Shimano steps range extender

[RRebikes]

I mean that I saw a post on Instagram of a company that was selling range extenders for the Shimano steps. I believe it was either an Italian or Spanish company.

Anyone else seen this post or now anything about a range extender for Shimano Steps?

I can't find the post on Instagram, and no results on Google when I do a search

I know this company sells it, but I have not tried it
