How do I replace road bike hoods? I commute daily on a road bike with Shimano Tiagra STI shifter/brake levers. The rubber hoods are pretty grimy and getting sticky, torn up and unpleasant these days. Repair and replacement of pretty much everything on my bike seems very straight-forward, but I can't figure out if these parts can even be replaced, much less how to do it. Ideas?
Easiest thing to do is just cut off the old hood then take the new hood and thread it on over the bottom of the brake lever. Some are 'ergo' and have a right and left hood so make sure that you watch for right and left hoods.
