Rod_Saetan":3jdur1ip said:The 89 catalogue seems to imply there is no difference, and as the tubes are triple butted I would question whether you'd bother to do that to a seamed tube, especially when you are already making the same frame with same lugs for another model. My '89 is RB2 is not seamed tubes, I haven't actually checked my '91. I don't have a definitive answer.
