You'll find this Spoke Calculator is very accurate and easy to use. Either enter your own measurements or select from 1489 hubs and rims in the database. Since October 2018 there has been a total of 10944 calculations.

πŸŽ‰πŸŽ‚πŸ€ΈπŸΎβ€β™‚οΈπŸš΄πŸΎβ€β™‚οΈ Oh wow, 10,000 calculations. Thank you all for using my site and trusting it's calculations. When I first started this project, my only goal was to create a website and take it from there and to see where it would lead too, after all I had no experience designing a website.

Over time I could see users creating accounts and saving their wheel builds and even more users entering their own measurements as well as using the database. To see these numbers increase has lead me to add features. Soon you'll able to calculate straight pull spokes. The other is a UI refresh.

Once again, A very big thank you to everyone who uses the site and lets count to the next mile stone πŸ€—πŸ˜€

If this is your first time here, I'd highly recommend to read up on measuring rims and hubs before entering their dimensions.

⚑ 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!

⚑ 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.
