Compatibility

Specialized S-Works Demo 11 Frameset is a Specialized mtb frame. Everything listed below was matched on a specification we hold for both parts: the interface each pairing actually depends on, such as freehub body, speed count, actuation or mounting standard. Where we could not verify that interface, the part is left out rather than assumed to fit.

Frequently Asked Questions

What fits Specialized S-Works Demo 11 Frameset?

On this page we list bottom brackets for this frame shell, brake calipers this frame mounts, headsets for this head tube, seatposts for this seat tube, forks with a matching steerer and wheel size. Each listing was matched on a specification we hold for both parts; anything we could not verify is omitted rather than assumed to fit.

Can I mix Specialized S-Works Demo 11 Frameset with road components?

Specialized S-Works Demo 11 Frameset is recorded as a mtb component. Some standards do carry across (cassette spacing at a given speed count, for instance), but cable pull ratio and chainline frequently differ between mtb and road groups, so check the specific pairing rather than assuming it carries over.
