I'm planning on widening a tiny FD cable exit hole for my Cervelo P2c, as it's making internal cable routing absolutely torturous - it's so small you cannot even fit a thin cable liner into it, nor will any tip of the Park tool internal routing kit fit into it. I'll prob get a wireless 1x etap system down the road to avoid this altogether, but in the meanwhile, I'm thinking of just drilling the hole wider.
Any tips/tricks and things to watch out for from the folks who have done this or similar?
