Hi,

I have a similar problem - how did you resolve the issue?

Don't have an Atom... but if it were mine I'd sacrifice some beer cans and just shim it.

Hi,

You can't shim it.

In all of their wisdom, Wattbike put a rotating end cap on the bolt that secures the seat post, so when it's clamped tight, it pivot on that bolt.

Even if you shim it, the post is that long and the seat tube so much wider, it still pivots on the bolt.

My solution was to buy some sticky thin felt strips that go on the bottom of furniture feet when you have laminate or wood flooring. I then removed the seat post and stuck a strip of this felt on the inside of the seat post on each side.

Hope that makes sense.

I emailed Wattbike several times, but they weren't interested in a) their design fault and b) my solution.

Regards,

Pat.
