Optimised for performance, the SRAM Force AXS XG-1270 D1 12-Speed Cassette supplies smooth, crisp shifting across its wide 12-speed range. To reduce weight and enhance durability, MINI CLUSTER construction sees the three smallest sprockets CNC machined out of a single billet steel block. Compatible with the SRAM XDR driver body standard, this cassette features X-Range gearing for smooth gear progression, reducing noise and wear for lasting performance. Features X-Range gearing gives you more range and a smoother gear progression, so you’re always in the right gear MINI CLUSTER construction reduces weight and increases durability Designed to work with the XDR driver type
For riders who are drawn to the unknown trails and terrain, this stunning 2x12 model delivers the ultimate gearing ratio for every ride. Its chainrings feature Dynamic Chain Engagement+ technology which holds your chain securely on the rowdiest of runs. Weave from trail to trail with its 36 to 26 teeth allowing for almost unlimited possibilities to dominate whatever the mountain has to throw at you. To top it off, its hollow forged crank arms make it immensely robust for carving your way around without any excess weight holding you back. These are an ideal choice of upgrade for unrivalled off-road performance and control.
The SRAM X01 drivetrain carries on the tradition of SRAM’s championship-winning 1X™ philosophy—all the way down the mountain. The setup is simpler. The drivetrain is lighter. And the shifting is fast and solid. Bottom line: X01 is the right one for any terrain, every time. X-Dome X-DOME technology creates an incredibly lightweight, precise and strong cassette. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life. XD Driver Body XD is a new cassette driver body design that allows the use of a 10 tooth small cog and provides an improved interface with the cassette.
Campagnolo’s considerations behind the available gearing ratios smooth shifting are fundamental to the design of Ekar’s gravel and all-road specific cassettes. 13 sprockets make the logic of a Road 1 x system possible. And it’s the introduction of the 9-tooth cog that makes Ekar work so perfectly for gravel and all-road riding. Not only is a wide range of gear ratios possible, but natural, progressive cadence-matching shifts are maintained, offering a uniquely satisfying ride. The range of gears offered by these cassettes matches or exceed any 2x system with no wastage. Closer low gear spacing for smooth cadence progression is matched with wider high gear spacing for top-end speed on a 1x13 system. Technology: 13 speed: full gear range to match or exceed any 2x system with no wastage 2-piece block: blends the strength of steel and the lightweight of alloy Compact: narrow design with quick changes, lightweight and improved chain security

The new Shimano Tiagra 4700 STI levers have seen the biggest changes out of all items in the Tiagra range.These new levers get the look and feel of the higher end 11-speed levers, while sticking with 10-speed internals. As well as the re-designed hood shape the shifters also feature neat under-tape cable routing instead of exiting from the side of lever like previous models.Like the more expensive groups the Tiagra levers provide a shorter shift stroke that delivers what Shimano calls ''lightest and easiest front shifting Shimano has ever made''. The lever is fully adjustable to accommodate different hand sizes via a 10mm screw-type reach adjustment.Braking isn't ignored of course, and the power and feel of the braking has been improved, especially when riding on the hoods. In conjunction with a new cable set, the whole setup is smooth and reliable.Model Number: ST-4703Optical Gear Display: NoCassette Compatibility: 10 SpeedFront Shifting: Triple

In 2016 we started our aero research project with the Norwegian Technical University in Trondheim. Besides having a couple of brilliant professors and PhD students to come up with ideas and do the basic research, they have a couple of wind tunnels, rapid prototyping capabilities, CFD analysis and a true desire to make fast stuff. The first big success from the research was Team Sky's TT suit that placed four riders in the top eight at the opening Tour de France time trial. Then the UCI made it illegal. So this suit isn't UCI legal (but neither is your bike). It's faster than the pro cyclists' suits and very illegal due to the silicone ribs in the arms. The main body fabric is an impossibly light 50 denier — usually in sports clothing 40 denier is considered ultrafine. The legs and sleeves are long for aerodynamics, while the light fabrics are great for dealing with heat since they're thin enough to not get weighed down, yet the 8% Lycra® content holds a bit of moisture next to your skin for rapid cooling. The insane stretch allows us to make something that truly fits like a second skin on the bike but that doesn't restrict in any way on the swim or run. The PR Speed Suit KISS Tri pad offers some welcome padding while you're on the bike but is thin enough to not bother you on the run. This suit offers real time savings on the bike leg while providing cooling and comfort on the run, but it was made with the expectation of being worn under a swimskin or wetsuit for the swim. It's optimized for high speeds — top age groupers or pro athletes, or anyone looking to set a new PR.
