The staff at Velo City really know their stuff! If you have a bike in need of repair, take it there, and they will do it quickly and for a reasonable price. They recently converted my husband's racing bike to make it fit me so I could participate in a triathlon, and they did a great job. They are experts at fitting you to the proper bicycle and teaching correct riding form. They are also a great source for other gear, clothing, and even information about riding with groups and local races. I won't go anywhere else in Holland!
