The Lightweight Adventure and Gravel Wheelset - carbon wheels with an Innegra Armoured Jacket


The Lightweight Adventure and Gravel Wheelset with a Suit of Armour.

Whether you're spending long days in the gravel, loading your bike up on an adventure or racing cross in the mud, the GCi wheel-set has your back. Designed to excel in high impact environments, our Innegra equipped carbon rims can shrug off the hardest of hits.

The GCi gravel bike wheelset is tough enough for rim strikes on challenging terrain yet light enough for 'cross racing all winter long.

Redefining Carbon Wheels.

Ride without fear - thanks to the addition of TeXtreme® Innegra into the layup of our rims, we've developed a rim that has 75% higher impact resistance than standard carbon rims of the same profile*. The GCi carbon wheels are significantly more resistant to wear and tear and less prone to catastrophic failure.

Our Innegra™ equipped GCi rims also have 50% more vertical compliance than standard carbon rim**. As a result they exhibit high energy absorption and superior vibration damping, with none of harsh stiffness associated with carbon. These are lightweight carbon wheels, that have the sought-after ride characteristic of an premium alloy wheelset.

Durable Doesn't Have to Mean Heavy.

A lightweight, reactive and durable wheelset that can handle a beating. Now you can forget about protecting your wheels and concentrate on finding your flow in challenging trail conditions.

*When compared with same rim shape manufactured with 100% T700 Unidirectional carbon fibre. The GCi rim exceeds the UCI load test of 100J – and passes a load test of 120 J three times with no fracture.

**In rim only vertical deflection tests compared to the same rim shape manufactured with 100% T700 Unidirectional carbon fibre, the GCi rim deflected 50% more, without 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 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.
