Ready for the tyre when the wheel is built.
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.
