At a Glance
Reynolds 631 steel touring frame for loading up and riding around the world.
- Frame: Sonder Santiago frame, Reynolds 631 steel
- Fork: Sonder Santiago, Cromoly steel
- Tyre clearance: up to 650b x 47 mm or 700c x 37 mm
- Full rack and guard mounts, 3 sets of bottle cage bosses
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.
