Option C: the best way I've found to get to work faster is to put all the pre-ride preparations onto autopilot. Out of the house & garage and on the road pronto.Same thing in the pm. With the bike... for commuting, it's all in the tires. That the bike has a certain heft is a given. Silly clipless shoes and pedals won't make you faster commuting.
So says me.
