You guys who feel they're just fine... that's great, good on ya for not having problems.
I'm sorry but my 09 was not my first M & actually has been the lowest riser I've owned on a sled so far. They all may bend or break, but NONE will bend or break as easily as the adjustable ones. Also, if you put a riser with some type of ability to articulate, you're hugely less likely to snap or bend them.
As for the anti slop bushing, that will HELP a bit, but being as how it's able to move in any direction, it's not going to stop posts from breaking. I think it's worth the $60 or whatever, but it's not going to fix the problem.
Oh, and if you're a hillclimber, or you just ride around in the meadows, or you never leave the ground (how one could do that I don't get)... big surprise that they don't break. The reality is that some people ride harder than others, this doesn't mean they're BETTER, they're just harder on their stuff. (you sally longtrack riders probably don't have any problems!!!
)
I ride hard, I got sick of fixing posts, I changed to a different type of post, I've had no problems since. (and my sled went flipping down a 2800 foot chute at the end of the year, it's taken a beating since then!!:face-icon-small-sho)
Oh, and since we're comparing vital stats... I'm 5'7-9/16" & 180. It's not what you weigh, it's how you ride.
