Today as I was about 2 miles from home on my Dawes Horizon on a 17 mile ride a friend caught up and spoke in my ear. My pace is usually a slowish 12 mph. I of course felt the need to match his pace and as I was only 2 miles from home thought I would be ok. Well I found the pace of the racing bike somewhat different and although completed my ride I did found it difficult. Could I expect to increase my mph by using a racing bike? If so what could I expect from a simple change of bike.
