Mikey74, I ran Revs at 150mm when I first bought the frame, good choice!
Only reason I went to 160mm and changed to X-Fusion was for the added axle to crown length and the effect it all has on the head angle of said bike, the front of mine now looks slacker than the 66 degrees Giant state for the SX model.
It works for me while keeping the (relatively) short travel 140mm of the frame itself which retains the decent pedalling nature of the DW/Meastro link rear.
Think Nukeproof Mega TR with its mismatched travel (150/130) and you’re there or thereabouts with what I’ve created….Transition do a bike like it too, Ragley tried to launch one like it, the new Orange Segment has a similar ethos…for diehard hardtail fans like me it makes more sense than 160mm at both ends.
