The Spoke Calculator is very accurate and easy to use. With 1497 hubs and rims in the database, you can quickly select your chosen parts or enter your own measurements. Since October 2018 there has been 9571 individual calculations.
You can save any wheel build you create on Spoke Length Calculator which includes custom measurements or any make and model selected from the database. There is also the option to add any missing hub or rim measurements to the data base too.
In fact, there are quite a few older models with missing information. If you should come across any of these, when build a wheel, I would appreciate if those details can be completed.
If this is your first time here, I'd highly recommend to read up on measuring rims and hubs before entering their dimensions.
Be advised, you may find hubs which use straight pull spokes. At the moment please do not use these as the spoke length will be incorrect.
⚡ As a precaution. When selecting a rim or hub from the site, it's best to double check the measurements with your items first. This isn't a warning to say the calculation will be incorrect, because it wont be. It's more to do with intolerance between published and real world measurements. This is mostly true (pardon the pun) for rims as being out by 2mm or more can be the difference of having the right length spokes or not!
- The site has had a couple of updates. The main one is, you can now add images to new and current hubs and rims within the database. This Hope RS 4 hub is a good example
- The server code has been tidied up and you should notice a speed increase when pages are loading.
- The hub and rim measurements page has been updated. Why not go and have a look? These include a new and easier to view colour scheme and a couple of fixes to server code when searching through the database, which means you'll be seeing less sarcastic error messages too.
