If you ride your bike for long periods of time, you want to have some kind of soft protection on the handlebars so that you don't chafe your hands. One option is installing a set of foam handlebar grips. These are very tight fitting, so they can be a bit frustrating to install. With the right lubricant and a little bit of patience, though, you'll have the foam grips installed on your handlebars in no time.
Fill the spray bottle with water, then put some of the liquid dishwashing soap in the bottle, so that when you spray the bottle, the mist has a slippery quality.
Apply liquid dishwashing soap to the inside of the foam grips. Spray the dishwashing soap and water mixture onto the handlebars liberally.
Push the foam grips from the end of the handlebars and up onto the handlebars until they can't go any farther.
Fill the syringe with the rubbing alcohol. If the foam grips get stuck while pushing them up the handlebars, insert the syringe into the foam grips. Inject the rubbing alcohol into the area between the grip and the handlebar to lubricate the grip. Allow the grips to dry for at least 24 hours before riding the bicycle.
