Oehlins BM636 (S46HR1C1) is comparable to Hyperpro 461. Oehlins has 360mm between mount points which keeps bike quite high. I have ridden my friends XCh for few kilometers during our 2012 TransIceland trip: https://picasaweb.google.com/108358030893322916907/Iceland2012 At that moment I have had Hyperpro 460 and its not a way to go if you want to ride hardly offroad Standard lenght between mount points was 332,5mm which was IMHO definetly to little. Currently I have Hyperpro 461 which is much more offroad capable and Im very very happy with the way my bike is handling now. Hyperpro service and client care are outstanding.
