Spoke Calculations are driving me crazy!
32h PX Pista Hubs and Ambrosio Excursion Rims. 3x for both.
Online the ERD is given in various places as 600.5mm, my tape measure says 595mm for starters.
The hub data given on PX is useful I guess, but doesn't meet the measurements the sites are asking for.
So, using my values (expect ERD on the Edd site where the rim is in the lookup table) I've got the following results:
Sapim
Front & Rear 293mm
Wheelpro
Front 284.4
Rear 284.8
Applied Thought
Front 287.65
Rear 287.49
Recumbent
Front 290.457
Rear 290.299
Edd
Front 288
Rear 288.3
So, no consitency. What's the margin of error for spoke length? I can't imagine it's more than 1mm or so if tension is to be correct.
