Our Sport Superfuel Drink Mix was created for athletes who push so hard that they can't easily take in enough calories to perform at their best. For years, we've preached fueling with real food, like our famous rice cakes or Anytime Energy Bars. Why? Because traditional fueling gels and drinks use carbohydrates that break down too fast to tolerate, causing gastrointestinal distress. But, we get it—you can't always make or carry real food—you want power in a bottle. We've discovered the answer in a better carbohydrate (with a funny name) that digests steadily like real food does: Cluster Dextrin. One serving of Superfuel gives you 400 calories, powered by Cluster Dextrin, plus the electrolytes lost in sweat to fuel and hydrate your biggest days. We've tested this product for over 20 months with the world's greatest athletes, including Gold Medalist Triathlete Gwen Jorgensen and the EF Education First Pro Cycling team. It has allowed these athletes to drink their fuel on some of the longest and most intense events in the world when they can't eat real food without causing gastrointestinal distress. Use it when there's no time to chew. NON-GMO, GLUTEN FREE, DAIRY FREE, KOSHER, VEGAN

The Iconic SILCA 24.1 gasket is the heart of the press-on Presta chuck. The current 242 gasket utilizes a high tech and very red, fully synthetic elastomer base material.

Few tools are used as frequently and can cause as much heartache or wasted time as the seemingly simple Hex and Torx keys. It's one of the first things you notice at the top levels of motorsport tools, or in the toolboxes of Pro-Tour mechanics: extremely high-quality tools. The reasoning is simple, better tool fit leads to better feel and confidence for the mechanic as well as a significant reduction in the likelihood of damaging exotic fasteners made from titanium or aluminum. - High-strength S2 steel tools - Precise tool interface dimensions - Polymer coating for superior grip - Laser-etched size indication - Compact tool holder - Hex Wrenches: 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10mm - Torx Wrenches: T7, T8, T9, T10, T15, T20, T25, T27, T30 - PLEASE NOTE: The T7 tool features a 100-degree bend rather than a 90-degree for improved control and access to very small fasteners

All the benefits of a highly secure titanium bottle cage with a black finish that won't wear away. Other secure cages don't allow easy access to bottles, scratch your bottles, etc, but not SICURO. • 30g • Black Cerakote coating • Will not chip, break, or fade • Easy in-and-out • 3-2.5 titanium tubing • Hand bent in indianapolis • Laser welded • Extremely secure design

Each SICURO Ti cage is hand-made in the USA at our Indianapolis, IN headquarters using custom manufacturing processes and a state-of-the-art laser welder, the first of its kind in the bicycle industry. Made from aerospace-grade titanium tubing, these cages feature unique slotted mounting eyelets that allow fore/aft adjustability on the bike. The second-generation Ti Bottle Cage has a base-plate change to add more flexibility to the positioning on the frame, allowing usage for smaller frames. In our quest to create the ultimate bottle cage, we found ourselves completely fascinated by the look, feel, and durability of tubular titanium construction. This combination of design characteristics produces a cage that has better retention on gravel and other harsh surfaces and has proven to be the superior design when mounted on the underside of the down tube, so common in adventure riding and touring. While classic in appearance, this material, and its manufacturing is as complex and high-tech as it gets. - Seamless 3-2.5 titanium tubing - Extended adjustment mounting: up to 21mm fore/aft - Weight: 30 grams - SILCA Shield Warranty included covering your cage for 25 years! - Please note: bolts are not included

Never lose a bottle again with this incredible titanium bottle cage. This lightweight design doesn't mark your bottles, allows easy access, and holds your bottles on the worst terrain. • Seamless 3-2.5 titanium tubing • 30 g • 21mm fore/aft adjustment • Hand bent in Indianapolis • Easy in-and-out • Extremely secure design • Laser welded • Optimized for purist bottles

We set out to create the most stable, low profile mounted, feature loaded, waterproof seat bag available. The Spinelock seat bag checks all the boxes. The Spinelock integrates user tested and approved features like a one-way air purge valve, rear light slots, loop and bungee deck, and an external plastic bottom with a new patented attachment system. Stability was the driving element in the design process. If you want something you can pack and forget, the Spinelock is your seat bag. There are two size options, neither of which sacrifice features for capacity. The smaller but largely versatile Spinelock 10L maximizes your carry with minimal tire clearance and provides a generous amount of waterproof storage with additional space on the external corded deck. . If you are going on a long expedition or carrying cold weather gear we recommend checking out the Spinelock 16L. How it works: - The Spinelock stability system consists of three components: the saddle clamp, seat bag mounted "Spine" baseplate, and pin. - A low profile, high strength, forged aluminum clamp works in combination with precision IGUS bushings to form the pin interface. Twin forged upper arms, fastened by Torx-25 bolts, rotate into position above the saddle rails for easy mounting. - Resembling a spine ramp familiar to skateboarders, the "Spine" baseplate is made of an impact resistant UV-stabilized nylon and is integrated to the seat bag surface. The plate features two mounting positions to accommodate seatpost setback and saddle adjustments. To connect the bag, you simply line up your selected mounting position to the seat mounted clamp and slide the pin through the aligned holes. Attaching the side compression straps to the wings of the clamp fixes the pin in place and you're ready to ride!

The Bottom Bracket Wrench removes and installs Shimano Hollowtech II, Race Face X-type, FSA MegaExo, Campagnolo Ultra-Torque and TruVativ Giga X-pipe bottom brackets. Laser cut for a precise fit, one end of the BBT-9 securely engages the 16 cup notches, while the other end engages the 8 internal splines of the crankarm adjustment cap.

The CC-4 is a drop-in style gauge that measures bicycle chain wear. The laser cut CC-4 accurately measures a long section of chain and strategically comes in contact with the chain in three places, quickly and easily taking the guesswork out of knowing when chain replacement is necessary. A worn chain will cause poor shifting as well as accelerate drivetrain wear. The tool works on any 5 to 12-speed derailleur chain (including SRAM AXS) and is designed to accurately indicate when a chain reaches .5% and .75% wear, the points at which most chain manufacturers suggest replacement.

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
