Cycles In Motion 650b Randonneur

I edited^^ to ask: why not go 135mm and have a nearly symmetrical or actually symmetrical wheel?

135mm? is there's a 6 speed freehubs that is avaliable in 135mm let alone 130mm?

Also, having a wide hubs mean that the chain line will not be very even, a 120mm hubs mean that the chainset can actually be moved closer to the bottom bracket than typically.

Lastly, I also have a 650b with 130mm hubs, I used to ride it with 6 speed plus a couple of spacers, but it's not exactly a solution, in the end, I put Dura Ace 10spd on that 650b so the Cycle in Motions will have 12 speed with friction shift.
