Sector Dhi Carbon Front MTB Rim - Black - 32H, Black

Product Description

Sector Dhi Carbon Front MTB Rim Ready for racing, this MTB rim features a robust unidirectional carbon fibre rim construction, which means that you can benefit from its exceptional strength without adding any unnecessary weight to your ride. Sector has taken this model's design a step further by also integrating Te Xtreme Innegra into the layup of the rim. This gives it 75% more impact resistance than a standard carbon rim of the same profile. Coming equipped with tubeless tyre compatibility, this DH race-ready rim means that you can enjoy greater stability & a lower weight on the most technical of trails. 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 & energy dissipation. The Tex Treme fabric used in the layup of the rim is a Spread Tow fabric built from a hybrid of Innegra & 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) & it facilitates the use of less resin (lower weight). In the 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 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 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 & to improve traction. Such an improvement in vertical compliance also brings a radically enhanced ride quality. The Innegra equipped rims do not have the associated harsh stiffness of regular carbon wheels. Significantly more impact resistance... In the lab the rim was able to handle impacts of almost double the standard required for MTB wheels by the UCI. The 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 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 & compliance advantages, the use of Innegra also allows the construction of an extremely lightweight rim.
