I had a pair of Rev RCT 3 on my Orange 5, and while they were a good fork and I thought they were reasonably stiff, the 34mm Trace feels a bit more direct and less bounced off line in the rough stuff, and that’s with a 29″ wheel over a 26″. I was wondering if 120mm travel would be enough, and after riding Laggan black yesterday on it, I can say it is plenty and shouldn’t require more than that. It turns really sweetly at 120mm. I think if you fit a Rev you won’t be disappointed, and as you say, you can drop it internally if you feel the need.
