it won't be a change to Ulysses/X model. I can't remember the suspension specs of the Ulysses bikes (around 6" travel? can't remember) but this stuff is just going to take it to the same travel as the SX bikes. I think it's only another 1"-1.5" of travel. been so long since I've had the specs side by side, but my aim was to give it the suspension travel of an S model to make it more supple and compliant around town. despite tuning, I still find the bike a bit rough and twitchy on irregular roads.
