Santiago knows its heritage; cold-worked, air hardened steel 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.

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.
