It`s worth to pay more attention to a picture sometime. At a first glance I thought – two blonds with nice tits working on a motorcycle – what a good picture for the Bike Porn post. But looking at those … wheels with more attention I saw a smart trick who to protect those chromed nuts and bolts from getting “bruised” by the wrench. Use a Celofan or PVC bag to cover the nut or bolt then use the wrench as you would normally. Just pay more attention to the picture.
