- 5 DART plugs for use with the Stan's NoTubes DART tool

Stan's Dual Action Repair for Tubeless (DART) fixes damaged tires faster, easier, and better than existing plug tools. While traditional tire plugs try to wedge rubber strips into a puncture, the DART creates a chemical reaction with your Stan's sealant to quickly form a permanent airtight bond. The DART's plastic tip is barbed to anchor firmly in place and stay put during even the most aggressive riding while being safer for rims, rim tape, and your hands. The material of the DART is also more flexible, and its laser-cut shape is optimized to contour to the shape of different punctures, maximizing surface area to increase the sealing reaction. Because the DART anchors to your tire and creates an instant bond with your sealant, it also won't pull out while riding the way a conventional plug can. One of the best features of the DART's design is that it doesn't require trimming once inserted, and excess material won't get in the way of your ride. DARTs can't be felt while riding, even on road tires, and they wear smooth naturally. - Repairs large punctures and slices - Reacts with Stan's sealant to form an instant, airtight seal - Barbed plastic tip anchors into tire and will not pull out when riding - Flexible material and laser-cut shape conforms to puncture and bonds with sealant - Wears off clean, no trimming needed, and can not be felt while riding, even on road tires - Lightweight, compact tool fits the shape of your hand for more precise use and includes built-in valve core remover - Includes two pre-loaded DARTs for sealing multiple and larger punctures - Clear caps keep DARTs clean and unthread quickly for fast deployment - Simple and easy to refill

The Chain Gang includes: - CM-5.3 Cyclone Chain Scrubber - GSC-1 GearClean Brush - 8 oz. bottle of Bio ChainBrite The CG-2.4 works on nearly any bike, including multi-speed, single-speed, and e-bikes.

Cleans bicycle chain quickly, easily, and effectively — without the hassle and mess of removing the chain from the bike. The Cyclone uses a large solvent reservoir, hundreds of rotating bristles, and a two-step cleaning process to get chains really clean, improve shifting performance, and extend the life of the chain and other expensive drivetrain parts. - Works with all multi-speed bikes (5, 6, 7, 8, 9, 10, 11, and 12-speed) as well as some single-speed models and e-bikes - Strong magnet at the bottom of the fluid reservoir holds metallic particles scrubbed from the chain - Special wicking sponge draws solvent from the chain as it exits, minimizing drips and mess - Sturdy handle makes the Cyclone easy to use and control - Holds 2 fluid ounces (59ml) of solvent

To prevent poor shifting and uneven drivetrain wear, most manufacturers recommend chain replacement at or before 1% stretch. Now you can quickly and accurately determine the wear and stretch of any chain with Park's Chain Checker. Simply insert the Chain Checker’s pins into 2 links, press the swingarm gauge tight, and then check the gauge window for an accurate reading!

A worn chain shifts poorly and wears sprockets at an accelerated rate. Park Tool's Chain-Wear Indicator is a “go-no go” gauge designed to accurately indicate when a chain reaches .5% and .75%, the points at which most chain manufacturers suggest replacement. The updated CC-3.2 is longer, more accurate and features permanent measurement markings.
