I have a 2014 (new version) P2. I recently upgraded to etap. In setting up the etap, my LBS removed the cable for RD but kept the housing tube "available" near RD and on top tube--aesthetically, it just annoys me to even see them sticking out a little. I have no plans on returning to mechanical....but, who knows I may sell the frame someday. A couple questions: (1) can I just yank out the housing? and (2) would this create a potential problem if I or someone else ever need to return to mechanical?
just save the various ''plugs'' that you remove from the bike. you can usually buy replacement plugs from, among other places, excel sports (and any cervelo dealer)
