streamline billet, rebuildable 7 way adjustable on my sig bike
before that, and now on my black bike as of saturday, an old denton stick,
i don't actually race, but not sure if the way, and where i ride would be considered sport ??? does there actually have to be other competitors to be considered a race ?? LOL
i adjust it regularly for conditions.......
if i'm riding smooth, easy trails (rarely) i set them maybe 1-2 clicks from the easiest setting
if going on my usual "rough ride" i set them dead in the middle, then if i know a particularly rough section is coming up, i lean forward and turn them full on
but...be careful with them set "full on" at least with a streamline, the denton is worn so doesn't matter as much,
once on a very steep rocky hill, i hit a rather large rock, which shot me to the left, and i had a very hard time turning the bars quick enuf to avoid almost going off the edge of a very steep embankment
i think slick has video of that somewhere ??
on a new, or properly functioning stabilizer, the mid settings will do most of what most riders will need
... Also interested if it's a race or sport application ... stick or puck
