I see it more from guys running suspension too soft.
I have three sleds with Alpha rails, one is a conversion. I wheelie, jump drop and abuse them on shallow snow riding areas with no maintenance roads for access on my way to the local mtns.
All three are original rails, over 7500 miles combined.
Zero rail issues.
I have broken a chain case and a brake rotor slamming stumps and rocks.
I also weigh more than most everyone who will read this.
luck?
Ive read talk of guys bottoming out their Alphas, this is where I think most the damage comes from soft suspension.
Big as I am I’ve never bottomed any of mine out. My 15 I did quite often. I still have a great response from my suspension, never feel beat up from being too wound.
I know there’s plenty of broken rails, but FWIW I’ve replaced many broken twin rails over the years.
Now I’ll probably snap my single rail first ride this year…..
