Donnelly’s X’Plor adventure tire series is designed to bridge the gap between pavement and blazing your own trail. Each tire within this series is designed for multiple conditions from off-road touring, to gravel racing, to just getting outta’ Dodge.

I bought this as a front tire to pair with a 47c Donnelly EMP in the rear. The non-aggressive tread has great rolling characteristics. The 50mm wide tire patch coupled with a pretty soft rubber compound make for plenty of traction, and I think that any additional tread (especially for a front) would be overkill. I only have 36 miles on this tire, so durability of the softer rubber is still TBD, but so far, I'm loving this tire for all things gravel.
Love these tires for rough gravel roads. I have 650Bx42c and they are way better than other tires I’ve tried. I racked up half a dozen flats on a couple different sets of tires so I decided to make a change. No flats on these tires yet! 200 miles logged
