Query: Was fine until half of it fell off in the woods.

The lower extension cinch bolt worked loose while riding, and the lower extension fell out and is lost forever.The extension ought to have had a stop to prevent it from sliding all the way out of the upper tube. Having to keep a kickstand tightened to prevent half of it falling else is absurd- I'd rather it just came long and they had me hacksaw it to length.
