Curtis S1 SuperMoto

If singlespeed is your thing, this frame is for you

The Curtis S1 SuperMoto is a single-speed version of the XC100 which we have been making for years. It’s built for a 100mm fork but as with all our frames you can have it built to match whatever fork you wish to run. The S1 & S1 SuperMoto are the same frame which can be set up for Dirt or Road, also available is our 29″ version the S1-9.

Available made to order in sizes small (16″), small/medium (17.5″), medium/large (19″) and large (20″), or custom.
