I've always found RM's , for a given frame size and standover, too short in the top tube for my liking - they feel like they should have an extra 25mm - 35mm of TT length.
I've tried to get on with them, but on both occasions ('93 and '06 Blizzards) had to come to the conclusion that I just don't gel with them.
A shame, because they are very good-looking bikes.
