great shock, lots of rebound adjustability and the threshold adjust really works too....
however, mine is on the shelf as i replaced with a 57mm CCDB which is sensible for the trails i generally ride. for xc/am , the 4.2 is an EXCELLENT choice, with more adjustability and 'envelope' than the RP23...........
