complement the wider Reserve 52/63 turbulent aero wheels. In addition to the handling benefits, this saves over 5 watts compared to the previous Reserve wheelset. - Handlebar Refinement We’ve improved the comfort of the handlebar and tweaked the shape to get a perfectly flat bar-to-hood transition. We now use a two-bolt interface that allows for infinite tilt adjustments between 0 and 5 degrees. - Keeping It Simple Bike fitters at every level are moving away from longer-offset seat posts, and the new S5 comes stock with a 15mm offset post on most sizes (vs 25mm offset on outgoing S5). The old seat posts are forward-compatible, and we’ll keep the 400 mm-long, 25mm offset post in stock for those looking for a more extreme fit. - SRAM Integrated Power Red and Force builds include Quarq Zero power meters integrated into the crank. The integration of a power meter results in better stiffness, lighter weight, and improved accuracy over aftermarket solutions—and the DZero delivers power measurement accurate to +/- 1.5%, even in variable temperatures. - Sorry Campy Fans The 2022 S5 Disc frameset is designed to accommodate electronic shifting groupsets that use connectors up to 6mm in diameter, therefore Campagnolo EPS is not compatible with this frameset. Mechanical shifting groupsets are also not compatible with this frameset.

Unleash your sprint with 200 meters to go. Close a gap, chase back, launch a solo attack. This new aero road machine is made for the moments that count. More aero, more adjustable, more ways to win. INTEGRATED AERODYNAMICS - AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimizes aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and Contact SLR Aero cockpit produce the best overall aero performance. EASIER ADJUSTABILITY - Cable routing through the stem and head tube makes it quicker and easier to adjust or change cockpit components and fine-tune performance and riding position. RACE-WINNING EFFICIENCY - Advanced SL-grade composite frameset features Giant's pro-level composite materials and manufacturing processes. The result is 150 grams of weight savings compared to the previous generation and an even greater stiffness-to-weight advantage.
