Sledjunk, I guess the tuner ski piece isn't as robust as the old school one. Those were bulletproof. 5 seasons, no issues.
On the Rollerskis, I should have taken pics.
There's a very coarse thread where the pivot bolt goes through the mounting plate. Looks more like something on a jar than on a fastener.
No way to repair it. Due to galvanic corrosion (?) there was a fair amount of metal missing.
Warranty is 3 months.
Roughly $143 per month.
