Riv definitely made the 50cm Betty, because I have one! They used to make 47cm/52cm/58cm (and possibly one larger size?), then at some point they switched over to 50cm/55cm/60cm sizing. It's similar to the Cheviot sizing now.
I've seen a couple Betty's come up for sale on this site the past year. If you like the Cheviot design I believe the 50cm Betty and Cheviot have the same geometry, while the 55cm/60cm Cheviots have longer chainstays than their Betty counterparts. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
