Read a lot of fixes for this, but WHY? Why after spending what we do on these trikes do we need to go to home depot for a fix of a known problem? It is a KNOWN problem that for some reason the factory can't or won't fix. I read one post where you can buy, YES BUY, another clamp to put behind the slipping one!!!!!!!! I put a c-clamp on mine, looks like crap but when asked I sure as hell tell them why it is there.
