The bike is an adventure focussed bike that shares all the same DNA as the Fiadh model but with increased tyre clearance.


This bike is named after Tom’s late mother Cilla Sturdy. Cilla was an enthusiastic cyclist with a real sense of adventure. Cilla’s tendency to reject the classic ‘out and back’ style route would often find her rambling through farmers fields and skipping gates in search of a more intrepid route. This bike is a tribute to her curiosity for the great British countryside and love of the natural world.

With a fully customisable geometry set this bike is the Sturdy answer to a modern multi surface drop bar bicycle. Whether you think of it as adventure, cyclocross, fast touring, all-road or gravel style riding this bike has got you covered. We developed and tested this bike on the numerous gravel and single track routes in our home counties of Somerset and Wiltshire. We’re happy to say that our customers have also been enjoying these bikes far beyond our county borders. 

Cilla is perfectly adapted for a variety of off-road adventures; featuring clearance for tyre widths up to 50mm, comfortable geometry and the option to customise bottle cage and cargo mounting locations. This bike has everything you need to ride with the spirit of Cilla.
