MrS.
Isn't this a rather odd burry-head-in-sand approach to bike kit?
The XC Pro is a sound general purpose tyre, but boy, are they draggy! YOu can even them them dragging.
Jim: The idea that you can afford to run a bike, riding kit, feeding, hydration, spares, servicing, any upgrades, replacement pads, lubrication, tools, accessories, replacement moving parts, esp' rear cassette, front ring(s), chains and all that jazz – but not own 2x sets of tyres is utter nonsence. FFS OnOne are selling theirs for a tenner.
