Hi,

I'm a long time lurker, first time poster. I recently upgraded my 2013 Shiv Comp (bought in Jan 2013) to Ultegra Di2. I had the LBS do the install. They installed the ST-6871 brake levers with Di2 switches with the wires taped to the bottom of the base bar. When I asked about it, I was informed that the aluminum base bar does not contain the necessary ports to route the Di2 wires inside the base bar along with the brake cable.

Is this true? If so, why did Specialize not include ports on the aluminum base bar? The frame is otherwise completely set up for internal Di2. Is there any (safety) issue if I drill holes, for a cleaner Di2 install?

Otherwise the install is pretty sweet. The LBS advised me of the new Specialized adapter for the seat post internal battery mount, so everything else is neat and clean. I didn't upgrade the drive train, so I stuck with the older 10 speed (and cheaper) Ultegra 6770 Di2. I really like what Shimano has done with E-Tube, with everything being plug and play interchangeable!

Thanks!
