Each DART includes a barbed plastic tip that anchors into a puncture securely while being safe for rims, rim tape and hands. Attached to each barbed tip is a specially shaped, laser-cut material treated with a patent pending solution that reacts with latex sealant. The DART’s ability to create a chemical reaction with sealant is its most impressive feature, but the material itself is also important. By being lighter and more flexible than traditional tire plugs, the material of the DART can better contour to the shape of a slice or puncture. This special material is also much lighter than conventional tire plugs and can’t be felt when riding, even on a road tire. That means a DART does not need to be trimmed after being inserted, unlike other plugs that can accidentally be pulled out in the process of riding if not trimmed. With the DART, repair is as easy as locating the puncture, inserting DART, and getting on with your ride.
