        Santiago knows its heritage; cold-worked, air hardened steel (100% recycled) is steeped in the history of long distance riding. But with bang up-to-date geometry, Santiago has a refreshing feel that you know will be good for years to come: 450 mm chainstays, 1.1 m wheelbase, 71 degree head angle, a fork rake of 55 and generous tyre clearance. This makes for a truly comfortable, fast, assured bike, both in its own right (audax slaying, winter riding) or when racked up for multi-month adventures.

        Reynolds 631 steel tubing

        Durable, smooth and assured on those multi-month trips Reynolds 631 steel is an excellent material for round-the-world touring where you’re completely dependent on your bike. We’d be surprised if you needed to get your frame repaired, but it’s comforting to know that finding a steel welder in the middle of nowhere is far easier than getting your alloy frame repaired.​

        Traditional bike, contemporary geometry

        Santiago’s takes classic road bike geometry as a starting point, with a longer wheelbase and higher stack height for a more comfortable riding position and assured ride, whether you’re travelling light or fully loaded up.

        Generous tyre clearance

        Clearance for up to 650b x 47 mm or 700c x 37 mm tyres that make your ride more comfortable and give better grip on the bitumen as you corner.

        Full traditional mounts

        With full rack and guard mountains, 3 sets of bottle cage bosses and extra cage mounts on the fork, Santiago can handle being fully loaded up.

        Geometry and Sizing


        Generally we recommend:
        Small: Riders between 5ft 2in and 5ft 7in (157-170cm)
        Medium: Riders between 5ft 6in and 5ft 10in (167-177cm)
        Large: Riders between 5ft 9in and 6ft 2in (175-187cm)
        X-Large: Riders 6ft 2in and over (187cm)

        You can also take into consideration the standover height to ensure you pick a bike that will be a good fit. If you measure your inside leg and ensure there is a minimum of an inch from the toptube to your crotch this will give you enough seatpost adjustment to find your optimum saddle height.
