I have three jerseys I really like: Over The Bars Mountain Bike Club, Planet Ultra King of the Mountains series, and North Coast Brewery Acme Ale I picked up on a tour earlier this month. Problem is I hate the zippers on these jerseys. They are the hidden zippers with tiny little teeth. The zipper gets all hung up when unzipping while riding. What I want is a more exposed, larger width, full zipper. Has anyone replaced the zipper on a jersey? Any problems or is this a straight forward thing for a good seamstress?
