The Rune isn’t that Porky and it pedals really well – for a biggish, silly bike it climbs really well. In fact that’s what I’ve been most impressed with. I knew that it was good descending, but I have genuinely been really impressed by the way it climbs.
Mine is 33lbs (may be a bit lighter now the Van RC2’s have been changed). Large, Bos Devilles, Havoc wheels, Hans Dampfs (tubeless), 1×10 X9/0 etc. I’ve used mine for everything from XC rides in Swaledale to uplift days at BPW and Antur plus most things in between including riding in the Peaks.
I’d vote for a carbon SB66 and would have one if I could find one / afford it.
