Does anyone know where I can find spiral spokes for the 17" rear wheel on a 2012 wide glide? Found the 21" ones for the front no problem, but the only site I could find with 17" spokes wants like $200 for the set.

 

That's about the price you're going to pay. Buchanan makes them, I've bought a couple sets of regular spokes from them and have had nothing but awesome service. Called them many times and they never steered me wrong.
