I just got a new rim, measured the ERD and fed it into two different spoke length calculators:
And I get different results. They each ask for a slightly different set of input data, but I've tried very hard to supply accurate info to both as measured directly from the hub and rim using the the best tools (laser ranger for the rim diameter; vernier gauge for the rim thickness flange offsets etc.); but the discrepancy between them seems a little too large to ignore.
Which would you use?
