My new-to-me bike is the first I've owned with 700c wheels, and the wheelbase is 45". The first time I used the Fort Worth bus bike rack the driver said he didn't think it would fit. It was a close fit, but it works. Occasionally the bungee cords inside the telescoping wheel hooks feel a bit loose, so I keep my own bungee cord or Velcro strap handy to secure the wheel in the rack. Nothing too elaborate or time consuming. So far, so good. Probably a good thing I didn't get the Electra Townie I had my eye on - the much longer wheelbase probably wouldn't fit the bus rack.
