Unior Nipple Assembly Tool

Anyone who's ever built bicycle wheels knows the aggravation associated with dropping a nipple inside a double walled rim, initiating the need to rain dance around the shop with your half wheel, spokes flailing, hoping the nipple emerges. Prevent nip slips and save time and hassle, too, with the Unior Nipple Assembly Tool. The spring loaded tip locks the nipple onto a small spindle that can then be safely inserted into the spoke hole in the rim bed, not release until you want it to, making wheel building far less frustrating and making you more productive.
