The Sidi Sixty is a very special cycling shoe to mark the Italian brand’s 60th anniversary. Handmade in Italy, the Sixty is a fresh take on Sidi’s timeless style. With a lightweight chassis, and cutting-edge materials, the high-performance shoe has already made appearances in the pro peloton. The Vent Carbon Sole has been meticulously designed for excellent power transfer, with flex introduced in the front end of the sole for long-ride comfort. An integrated vent can be opened and closed (with a cross head screwdriver), making the Sixty just at home in UK conditions as it is in the heat of Italy and ensuring four season comfort. The Tecno-4 closure system is remarkably advanced compared to the first rotor closure system Sidi designed back in 1988 and is the latest in Sidi’s all-Italian tech closure system. The mechanism consists of a single rotor to reduce the shoe’s weight, and ensures precise, micrometric closure. The release of the tension has been improved for faster closure and release. Like all Sidi shoes, this new Tecno-4 is replaceable if it is ever damaged while the same is true of the rubber heel pad. As well as rotor system, the Sixty also has a high-security Velcro strap across the front of the shoe featuring integrated teeth that lock together when the strap is closed, creating a more secure fit and taking the load. The Sixty’s upper is made from TechPro Microfibre. This innovative and eco-friendly leatherette offers durability, stability, and water-repellency. An anti-mould treatment helps fight the build-up of bacteria, whilst the upper’s Nylon mesh allows great breathability and creates an ideal microclimate inside the shoe for all day comfort. There are also Velcro tabs on the inside to keep the tongue perfectly in place. The heel is a fully integrated design, which has been reinforced to avoid deformations under prolonged use and provide extra support. Anatomically shaped, the heel stabilises the foot and helps prevent heel slip – essential for those tougher climbs, sprints and efforts. A Reflex insert provides greater safety by helping signal your presence to other road users in poor visibility. The Sixty embodies Sidi’s illustrious history and pedigree, whilst being ideal for the demands of modern-day riding and racing. These shoes represent Sidi’s ceaseless drive to provide and create the ultimate in road shoe design, providing you with beautiful style as well as performance.

Campagnolo Chorus Ultra Torque 11sp Double ChainsetThe completely redesigned chainset represents increased rigidity as well as fresh and cutting edge aesthetics.The new version uses a 4 arm spider design which makes for one single crankarm for all chainring options thanks to its unified bolt pattern. Gone are the days of having a dedicated bolt pattern for standard chainrings and another for compact rings. No longer will changing from traditional to compact, or vice versa, translate into the obligatory purchase of a completely new chainset. The new bolt pattern allows for all 3 chainring standards 53/39, 52/36 and 50/34 to be built upon the same chainset. Changing between compact and standard is now as easy as changing 8 bolts and two chainrings. While the new 4-arm bolt pattern makes for a much more practical design that offers the cyclist a more versatile component, the Campy Tech Lab was dedicated primarily on increasing performance characteristics.The new design incorporates a 8 bolt pattern with a spider arm design that not only holds the chainring in place by way of the bolt but also supports the chainring and in doing so, increases system rigidity. In addition to completely redesigning the spider, Campagnolo engineers dedicated a great deal of energy towards a completely new crankarm that is a great deal stiffer than previous versions. Add this new highly rigid crankarm to the new four-arm spider design and you have a complete chainset that not only excels at transferring power more than any previous version but one that is also more versatile with respect to gearing.Features: BCD: Inner: 112mm; Outer:145mm Weight: 684gBuy Campagnolo Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Upgrade your Rally RK100 to a dual-sensing power meter, and analyse more than just watts to see exactly how your pedalling style generates the force that moves you. When paired with Rally RK100, the upgrade pedal completes the Rally power meter system, providing left/right balance data and cycling dynamics. The power sensor is even transferable to Rally XC pedals so you can have power for your off-road rides. Revolutionary cycling dynamics display where you’re generating power throughout the pedal stroke and show left/right balance. See where you apply force on the pedal to ensure proper cleat position and track seated vs. standing to see how position changes efficiency. Compatible Devices: Rally RK100
