The HELIX R 12 Speed Cassette is an upgrade to any SRAM Eagle™ drivetrain, with more range than any other cassette on the market. The 9 tooth cog lets you step down one chainring size while keeping the same top end gearing and provides not only better ground clearance, but an overall lighter drivetrain. The aluminium one-piece 42/50 tooth cluster is easily replaceable so riders can keep their steel cluster for multiple seasons and freshen up granny as needed without buying a whole new cassette.It’s in our DNA to solve problems. Helix components are engineered to bridge the compatibility gap between SRAM™ and Shimano™ components, ensuring versatility and flawless performance. Future-proof your bike with e*thirteen Helix.Works flawlessly with Shimano™ and SRAM™ 12s drivetrains despite the challenges in designing for the different cog spacing and chain behavior. Additionally, if your wheel has a SRAM™ XD™ Driver and you want to upgrade to Shimano™ 12s, you not only save money on the cassette, you don’t have to spend the extra on a new hub driver either.Unlike SRAM Eagle™, Helix R cassettes have replaceable gear clusters. That means ongoing service and replacement costs will be less than half that of SRAM™ cassettes. Key Features: 556% More range than any other cassette on the market, 9,11,13,15,17,20,23,27,31,36,42,50,Weight: 345g,Compatible with SRAM and Shimano 12speed drivetrains,Improved shifting performance including Shimano™ 12 speed compatibility,Improved interface between steel and aluminium clusters,.
The BORG 26 All Weather wheelset provides guaranteed reliability in all conditions. The wheels are built with high mileage riders in mind and therefore are suitable for all types of riders. Those that ride in the foulest of conditions and simply need dependable wheels will love these wheels from BORG. Dependable does not have to heavy though. The BORG 26 have every detail covered.

They are mainly used as an all-weather training wheelset. The rims are not expensive if they need to be replaced which is unlikely and the hubs, well they love the wet. Bearing life is long in all conditions. The rim is 24mm wide and 26mm deep. It weighs 475g. The rear rim has offset drilling for increased NDS spoke tension (this is a good thing for spoke life). The internal width of this rim is 19mm and it has a 2mm thick spoke nipple bed. All tyres will sit wider on this rim than they would on a narrower one. This improves rider comfort due to the increased air volume and due to the different tyre shape handling in the bends particularly over broken road surfaces is improved. These wheels are robust, and the rims are low cost meaning they are perfect training wheels and ideal for wet weather/winter use. They are supplied tubeless ready with tubeless tape and valves. Tubed tyres can of course be fitted and are an easy fit. Even Schwalbe Marathons fit with ease. Please note that the images are for illustration purposes only.

The Revo line allows you to get your first taste of the BMX world on a solid and well-designed bike. We took extra care when hand selecting the components on these bikes to ensure that the bike could be ridden straight out of the box, simple to work on and maintain, but also easily upgradable over time. Despite the low price-point, the Revo is packed full of great features like 25-9 gearing and short/responsive pro-inspired geometry.The Revo 16? is a scaled-down version of the 20?. We designed the Revo to follow a similar responsive geometry set as our Dice 16?, allowing the younger rider to really put this bike through its paces. Despite the low price point, you’ll find plenty of neat details on the Revo 16? including the tapered fork blades and even an alloy seat post to help shred the grams.

Sector 9i Carbon Front Mountain Bike RimReady for shredding the trails with your friends as well as exploring new off-road routes on your own, this carbon MTB rim is engineered for maximum performance. It features a hard-wearing unidirectional carbon fibre rim construction, which allows you to benefit from its fantastic strength without adding any unnecessary weight to your ride. Sector has taken this model's design a step further by also integrating TeXtreme Innegra into the layup of the rims. This gives it 75% more impact resistance than standard carbon rims of the same profile. The 9i MTB rim is significantly more resistant to wear and tear and less prone to catastrophic failure.So what is Innegra?Innegra is a fibre derived from polypropylene that exhibits some highly beneficial properties, including high strength-to-weight ratio, resistance to damage, vibration damping and energy dissipation. The TexTreme fabric used in the layup of 9i rim is a Spread Tow fabric built from a hybrid of Innegra and T700 carbon fibres.The Spread Tow layout is significant because it also contributes some positive attributes - the fibres are straighter (reduced crimp therefore higher strength) and it facilitates the use of less resin (lower weight). In the 9i rim the Spread Tow fabric is used on the outer layer of the rim, giving it the unique checkerboard pattern.Sounds good, but what does that mean for a rim? Significantly more compliance... Under a lab test the 9i rim was 50% more vertically compliant than a unidirectional T700 carbon rim of the same profile. This test involves loading the rim with a 100kg weight, in which the 9i rim exhibited a deflection of 15.74mm compared to 10.55mm on the standard T700 rim. It is widely acknowledged that vertical compliance is important for damage reduction (less likely to crack), a reduction of fatigue and to improve traction. Such an improvement in vertical compliance also brings a radically improved ride quality to the 9i wheelset.The Innegra equipped rims do not have the associated harsh stiffness of regular carbon wheels. Significantly more impact resistance... In the lab the 9i rim was able to handle impacts of almost double the standard required for MTB wheels by the UCI. The 9i rim withstood an impact of 140J compared the UCI stipulated requirement of an 80J impact, making it 75% stronger than the UCI requirements.In real world terms, the 9i rim can handle the equivalent of dropping a 15kg weight from a height of up to 1.08 metres onto the bare rim, thus making it 18% stronger than a recognised leading competitor who has published their data. Much less weight... Despite offering strength and compliance advantages, the use of Innegra also allows the construction of an extremely lightweight rim. The Innegra equipped 9i rim weighs just 428g (29”).Features: Rim Material: T-700 Unidirectional Carbon Fibre; Outer layer: TeXtreme Plain Weave Spread Tow Carbon Fibre and Innegra S Hybrid Use: MTB Rim Size: 29" Holes: 28h or 32h options Rim Width: (Internal) 29mm; (External) 35mm Rim Depth: 25mm ERD: 591mm Tubeless: Yes Single or Pair: Single Weight: 428gBuy Sector Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
