I would be a bit peeved too, the least they could do is call you and ask you if you want the gel replaced while the bike was there, or tell you that it disintegrated. I am a firm believer that you return something to the owner in the same or better shape it was given to you. Not changed.

And Liza, I think she is talking of 2 seperate bikes, the Ruby is the one that was changed (and keeping) and the Sequoia is the one she had previous gel issues with (and for sale).
