Some trivia about 120 mm spacing: many of the typical 120 mm SS hubs have a 130 mm version available that has the same hub body on a wider axle and the same 42 mm chainline. My White Industries eccentric flip-flop hub is 135 mm with a 42 mm chainline on the fixed side.
In other words, there is not necessarily a difference in chainline in the different width hubs UNLESS you're using one of the 135 mm SS MTB hubs on the market. If the chainline is 42 mm, regardless of overall hub spacing, you can use the same narrow BB and narrow-tread crank, provided the chainring and crankarms clear the chainstays. 120 mm is only an advantage if you already have a stash of hubs/wheels in that size and/or you believe that maintaining "traditional" dimensions is important and/or you want to run genuine track-bike parts (which Riv doesn't). 130 mm or 135 mm would give the added advantage of being capable of accepting a cassette hub with a spacer kit and 1, 2, or even 3 cogs. Not that 120 mm spacing detracts from the coolness or quality of Riv's SS attempts - just trying to point out that the argument for/against one hub width dimension and another is not one-sided. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
