Hey, kelownagirl, rent a tandem for a day with him and see how you like it. Chris is 2-3 mph faster than I am, so our single bike rides are like yours. We tried a tandem two years ago and loved it. Now we each ride our singles alone during the week, and do big tandem rides on the weekends. We just did our second Seattle to Portland ride on the tandem. It is a ton of fun--wait till you see how fast you can go together--and it smooths out those speed differences that happen on the single bikes.
