The xr1 lasts pretty long. This one is running onto 3 years and it's been used for XC setup as tubeless, about half a year on a street bike, and so far just a few weeks on the streets now. I can't compare to the Raceking, but the XR1 tread looks tons smoother than the Raceking.

 ok sick! cheers mate What width is that and how wide does it actually come up?

 I use a 2.2, also comes in 2.0, but the 2.2 is about a 2.1.

 Thanks mate, i just want to slam it in my octane one void and the race king i a bit bulbous for comfort

 Well...That's because I clean my garage.

 Yeah I clean mine too, it's organized but it's just packed with stuff.
