can any double cross owners comment on fit of this frame? trying to decide if i should get the double cross 54 or 56 for credit card touring and brevits with some off road duty with a second set of wheels. so we all know the double cross has a long top tube. i usually ride a 56cm bike with a 56 or 57 top tube. i have a smoothie es 56 that fits well. i am 5'10 and 1/2, with a 83 cm pubic bone. long torso.
