I had to stop to think, but now that you mention it, I don't scrunch up much or often... except when I first start peddling. I'm at a stop and go stage right now, building my stamina, so I'll bike about a mile or two, but I'll stop a few times during that period. When I first start peddling to get it going I do scrunch up a bit, it almost feels like my thigh is hitting into my lower torso. I kind of assumed that would just happen until I lose some of the belly.
I'll be heading out Sunday or Monday to talk to the guys at the local shop. Thanks!
