 Product Description

Orro Terra G Hydro 105 Gravel Bike

"Orro has thought carefully about practicalities with the Terra Gravel – it’s a bike that’s designed to be ridden hard and far." - Outdoor Fitness

The 105 Hydro version of the Orro Terra Gravel is the latest evolution of our original gravel bike. With the additional braking power that is provided by hydraulic disc brakes, you can be more confident when stopping even in wet and icy conditions. The extra braking power combined with our Terra G frame makes for an excellent combination. 

Designed with venturesome riders in mind; those who may want to take the shortcut along the towpath; hammer the bridleways instead of the tarmac. Unlike the very first versions of the Terra Gravel, the latest iteration now comes with 35mm tyre clearance (32mm with guards) which allows for ultimate control, comfort and grip and for 2021 in these brand new Vesuvius Silver and Electric Blue colours.

" I loved having a Orro Terra G Bike, From Gravel Riding to Cycle touring, Road riding and Sportives to dropping the kids of at school, it's just been the best bike for practicality i have ever owned" - Richard Salt Dog Cycling Owner
