Modern lighting technology meets vintage style in Sunlite's Low Rider LED Bullet. The bullet shape hearkens back to the era of generator-powered headlights, but this modern torch features three LED lights to brighten your way through nighttime streets. It runs on two C-cell batteries (sold separately) for hours of use, and the two modes let you choose between a steady beam and a flashing beam. This light mounts easily on your fork or under your headset spacers to shed light on all your night time rides.

- 5 DART plugs for use with the Stan's NoTubes DART tool
$24.99
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

Our Hydration Sport Drink Mix was created for a simple purpose - to replace the electrolytes lost in sweat and to provide a little bit of energy when working out, without offending your palate or gut. We initially created this drink because some of the world’s best athletes needed better. Conventional sports drinks made them sick. They were undrinkable - too sweet, over-flavored, and didn’t even replace what was lost in sweat – which defeated the whole purpose, like fighting thirst with more thirst. The best athletes needed something to safely hydrate, something to quench their thirst, and something to help them perform better. So with their help, we reimagined sports drinks, stripping down what used to be a neon-colored carnival to its bare essentials. In the process, we learned that simple wasn’t just better for elite athletes, it was better for everyone who works hard and sweats. The result is a sports drink with minimal sugar (4g per 100 ml) and a ratio of sugar (glucose + fructose) that is optimized for faster absorption, an electrolyte profile that actually matches what is lost in sweat (800 mg sodium, 80 mg potassium, 100 mg calcium, and 80 mg of magnesium per liter), and only real fruit for flavor for a light and refreshing taste that you can drink all day. That’s it - less sugar, the right electrolyte profile, and real fruit. So, if you’ve never met a sports drink you wanted to take home, your luck is about to change. Drink when thirsty. Don't when not. Repeat as necessary.
