Cassettes & Chains

The Box Four cassette adapts our Prime 9 philosophy of durability, simplicity, and reliability at a great price point. All cogs are stamped from steel, given our durable black coating and then the larger cogs are pinned to each other with spacers for easy installation. - Compatible with HG freehub bodies - Steel stamped cogs - No spiders - Wide ratio and consistent progression - ED black protection

The Box Three E-Bike Cassette offers high gears with more teeth to withstand the rigors of modern E-Bike riding. Adding an extra tooth to each of the three highest gears provides increased durability and decreased wear by distributing the load over a larger area! The Box Three E-bike cassette draws from both of its Box One and Box Two siblings to create a sensible all-rounder. All cogs are stamped from steel and subsequently, the larger ones are pinned to steel spiders. The main difference here versus Box Two is the use of additional weight-reducing holes on the cogs.

New Super Record 12 Speed chain: slim, robust, smooth and precise. The chain, in all its apparent simplicity, plays a critical role in the cyclist's safety and in optimizing the entire transmission mechanism. The new Super Record 12 Speed chain also had to be redesigned from scratch to work with all the other new transmission components. Therefore, the first and most important objective was reducing its overall dimensions. Its width is now 5.15 millimeters, thanks to the new pins which are perfectly aligned with the links’ outer surfaces. The second objective was safeguarding its performance. This was achieved thanks to the Ultra-link system that makes the chain safe and durable, and a special treatment that guarantees extreme smoothness and precision shifting.

For smooth shifting and a quiet drivetrain, pick up Campagnolo's Chorus 11-speed chain. It's unidirectional for unparalleled function and features lightweight hollow pins as well as an anti-friction treatment for shifting perfection. It also boasts excellent wear and flex resistance.

Record chains represent Campagnolo's highest quality and performance chains and are available in 9, 10 and 11 speed versions. - Hollow pins for reduced weight - NI-PTFE antifriction treatment reduces friction for smooth pedaling, reduced noise, greater efficiency and longer chain life - Links (links): 114 - Width: 5.9 mm - Drivetrain Speeds: 10 - Chain Connection Type: Pressed Pin - Half Link Chain: No - Weight: 255 grams

Campagnolo's Record 11-Speed Chain is the right choice for Campagnolo 11-speed drivetrains. This fine chain is engineered for excellent strength, long wear and brilliant shifting thanks to a unidirectional design and an anti-friction treatment that lets it glide across your cassette. It also boasts hollow pins to keep your bicycle as light as possible.

While the greatest focus is generally given to the moving parts of the groupset, the drivetrain is not complete without the cassette. And a Campagnolo groupset is not complete without an extremely efficient, reliable, and high-performance cassette. This is why the Centaur groupset offers high-quality solutions to meet the needs of even the most demanding cyclist. - Built with one steel triplet and 8 steel single sprockets. - Includes lockring - Weight: 291g

- Machined 7075-T6 aluminum singlespeed cogs - Wide base prevents the cog from digging into freehub bodies and reduces flex - Splines are machined for perfect alignment and fit on all mountain cassette hubs

At a full quarter inch wide (6.35mm) at the splines, Kick-Ass-Cogs simply will not damage your free hub body the way a narrower cog can. Made of high strength 7075-T6 alloy (Stronger and harder than most common steels), Kick-Ass-Cogs are precision machined insuring perfect axial and radial alignment that compliments the superior chain lines that cassette style hubs allow. The specially engineered tooth profile on Kick-Ass-Cogs improves both cog and chain life while minimizing drive train friction. With a Kick-Ass-Cog on your bike, you can expect a smooth, quiet drivetrain for miles to come. We do not recommend ACS Crossfire or SRAM PC1 chains as they accelerate the wear on the cog. SRAM PC7X and geared chains have showed no issue. Like all EndlessBikeCo. Products, Color Anodized Kick-Ass-Cogs are made right here in Western North Carolina; not in some faceless factory on the other side of the planet. Please note that not all freehub bodies are created equally (outside diameter that is). Depending on your particular hub choice, you may have to modify your Kick-Ass-Cog however with this modification they will fit on all Shimano style freehub bodies. We like our cogs to fit tight so there is only smooth in your drive train with no damage to that expensive freehub body. Not sure what we mean? email us endlessbikes@gmail.com
