Yeah I’d say overall length of the steerer sleeve for stack. I’ll put the extension tube as close to the top as possible, maybe 5mm down from the top to allow for the fillet, if it’s a 31.7mm tube that’d put the centre of it about 21mm from the top of the steerer sleeve.
Ok, sounds good. I should have the frame beginning of august, then my LBS will transfer parts over, and I’ll then get the bike ‘re-fit’ to me. At that point i’ll know what extension and stack I’ll need and give you a shout? So mid-late august I should think.
Smoothed would be really lovely please, ala https://www.lfgss.com/comments/15347021/
I like the slightly narrower 'wrap' of the middle one in the preceding post, and the bolts on the back of the steerer
Stupid question: i assumed the stack measurement (as given e.g. for VO's tall stack stem) is bottom to top of the steerer sleeve, is that right?
