140mm Revs in 26 variety are great on my HT and not so much travel for them to become ‘noodly’ or flexy like long travel Fox-32s used to get like.
I even ran a 150mm Rev on a 27.5 Trance last year will no probs….only went for larger diameter stanchions when I upped the travel to 160mm at the front…I used X-Fusion Sweeps which can be internally spaced down in 10mm increments for your needs, lovely fork too. Requires about 20psi less for my weight than the Revelation that was in there before, plush is often overused with suspension but in this case it’s all true.
X-Fusion stuff sits in its mid travel far more than previous Fox and Rockshox stuff I’ve used but has an uncanny knack of never getting overwhelmed or bottoming out either.
