I am not that big...About 5 foot 8 160 lbs. Never bottomed out the fork. If you really try hard to drive the back end down you can just feel it hit the bump stop, but it could likely be stiffened up with the shock settings....i like the set up. Seals are good and comes with a spare set of seals for the shivvers and about 3/4 of a liter of oil. the burp screw on top of the left stanchion leaks a bit of oil, if a guy could get one from marzhocchi it would be completely sealed. i tried to find a seal at the hardware store,but they dont have any that small.
