I bought an older (mid-eighties) univega touring frame to build up as a commuter. To my surprise there is no tapped hole in the bottom bracket to mount a shifter cable guide plastic doo-hickey. (don't know the official name of that piece)
Q1: Are there any other options besides drilling and tapping a hole to mount one of those under the BB?
Q2: If no other options, anybody know the proper tap size?
