This is a cheap replacement. They are called the trekker and I know Fairhaven bike and ski sells them. Never actually used them but heard some mixed reviews.
Unless you are trying for the whole set up.
I hope Like a Lion can really change people's opinions on Tanner forever. I'll admit that I used to think Tanner was some idiotic asshole who didn't know how to act, but he's just another person with highs and lows like anyone else. Mad vibes and prayers to Tanner, skiing loves you just as much as you love skiing
