I noticed the toe strap adjustment lever popped open after a steep run on some untracked sticky stuff in one of my secret stashes on cypress last night. Not a big deal, didn't even notice until I got to the chair. But hopefully it doesn't become a habit or I will be epoxying those things in place.
Otherwise, the honeymoon with the nows is still in full swing. Loving the ease of boning things out no hiback style.
Samething happened to me; it didn't come completely undone but it was loose after my second run.
Also, need to apply some loctite; first time ever while riding, the screws came loose.
