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 GCi 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 GCi rim the Spread Tow fabric is used on the outer layer of the rim, giving it the unique checkerboard pattern.
Spread tow fabrics are mechanically better than standard carbon fabrics for rim application
Sounds good, but what does that mean for a rim?
• Significantly more compliance...
Under a lab test the GCi 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 GCi 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 GCi wheelset.
The Innegra equipped rims do not have the associated harsh stiffness of regular carbon wheels.
Fast riding wheels!
• Significantly more impact resistance...
In the lab the GCi rim was able to handle impacts of almost double the standard required for MTB wheels by the UCI.
The GCi 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 GCi 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.
Distinctive Innegra pattern.
• 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 GCi rim weights just 440g, and our complete wheelset weights just 1690g.
A wheelset for climbers to love
What about the rest of the wheel?
Every detail of our wheel builds is carefully considered, from the super smooth Revo Cream bearings to the straight pull triple butted Pillar spokes. And we back it all up with a lifetime manufacturing defect warranty.
