I had a 56cm 1993 RB-1 (which died when a Volvo C70 broadsided me on a residential street). So ok, my impression that the Roadini is a taller bike makes sense. When I first talked to Will he thought I would fit a 57cm, but after I told him my intention to use drop bars he went and remeasured the bike and decided the 54cm made more sense. I'm glad I didn't go for a 57! Clearly bike sizes are like shoe sizes --- they seem to change year to year even from the same designer! I did give Grant a hard time for not making the Roadini a 80mm BB drop bike like the Hilsen. (The Hilsen wasn't a consideration --- it used 135mm wheels, which I don't have, and the chainstays are even longer --- the Roadini's long stays already make certain sharp steep climbs not as much fun to ride!) My thoughts are that with the trend to larger/wider tire sizes BB drop should be even lower, especially for those of us who aren't aggressively pedaling around corners. But Grant rides fixies and he pedals around corners so I'm going to lose that argument every time.
