About sex life. Upgrades do make you look sexier. Ladies in our club normally dont chat with a guy unless he has a ultra light carbon bike ideally an aero one with all the latest goodies. Girls love to touch aero bikes. Embarassing tho if an aero macho cant keep up with a 65 year old bloke on a 20 year old alloy bike. Seen it before. So if you upgrade then bring the matching skills with it. Otherwise, NO getting laid and money wasted !!
