Hi all,
Help!
I'm preparing to build up a set of wheels and have a question
regarding spoke lengths. More specifically--what are the proper
lengths. The rims are 700c 36 hole Mavic Open Pros. The hubs are
Shimano 105s. Using Spocalc, it tells me that the front spokes should
be 294.8mm for a 3x pattern. The rear wheel needs 292.4 and 291.3mm
spokes for the same pattern. Do I round up or down? Jobst's wheel
bible states that spokes stretch. This would lead me to want to round
down but should I? Wouldn't it be better to round up? Is a fraction of
a millimeter that critical?
Thanks!

not a big deal. The fraction of a MM is not going to make a difference.

I round up always. .1 to .9, round up using DT spokes
