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.

Apex1
Apex 1 is a single ring 40 chainset with an 11 – 42t cassette in the back, giving you low enough gearing for tackling the climbs unloaded with the simplicity of a 1x chainset. ..Read moreReynolds 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.
