Scooper, great pic but notice that there is a _slightly_ larger margin of error with the 12 mm. if you're off by about 1 or 2 mm too long with the 14 and 16 mm nipples, you'll have the nipple start to cut new threads into the spoke. those new threads will be a point where failure could occur.




dwoloz, is the wheel you're talking about using a single wall rim?



Sammyboy, if you're hub and rim dimensions are accurate, you'll be fine if you round down to the nearest whole number.
