Wouldn't it be easier and cheaper to run up some stairs, or just run really fast?
It would be much easier to just do sprint runs, yes. I do get nasty shin splints just from jogging, so I thought I would combine replacing the old broken bike with a new one for commuting and be able to do the sprint training with a bike as well. I had not condisdered the point you made about the durability of the components when used primarely for this type of riding. Do you think this applies to all entry level bikes or primarily the skinny tires of a road bike?
