Hi Nicole, thanks for the review, I am sorry you had a problem with your telescoping post. If I had known there was a problem I would have been glad to send a replacement.
You are correct, the center post cone on the inside of the original CoopWorx was taller, however we made our new mold we shortened it so it would make a stronger part when the body was rotomolded. I wasn't thinking about you having the older model with the longer tube on top when I sent your new telescoping post.
I am sorry for the inconvenience, please let me know if you need anything else.
All the best,
Tom
