In the last year I have used
Lyrics, 36’s, revs 15mm & 20mm, marzocchi 15mm and reba 15mm (current) The only real difference I could tell between is really the 35/36mm legs on the bigger forks making them stiffer. Made no real difference to me on the revs and I found the reba ‘s the stiffest of all the 32 legs(less travel I suppose) all except reba had 203mm rotor on.
