I've got a battlecross X30R on my modern bike and it has been the best tyre I've used on the rear for a long while , for trail riding it grips well in all condition and has done allot of bush km's and worn well , can't comment on the fronts but the Dunlop geomax32f on the front is my choice at the moment I've got them on a couple of my bikes both new and old , they work well in the otways slop and the high country rocks. But tyres like oil are controversial to comment on so its just my 2 cents
