Currently running a Conti X King 2.4 front & Race King 2.2 rear and am happy with grip and rolling resistance but am going to try some tubeless ready tyres on my UST rims. I get quite a few punctures at the back. Cant really bring myself to shell out 90 quid on 2 Conti protections so am going to give Bontrager a go. What is the Bontrager equivalent of a Race King, XR1, XR2 ? And im assuming an XR4 up front? What Bontrager tyre combo are you running for the summer? Oh and mainly using them for Gnarr type day rides 20-40 miles in deepest north hants…..
