Funny..... My original idea for my BB was a cut out. Told me this wasn't possible. He also said something similar in the thread about it a while ago. I guess he just picks and chooses what's possible or not depending on the mood he's in. Looks like it'll be a nice build!
My original design called for a notched BB and ST. He told me it was structurally impossible to build. It's been done on a few track bikes which is where I got the idea from.
A curved seat tube would probably work better, but you'd have to have an integrated pivitol post thing like the NS capital, because a seat tube wouldn't go in unless it was also curved...
I understood what you meant.. sorry I didn't make myself clear. One better than a notched seattube would be a curved one. You could go really short then...
(Mattty) from stout bikes has produced some beautiful metal work. 83mm spanish bb with scallop to allow for 350mm (13.8in) chainstays. Absolutely nutz.
So pumped. We ended up deciding to do a slightly flattened (i dont remember the size, i think 3/4) chain-stay up until I no longer need sprocket clearance. will be so dope. check out the "Ultimate summer grant" thread for updates yo-
