Some basics (stupid questions)
Regarding the bottom bracket shell, do framebuilders modify it at all or just weld the tubes to the shell as they buy it? I know that there are a lot of different types of bottom brackets so how does that fit into building the bike and selecting a bottom bracket shell? If I build a frame, do I need to pick the exact bottom bracket before I start?
What's the best way to braze seat/chain stays to track dropouts? Do you need to notch the stays and then braze it in and fill the gaps?
Thanks and apologies for the basic questions.
