Due to the belt pulleys being larger than sprockets, the gearbox will have to be widened by about half an inch +/- .125". Although it will take some machining to get this done, (some very basic machining) I see it as a benefit rather than a hassle. With belts rather than chains, after they are set since it is exact c-c you never have to touch them again unless something bad goes wrong. like thrown belt or ratcheting occurs or other issues caused usually by human error. I forgot to mention I added .003" to the c-c distance to get the tight fit on the belts. But I have seen some very good and bad things said about belts. Mainly good. So I am giving them a shot. I put the WCP WCD gearbox in there because it was built for the type of frame I designed so it was basically a plug and play. I guess you could try and use the regular WCP shifter but I didn't. Glad I could help.
