remove cable guides above BB shell?
My fellow C&V members will probably banish me for asking these questions, but here goes:
Background: I recently picked up an 80s Chicago Schwinn Traveler frame with 4130 tubing with an included Sugino crankset on-the-cheap. One of the cable guides on the top tube was already removed and the larger 52 tooth chainring is badly bent, so I'm thinking of trying to build it up as a SS/FG conversion. I understand that the cable guides are often removed from the frame for a cleaner look.
My questions are about the large cable guides brazed onto BB shell.
1. Would you remove these large cable guides?
2. If so, how would you remove them, without messing up the frame structurally?
Although this is not my bike, here's an example of the kind of guide I'm asking about:
83 Schwinn 'Graveler' * 87 Trek 560EX * Sanwa SS * 80s Schwinn Traveler SS/FG * 90s Trek 830 * 2011 Fuji Sagres 2.0
