I’ve used single pivots (Orange Sub 5, Orange Patriot, Marin somethingorother), Horsts (Spec. Big Hit) I-drive and currently Giants Maestro (DW link equivilant) on a Reign.
Of the (admittedly very varied designs and intended uses) bike’s I’ve owned I wouldn’t swap the Reign for any of them, with the pro-pedal on medium I can pop the bike off small lips/drops, on it’s low setting I can blat down loose peak-style rubble descents and on full I can climb as well as I am capable of.
6″ rear travel, 140mm front, big grins and high recommendations!
