Wheel building question...(6 posts)

Wheel building question...PT
Oct 28, 2003 7:36 AM
I need to get the spokes to lace a 32 hole, 3x, aerohead rim (700c) on a ritchey zero WCS hub. Spokecalc specifies spoke lengths of 293.3 and 292.7 (left and right side, respectively). Can I just get one size of spoke (293), or do I have to round up to 294 on the left side?

Thanks!
293 will be fine....IDH2

In my experience, anything less than 1mm is negligible.
How about 294?PT

I'll probably order them from performance, and they have 292 and 294 listed, but not 293... Will more than an extra mm make a difference?
I think you will be fine....IDH2

I build-up a set of dh rims with a 3mm differential - split the difference and it worked out fine. I'm almost afraid to suggest this so openly, but I'd go for the 294 and if need be, modify...it's really not a big deal ime.
293, 294, what ever it takes =)nmpitt83

what spokes? which spoke calc?cyclopathic

I'd rather go with 292. Some spoke calculators do not take into consideration spoke stretch, and if you use DT Revos, Wheelsmith XLs or DBs, with proper tension spokes stretch more then 1mm on drive side. I'd rather have spoke short then not being able to put enough tension. BTW JensonUSA has WS DB spokes for .25$ and straight for .15$. They're slightly lighter then DT (1.7mm vs 1.8mm), yet strong enough.

Try this calculator, it is very accurate (but you'd have to pull data from other sources) http://www.appliedthought.com/danny/Spoke/SpokeCalculator.html

PS. have you considered half-radial vs 3x? it actually makes rear wheel stronger
