I don't really know what a good bike fit feels like either. I'm a skinny 5/9 ,so I fit on almost any bike. Its not the bike so much that concerns me ,its the saddle. Both hybrids make my crotch sore after 15 miles or so. I don't know whether its the Nike shorts I bought on "sale" , the hybrid saddle ,or just the fact I was never fitted for it. I'm learning as I go along ,and on my new road bike ,I hope to be fitted properly ,and have a better saddle. I think you will just learn as you go along...but the TREK is a good bike. These ladies have a ton of good information.
I'm trying to run again ,but I feel the injury deep in my ankle. Yes, I miss it.
