I Probed My Bike
I’ve been recently changing my personal fleet of bikes from 1x to 2x. Perhaps the bike that has been giving me the biggest headache is my Bearclaw Thunderhawk with internal routing. In this video I use a $30 endoscope to see what sort of shenanigans are going on while I try routing the cable housing.
Hey Russ!
regarding internal cable routing: I was having a really difficult go of trying to thread the cable through the top tube, when I re-oriented the bike so the top tube was vertical, inserted a length of fine sewing thread, then sucked it out of the exit hole using a shop vac…it was quick and easy, after I attached a carefully trimmed toilet paper cardboard tube to the end of the shop vac hose so it nested flush w/ the round section frame tube.

ps. I really enjoy your website & videos!
I distinctly remember being able to find interior steel tubing for routing housing through a frame, and I think some forks with internal light wiring have something like that going on too. I can’t find any now, so maybe that was a fever dream. I suppose commonly found 5/16″ brass tubing would do. I wonder what the disadvantages of that approach would be other than the added weight and a little more cost in materials and labor.
