I've been doing my first foray into wheel building on a set of Zipp 202s I picked up cheap from eBay due to the rear hub being cracked. I've rebuilt the rear with a new hub, spokes and nipples, and just about got it trued and dished with a DS tension of 110kgf
I wasn't going to touch the front, but checking the spoke tensions for interest with the tyre off, they're ludicrously high - 26 on the Park tension meter translating to well north of 400kgf (2.2x0.9mm Sapim CX Ray Spokes).
I can see nothing online about ever winding spokes up to that sort of tension but wanted to check I'm not missing something before I attack these ones. Given the level of corrosion on the nipples I expect a rebuild on the front to be necessary too but have oiled each nipple and will leave them overnight before trying to do any loosening.
