Some Help with Spoke Length

Hi,

I’m going to be building a new muni wheel soon and I’m getting some conflicting results from online spoke length caculators.

The wheel components are as follows:
Alex DX-32 26 inch rim, 36 hole, ERD is 550
Unicycle.com wide hub
14 guage spokes, built 3-cross

The Unicycle.com calculator gives me a spoke length of 262.64mm.

The United Bicycle Institute calculator gives me a spoke length of 270.3mm.

Can someone run the numbers through a different (or the same) calculators and see what they get? In the past, these two calculators have been very close in their results.

thanks a bunch… Mojoe

That’s funny, I just got a Uni.com wide hub this afternoon and I’ll be building the same wheel this weekend. Go with the 262. number. I built my Profile 26’ wheel with 262mm spokes and the Uni.com hub has a slightly larger flange. The Suzue flange is larger and I’m pretty sure that combo uses 260mm, so Roger’s length sound good to me.

Thanks Frank…

recheck your numbers

Mojoe,
Recheck what you entered @ uniteds web site.I came up with 263.2. I built the same setup and remember getting numbers in the same area when using DT`s spoke calc. chart and uni.com. Also remember that uni.com uses the hub flange to hub flange measurement and united uses hub center to hub flange. Which would give you 270.3 if you used 71.3 for the hub center to flange measurement.:wink:

bam,

You’re exactly right. I overlooked the hub measurement, thinking it was flange to flange.

Thanks a lot! I feel better knowing why they came up different originally.

I’ll go with 263’s.

cheers… Mojoe
