Titanium gravel frame, made to order in Somerset.

Shaped by years of designing, building, and riding our bikes across the wet byways, bridleways, and holloways of Somerset and Wiltshire, the Drove is our answer to off-road endurance. Its geometry reflects modern gravel bike design at its best: longer chainstays deliver high-speed stability and sure-footed traction on steep, loose climbs, while balanced front-end geometry ensures confident, straight-line tracking over punishing terrain. Sharing the Fosse’s six sizes and three stack heights per size, it easily accommodates a more upright, long-distance position—and finding your ideal fit is simple with our comprehensive fitting tools.

The Drove showcases the latest engineering and manufacturing developments from Sturdy Cycles. We have replaced our 3D-printed junctions and components with fully redesigned, CNC-machined titanium alternatives—machined in-house and built to order at our Frome workshop. This new manufacturing approach introduces a sharp, modern, and minimal aesthetic, ensuring every Sturdy remains a unique proposition: truly functional UK engineering refined with handmade finesse.

Off-road, grit and water find their way into everything, so we've placed phosphor-bronze threads at the thru-axles and seatpost clamp, and each frame kit includes an Enduro headset backed by a lifetime bearing warranty. Paired with the included ENVE IN-Route Gravel carbon fork, the frame kit accommodates tyres up to 700×50mm—with an optional titanium fork launching in 2027 to expand clearance even further to 55mm. Every frame kit also comes complete with an in-house CNC-machined titanium stem and seatpost. Customize your build with optional custom finishing, complete build kits, and titanium crankset or accessory bundles.

Drove or Drovers roads: Ancient rural routes once used for agriculture - many are of unknown age and some are known to date back to medieval times. These rough pathways criss-cross the Somerset and Wiltshire landscape.

Optional extras

Drove build kit, £4,137.60 inc VAT

Everything else you need for a complete gravel bike, chosen by us to suit the Drove and shipped with the frame. We check every part works together before it goes in the box. After you order, you tell us your crank length, stem length, bar width and saddle height, and we put the kit together around you.

Titanium upgrade, +£674 inc VAT

Adds our titanium brake levers, jockey wheels and bar end plugs to the build kit, matched to the groupset. A small touch that makes a build feel finished.

Finishing

Every Drove comes with a choice of standard finishes, included in the price. If you'd like something more personal, choose a custom theme (£600 ex VAT) or a bespoke finish (from £2,000 ex VAT), and we'll work out the details with you after ordering.

Made in Somerset

Every Fosse and Drove is designed, engineered, machined, fabricated and finished in our workshop in Frome, Somerset. We've built hundreds of made-to-order bikes here, and keeping every stage under one roof means we know each frame from the first drawing to the day it leaves. Once you've ordered, Tom and Jack start work on yours.

Both frames are designed to exceed ISO 4210, the safety standard for bicycles, so you can ride them hard, and keep riding them for years.

Questions

What happens after I order?

We'll be in touch by email within a working day to collect your fit details (crank length, stem length, bar width, saddle height) and talk through finishing. Nothing goes into production until we've agreed it all with you.

Which size should I choose?

All six sizes come in three stack heights, and no size is a compromise. The size selector and geometry comparison will point you to the right one, or you can size against your current bike. If you're unsure, email us.

How is finishing paid for?

The standard finish is included. If you choose a custom theme or bespoke finish, we agree it with you after ordering and send the balance as a separate invoice.

Do I need the build kit?

No. The frame kit is complete on its own, so if you already have parts you love or a builder you trust, you're all set. The build kit is there if you'd rather have everything from us, assembled and checked before it ships.

What's the difference between Fosse and Drove?

Fosse is our road frame, with room for 700×35mm tyres, made for long, quick days on tarmac. Drove is our gravel frame, with room for 700×50mm tyres for tracks, byways and rough lanes. Both share the same sizes, stacks and attention to detail.

How long will it take?

About six weeks from order. The first frames dispatch at the end of 2026.
