Just a note... it's almost impossible to do a fit without clipless pedals and shoes. When you walk into a LBS and ask about a Sirrus Sport or Detour 4.5.... sorry, but a "fit" doesn't often come up in conversation. A road bike or mountain bike.... hell yeah. Chances are if you're even considering a Detour 4.5, a long ride isn't exactly on your main goal. Therefore, fits aren't that important. Buy a Sirrus or Detour 4.5 and want a fit? It should be taken care of for you.
