Well I requested 373mm a-c but when I mentioned that I wanted clearance for 32mm plus guards Jacek said that to achieve that it might be a few mm more than 373 which I am happy with, don't think it will affect it too much.
I originally said clearance for ~700x38. I might have been able to squeeze 32 and guards in with the original geo but obviously a frame builder wants to err on the side of caution with requests for clearance.
It will be made from 631 blades, I guess it will probably be around a kilo, not too concerned about weight.
@jaeyukdapbap I love that paint job, wish I could have got one of those.
