That's a good question. If it will be sold with the SA hub, then probably 120, as SA says that the hub will be 120, but maybe a second @ 130. My concern would be if the 130 is just the 120 with a longer axel, which would make for a crappy chain line on some frames. Still, Pashley has been doing some cool stuff so I think this bike makes a lot of sense for them. I think a bit of refinement and a front brake and I'd consider it. It looks like a lot fun.
