If you ride that 48 pounder you will become very strong when you get on your light cross country rig. My good buddy smoked dudes (almost everyone in the race) who were riding carbon fiber road bikes with egg shaped helmets... he rode a a garbaged picked women's hybrid, I gave him a bent 26 inch front wheel... 2010 Wolfman Triathlon.
Wait till I bring him to the Barn Yard Classic- I will force him to ride another woman's hybrid, but will put sand in the frame.
