Will my spokes fit?
Ping tuner: what each side should sound like
Pluck each spoke between the rim and where it last crosses another, and match the note. Every spoke on one side should sound the same. It's a guide to even tension by ear, not a tension meter.
Often needed with this wheel
- A Garbaruk cassette
Lightweight 10-52 and 10-44 options for XD, MicroSpline and HG freehubs.
- Nextie carbon rims
Every Nextie rim is in this calculator too, and I can build any of them into a wheel for you.
These lengths come from the makers' published sizes and a standard sum. Rims and hubs vary from batch to batch, and sizes you put in yourself are only as good as your measuring. Travers Bikes takes no responsibility for spoke lengths worked out with this calculator, or for spokes, wheels or parts bought or built using them.

Want me to build it?
I hand-build wheels in Rochford with Nextie carbon rims and Hope, DT Swiss, Chris King, Shimano, Nextie and SON hubs. I work out the spokes and order them, so getting the length right is my job, not yours.
