I was attending the Amgen Tour of California this weekend and got to take a spin on a BMC SL01 equipped with Electronic Ultegra. All I can say is WOW. Just a little tap to the inner paddle (the brake lever is no longer involved in shifting) and it bangs off gears quickly. What is awesome is to see the front derailleur auto-adjust to whatever gear you are running in the back to alleviate chain rub.
We hung out with the Reynolds Wheels crew, Reynolds provides wheels to team AG2R. It was awesome to see the excitement of the Reynolds crew's faces when they found out that Sylvain Georges won the Big Bear stage on a breakaway.
