Whether you own a Fox or Rockshox fork of rear shock, Syncros doesn't discriminate because it works with both. Beyond that, it functions better than the stock pump supplied with your shock due to better design and build quality.
At first glance, it appears simple enough, but when you use it, its full potential is revealed. The flexible rubber hose extension unfurls from the main shaft to provide easy attachment to the valve. The telescoping shaft inserts copious amounts of air into any chamber. The easy to read pressure dials on the pump range in size from one to three inches, so you can actually gauge how much pressure and air you are inserting. The solid alloy construction with heavy duty seals provides accuracy and durability. Simply put, feature per feature and overall quality are simply unmatched by any competitor. Chapeau Syncros.
