It would be very different, they say they revalve the main piston, so right there a good change, but they completely get rid of the propedal internals and put a high/low compression adjuster in it's place. You can get a much better tradeoff than with propedal. As far as bottomout, it's a function of the bumper, the reservior pressure, and your leverage rate. One of the issues with the DHX is that it tends to spike a bit at high speed, this is caused by the restriction of the propedal valve.Uncle Six Pack said:
