I have a stupid question. Totally new to road bikes. This weekend my husband and I bought some used road bikes. Both are fugis. My bike is really small looking. The frame is a 44cm and the tires are what makes it look so small. There like 650x23c. My husbands bike has noticable bigger wheels. Im not really sure what size they are though. We have always ridden together on our mountain bikes and Ive always been able to keep up with him pretty well. Well hes blowing me away bad now! Could it be because of my small wheels? To me it sounds logical but I know absolutely nothing about bikes. The bike does fit me nice and everything but if hes blowing me away simply because of the wheels I'll be looking for a different bike with bigger wheels. Any thoughts? Please be nice. ( I know I probably need to get into better shape but I hate being blown away)
