About This Product: Insight Seat Post Extender

Sometimes you just need to cruise around on your race bike and the Insight Seat Post Extender at J&R Bicycles lets you do just that quickly and easily. All you have to do is insert your current seat post into the extender and you are set up in a more comfortable position for warm-ups, cool-downs or just tooling around town. A second seat clamp, sold separately, is required to secure the post to the extender.
