With my All-Rounder, which has similar clearances as the Atlantis (but mine is for 26" wheels despite being a 60 cm frame, being 13 years old), the most difficult problem to overcome was not the cranks hitting the frame but the chainrings. The chain stays angle out sharply from the BB and I had to play around with chainrings a lot go be able to have the Q factor low enough. I like a Q of 140 mm, which used to be standard for Campy road cranks (and may still be so, but the last pair I bought were in 1999). Road sized ring were right out; I settled on 48 x 34 on a set of old Ritchey cranks which I bought in 1994. These are 110/74 triples without a granny ring installed.
I think the angles on the Atlantis, at least for the ones with 700C wheels, are even less forgiving than those on my All-Rounder. There is no free lunch in bicycle frame design, and every benefit (in this case, really fat tires) comes with a cost (wide Q). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
