I almost immediately replaced the stem on my PX10LE with one with a shorter reach after I bought it new. It made it even more twitchy, but it was necessary for comfort. I was just too stretched out with the original stem. I still have both stems. The shorter one is on my PA10 where it wortks fine with its relaxed geometry. The long one is in a parts bin. The PX10 now has a Nitto.
