So I bought a 2006 GF Cake gs, 17.5 less than a month ago, and I'm not sure it's working out for me. I'm a girl, 5'7, 130 pounds with a long torso and I feel really scrunched up on the Cake GS style compared to by boyfriends super caliber. Here's the thing...if I do exchange, do I go for the regular GF caliber or do I go for the Hifi deluxe, but not in a GS version. I think I should ride a guys bike, much more comfortable. Maybe that's why I'm scrunched on the cake? Thoughts?
