Lugged BB Angles
Happy New Year everyone!
Very novice framebuilder here, I built one at a course last year, and I'm looking to build one on my own this year. I'm fairly short (5'3"), and I'd like to build a lugged 700C racing frame.
So, I'm running into probably the normal challenges of designing a small frame with large wheels. Even after drawing out several options, I found that my ST/DT angle is very acute - 56 degrees. Most of the BB shells I've seen online are about 60 degrees.
Is that too big of a difference?
Or is it alright to pull the DT port downwards when fitting things up? I recall doing this for the chainstay ports, with the instructor saying "they never fit right, just pull them downwards until they fit right".
Thanks!
James
