UK brand Orro has today launched its new carbon Terra C gravel bike model. The carbon fibre layup incorporates vibration-busting Sigmatex Innegra. This UK-made fibre also improves impact resistance and reduces the possibility of frame damage.
Innegra is incorporated into the frame under the bottom bracket and on the insides of the chainstays and fork blades: areas that are typically prone to rock bashes when riding a gravel bike off road.
Orro says that it has also developed a new geometry for the Terra C that works well in typical UK conditions. So there’s a 72mm bottom bracket drop to lower the centre of gravity and a 71 degree head tube angle for stable handling, coupled with a 50mm fork rake for responsive steering. Orro says that it hasn’t sacrificed on-road speed either.
It's usual for bike models to have a constant chainstay length across the size range. But Orro says that the Terra C’s chainstays increase in length in larger sizes to ensure consistent rider weight distribution and minimise heel rub.
Clearance is important off road and Orro says that the Terra C will take tyres up to 42c width. You can also fit mudguards and a rear rack for wet weather and load lugging duties.
You can purchase the frameset only for £1399.99. It’s compatible with electronic and mechanical groupsets and the front mech hanger can be removed for a clean look to single ring builds.
