Hi guys... I have been riding this fork for over a year now on our trails. Fitted to a Cannondale Flash Alloy 29er. Welvanpas, Jonkershoek, Meerendal, etc... No problem. I am not that fast a descender, but I am no slouch either. This fork is more than capable, and un-adjustable rebound not an issue. I just learned to choose my lines better. Climbing and out of the saddle performance is also great.
