Wheelbuilding / Wheel Building / Wheel build help

Jason from Yishunbike gives me a time of 3-4 weeks for the 'custom drilling' and asks me if the 28h rear is for a disc brake build - it gives me some small confidence that the salesman asks about the purpose of the customisation.

Buying non-reviewed 2015 line-up rims is a gamble, with a good gut-feel as the main carrier :]

The thing is it's a fixed gear, so realistically you won't have problems with overheating, delaminating etc... that rim in the photo split open coming down after 2.5 miles of a 9% descent... nothing of that sort in London.
