Technology:

Flattop:
In order to offer Deep Range™ technology, SRAM had to develop a narrower chain. The unique articulation of the Flattop technology not only made this narrower chain possible, but also resulted in quieter operation, increased strength and durability.

DESCRIPTION:

Our Dual Action Repair for Tubeless (DART) system offers a better way to fix damaged tubeless tires. Specially treated DARTs don’t just plug large slices and punctures in your tires, they react with Stan’s sealant to form a permanent airtight bond. This Refill kit contains five DARTs and a carrier that makes reloading your DART Tool fast and easy, all stored in a compact, sealed container.

In designing the DART, we took a long look at existing plug technology and found many ways to make major improvements. Unlike large, sharp insertion tools and rubber plugs that can damage rim tape and force punctures to open even wider, DARTs are safer, easier to use and much more effective at sealing your damaged tubeless tire.

Each DART includes a reinforced, sonically welded 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. Continuous improvement has led to a shape and material that resists fraying and ripping to seal even difficult punctures. By being 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.
