Welcome to SRP. I'm an avid bicyclist myself for an old coot. Mostly singletrack off road but I ride road too. I don't shave my legs but have plenty of scars on my shins from the hazards of the trails. I agree that if you want to use a straight razor for your legs check out the ladies forum. They know a thing or two about that topic. BTW, if you are using a Bic type disposable are you aware that moving the razor back and forth without lifting it off of the skin will help clear the blades and prevent clogging ? I only know this because I am a professional tattooer and learned it shaving customers to prepare them for the tattoo. Good luck with it and the cycling.
