Now that I have some hubs figured out ( thanks all who weighed in), now I need some spokes. Last wheel I built was when I had access to a Sutherlands. No more.


Anybody have experience with Edd, A spoke length calculator, https://leonard.io/edd/. .?

spocalc and edd - I've used both, and both have worked for me. Always good to take your own measurements to verify their input data, though, particularly rims.

+1 on checking the measurements, especially the rim's ERD (and don't forget to add in the thickness of the nipple heads).

I'm writing from memory here but IIRC I've used both of these programs. For at least one rim I found an error or an ambiguity or something re ERD that made me dig up the other program, found the same problem even down to the same wording. It made me suspect that one had "borrowed" the database of the other, or they both "borrowed" the same database from elsewhere. In any case, the ERD is by far the measurement on which spoke length depends the most. It is worth checking.

+2. The various calculators are generally using the same equations, having good measurements is key. Some account for spoke stretch, but I don't think spocalc does. So my "measuring spokes" only have the spokes threaded flush with the screwdriver slots in the nipples.

thanks so much for the suggestion on checking measurements. The spoke lengths I was getting fron Edd seemed a bit long. Was able to duplicate them on prowheel builder. But....that was with a 130 mm hub. And I am building with a 126 hub. Edd doesn't let me spec OLN dimension. Sapim does. I will double sheck my measurements then if I can get two calculators to agree, I will go with that.

This is by far the best SLC I've used:

and btw the book is fantastic too

I agree that Wheelpro pdf book is well worth the money! Years of wheel building experience recorded in words. The nice thing it's on your computer immediately, so no waiting for a paper version to arrive. As someone else said above most all the programs use the same formulas so the choice is pretty open to your own preference. I currently use the DT Swiss on-line version and just set up a free account to remember past build numbers. So far so good.

Seconded. I printed out an spiral bound a copy, which is handy... but I see there have been three new editions since then!

You can download the updates for free too!

I've used EDD a bunch when building all-vintage wheelsets and have found it to be accurate.
Sometimes you have to look for an 'equivalency' hub (e.g. almost all mid-late 80's Shimano hubs have the same dimensions).

As others have mentioned, correct rim ERD is critical, and this is where EDD falls down when working with more modern rims and vintage hubs. It just doesn't have a lot of modern rim information in the database.

Also need to make sure you identify the correct rim, as some of the model names and numbers in the database are a little off- recently had to double check some dimensions when lacing up a set of 70's Record hubs to some Wolber Alpine rims, and there were multiple possibilities in the database.

Yes, I've done that for a couple, but haven't printed out another copy. Actually, for my purposes, I don't think there have been any major changes since Ed 4. (I reserve the right to be wrong!)

It's handy to have a hard copy... mine is annotated for my own porous memory!
