If you really want one, let me know. I can send one to you from the U.S. With that said, Sim Works do ship internationally - sim.works . I don't know how much it weighs though.
Seems that the availability of sizes of the stem on the website is quite low sadly - nothing above 70mm. I was keen to get one too for the DBAD i got of amey.
Lovely bike/build, your changing my opinion on those cranks - they look really good on this.
A shame the Sim Rhonda is a ball ache to get in the UK, would like one for a current build. How heavy is it?
