Clement X'Plor MSO 700c 40mm
The Clement X'Plor MSO is probably one of the nicest readily available mixed terrain tires. The dual compound rubber allows the bike to zip along on pavement and grip like crazy on gravel and dirt. Ride to a mountain, then up and down it on dirt! Or use them on a mixed terrain camping trip! If your bike can fit this big of a tire, you are stoked. Mounted to a 23mm rim, width at 45-50psi is 39-40mm, so pretty true to stated size.
