Can I mount a chainguide to The Highlander II.

Yes, we have two lower ISCG-05 tabs which allow the use of a lower guide/bash. For example the e.thirteen LG1+ Lower Only Guide.

Can I fit 27.5” wheels to the Highlander II?

We have not designed the Highlander to work with 27.5” or 27.5”+ wheels.

Can I use a different shock?

Sure, the Highlander II is set-up to work with any coil or air shock. We can’t guarantee that a specific shock will fit - but there is plenty of shock clearance and the mountings are standard.
