My husband and I went to Trek today to look at the FX 7.2 for him (I just ordered to 7.2 WSD for me last week.).
He is 6ft 1.5" tall.
He loved the bike....seems to be between sizes though (22.5" and 25").
The guy at the store was steering him towards the larger...thought it fit him better.
He has not ridden a bike in over 20 years....so even after test riding, he was not sure which one felt better....
