So much of this hobby comes down to so many factors. The placebo effect. That top of the line racing bike decked out in perfect top of the line components that everyone says is the best bike to ride, will probably ride the best because your mind says so. The one you are most proud to own. It could be the prettiest bike or color of the bike. Fit, good wheels and tires matter the most. For me it comes down to what bike makes me feel good to ride. All of my bikes have great tires and wheels. All fit and ride great. One just feels so special to me that its like floating on clouds. Strava tells me they are all the same.
