One of the most important aspects in the designing of any bike is the materials used. We have used a bespoke carbon fibre layup which incorporates both high modulus and low modulus carbon into the weave, this has given us the perfect blend for our gravel bike. This is complimented by Innegra impact protection, which helps protect against catastrophic failure in the event of a rock strike.
Sigmatex is one of the world's leading independent converters of carbon fibre. With the largest range of textile technologies and proprietary manufacturing equipment, Sigmatex supplies a wide spectrum of advanced composite materials to the automotive, aerospace, marine,wind energy, sports and leisure markets from its global locations. Sigmatex has a proven track record, converting large quantities of carbon fibre each year for major projects that require high levels of quality and reliability.
Innegra is a high modulus polypropylene fibre that can be used independently or in conjunction with other fibres to provide weight reduction, excellent levels of impact resistance and damage tolerance. We have strategically layered Innegra into the Terra C frame to improve its impact resistance during off-road excursions.
At ORRO we design bike that we want to ride, that's why each one of our bikes is shaped by the countryside around us. The Terra C has been specifically designed to be able to handle the varied terrain that is prevalent in the UK. Rough roads, sandy trails, mud, grass and gravel tracks are where the Terra C comes into its own.
One of the most vital features of any good gravel bike is tyre clearance, so we have designed the Terra C to accommodate up to 44mm tyres. This increases comfort significantly and allows plenty of room for debris to pass through the fork and stays without damaging the frame of hindering the rider. The Terra C has a rack limit of 5kg, when using racks and mudguards please esure that they are only mounted with the bolts provided.
The Terra C has been designed with versatility in mind. That's why we have added front and rear mudguard mounts, making it perfect for commuting all year round. Want to try your hand at bikepacking? The Terra C also has mounts for a rear pannier rack, letting you explore on your bike while being fully self-sufficient.
