I already went to one, but everyone seemed super busy (it's that time of the year when everybody and their grandpa starts riding bikes) and when I finally got to talk to a tech, he was not familiar with the Versa shifters and was wary of poking around in something that was not purchased in the shop. I don't really blame him. Alas, the downside to buying parts on the internet at bargain prices is the lack of support. I emailed the company that makes the shifters, so we'll see what they say.
