Hey Everybody,
I'm currently working on my second frame right now and I've realized that I have not yet considered drainage in the design. Its a steel frame, horizontal top tube, lugged, and with standard sized tubes. This will be a "gravel bike." I'm hoping to get some advice on how to address drainage in the frame.
So, providing drainage at the BB is in my plan already. Probably a 7/32" hole at the bottom of the BB. Now I'm assuming that the seat tube, down tube and chain stays will all drain into the BB. What about the top tube and seat stays? I thought of drilling a hole (1/2") in the head tube at the center of the TT-HT joint, and a hole in the seat tube at the center of the TT-ST joint (see attached image). This would allow moisture in the top tube to move into the head tube or seat tube. Also, as I understand it this area is not a stress point and a hole can be drilled without trouble (wrong?). For the seat stays I'm thinking of a small hole near the bottom. These holes should allow me to spray anti-corrosion agents into the tubes yearly. Is this a sound plan, or is this something I shouldn't worry about?
Thanks in advance.
