You'll have to ask them what sizes are available, I use off the rack cables for other bikes on my builds. Used to have the Motion Pro catalog almost memorized, shop had dozens of each cable in a rack to play with.
They might want to know how you heard of them. I took a couple years off from Do The Ton, but since I'm back to working on my street legal tracker I restarted my membership.
