Frame Information
Bikepacking Machine
With the go-anywhere spirit of modern-day gravel riding, we set about creating a gravel bike that would be great over all terrain — a true G.O.A.T.
Whether on tarmac or the roughest gravel paths, the G.O.A.T has been designed with confidence-inspiring geometry and the beautifully compliant ride quality that only comes from carefully selected, high-quality butted steel tube sets.
Whether you are exploring remote places in the UK or crossing continents, the G.O.A.T can easily become your ultimate bikepacking partner. Simply add rack mounts and extra bottle bosses for everything you need to carry.
The reasons a Curtis feels different.
Since 1972, we've built steel frames recognised among the finest in England.
Fillet Brazing
Brian Curtis' signature brazing technique creates beautiful rippled joints and airtight tubes, protecting Curtis frames from internal rust.

Latest Review
The G.O.A.T. is a very well thought out frame, not only in terms of tubing selection and things like tyre clearance, but in a way that the geometry creates a platform that is so versatile for all kinds of gravel riding whether that be performance or adventure related. Being handmade in the UK is also a big bonus, especially when it has been as well made as this one. Ignore those thoughts about heavy steel frames, as the GOAT feels lively and nimble while retaining superb ride quality.
