Come on, you know your life will be better with this in it! Not only does it perform the wonderous task of transporting your bottle of wine but it is beaitifully designed and looks divine on the bike. Not just for the wino's amogst us, it will cary any bottle with a 3 inch diameter and it has special clamps that keep the bottle in place.
Fit the strap is designed to be snug so that when it stretches, it will be the right size and not too loose. The first couple of times you put a wine bottle in it, it will feel a little snug and the first times you connect and disconnect it from the metal post, it will feel a little snug.
Don't be afraid to rub down the rack with olive oil once a year to keep the leather slightly moist. The material is a vegetable tanned leather that will change colour and feel depending on how often you use it. It will darken with sunlight significantly.
The clamping system is meant to be snug enough to keep the leather from moving around. it's not invisible so don't tighthen the clamp harder than you need to.
