Anyone ever run a Sturmey Archer SRC3 (3 speed coaster brake) to a Schwinn S7 26 inch rim? What length spokes did you use? Spoke calc isn't working for this combo and my spokes are way too long.
Go here and enter your actual hub and rim measurements...in millimeters....should be able to calc from here...
There are other sites, but find one where you can plug the dimensions of the hub and rim into the auto calc
function....gotta measure actual with a tape measure...
