All Box stems are engineered and crafted using our Oversized Technology. As we follow the load paths down the handlebars we have focused our attention on the stem-to-bar interface. Since the Oversized handlebars have an increased wall thickness and tube diameter in this sector we have reciprocated with an augmented stem interface with greater surface area. We’ve done this by moving material from low stress areas. This has greatly minimized twist and contributed to responsiveness. As the stem in mated with the handlebars we have contributed to increased pedaling stiffness by providing a backstop to the “lifting” phenomenon. There is no point pushing hard on your pedals if you can’t pull up on your handlebars and deliver that power. Power can easily be lost to handlebar-to-stem deflection and the consequences can be poor power delivery and steering control. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency. Key differences: This particular model stem pushes our Oversized Technology to the extreme as it maximizes the shift of material from low stress zones to the Oversized interface. These stems are engineered for the smaller-sized racers. -Lightweight 3D Hollow Design -Front-Load Clamp Design to Fight Pull-Up Forces -Large Bar Bore -Large Hollow Clamping Bolts -Superior Strength

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. FEATURES - Our Best All-Rounder Cassette - Steel Stamped Cogs - Steel Stamped Spiders - Ultra-Wide Ratio with Consistent Progression COMPATIBILITY - Box One Prime 9 Chain 126L DLC Black - Box Two Prime 9 126 Link Chain Nickel - Box Three Prime 9 126 Link Chain Polished - Box One Prime 9 Rear Derailleur - Box Two Prime 9 X-Wide Rear Derailleur Black - Box Three Prime 9 X-Wide Rear Derailleur Black - Box One Prime 9 Single Shifter Black - Box Two Prime 9 Single Shifter Black - Box Three Prime 9 Single Shifter Black

Hollow stems are cold forged from the highest quality 6061-T6 aluminum available. Featuring an open skeletal design and a dual mid-bolt wedge mounting system, they are lightweight yet maintain a very high level of strength. A 53mm extension stem weighs just 218 grams/7.7 ounces. By removing the rear pinch bolts and moving the mounting bolts to the middle of the stem, we reduced the weight and size and eliminated a serious hazard to the rider’s knees. These stems come with either a 48- or 53mm extension and a 22.2mm bar bore. To ensure proper clamping force, the stem must be mounted on a fork with at least 45mm of exposed steerer tube. Not compatible with forks that have carbon fiber steerer tubes.

All Box handlebars are engineered and crafted using our Oversized Technology. Handlebars have a dual purpose as they contribute to both steering and pedaling stiffness. By strategically varying wall thicknesses and tube diameters, we have moved material from 3 low-stress areas to zones of high load. This has greatly minimized twists and contributed to responsiveness. Concurrently we have increased pedaling stiffness by providing a backstop to the “lifting” phenomenon. There is no point pushing hard on your pedals if you can’t pull up on your handlebars and deliver that power. Power can easily be lost to handlebar deflection and the consequences can lead to poor power delivery and steering control. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency. Key differences: This particular model handlebar is tailored for larger-sized racers and also takes our application of Oversized Technology one step further as it employs a tougher chromium molybdenum steel. This allows for a greater variation of wall thicknesses to combat the higher loads coming from that extra rider weight. FEATURES - Oversized™ Technology - Chromoly Steel - Toughest Handlebar Material In • Lineup - Massive Clamp Interface for Steering Stiffness - 13 Butted - Variable Wall Thickness to Reduce Weight

Triggy Alpha - The name speaks for itself - the new pack leader of dropper remotes. Since the beginning our Triggy has proven to be a favourite among many many pro riders and testers but with Triggy Alpha we have now set the bar even higher and we confidently say: There is no better remote on the market. The video is pretty much explaining very well what makes Triggy Alpha stand out amongst others: - Ball bearing on the paddle - Angle-adjustable paddle - Black anodized aluminum body and paddle with laser engraved finish - 2 available paddle lengths for crisp or soft dropper engagement - 2 mounting holes - Integrated cable tensioner - Direct mount for almost any brake available (see mounting options) - New cable clamping for universal dropper compatibility - Extremely low weight: 32g/34g (short/long) - Maximum cable pull: 11 mm The short version mimics our proven original Triggy paddle geometry. The long variant features a 7mm longer paddle and reduces the required forces by about 15%. Triggy Alpha is compatible with any commonly available aftermarket cable-actuated dropper post on the market. 1 set Triggy Alpha includes: - 1x Triggy Alpha remote (short or long) - 1x shift cable - 1x wire endcap - 1x BikeYoke Splits Clamp or I-Spec Adapter (optional)

Choose our 2X remote for your dropper if you don't have enough space for a Triggy under your left side handle bar, for example if you are still running 2-by or 3-by shifting with front derailleur or if you have anoter remote for suspension or e-support. It also features a hinged clamp, that allows snapping your remote onto your handlebars without having to take off grips or brake levers. The clamp is made from a high-tech plastic compound and aluminium. The paddle itself is made from 6061-T6 aluminum, black anodized and finished with a dark anodized BikeYoke logo. Allowing a maximum of 10mm cable pull our 2X is compatible with any known dropper post on the market. The cable/wire is clamped via screw on the lever itself.

Many dropper posts feature remotes, that do not live up to a standard, that you would expect, when paying a lot of money for a dropper post. Even the most expensive droppers out there often come with remotes, that have ridiculous play, are made from plastic, bulky, heavy, or just do not function as they could. We put a lot of time and testing into the design of a remote lever that fulfils everything we want to see in a remote for dropper posts and since its introduction it has proven to be a favourite of many pro-riders and testers. Features: - Super lightweight (24g without clamp) - Made from 6061-T6 aluminium with a CNC finish, black anodized and laser engraved - You can (but don´t have to) bolt it directly to the most common brakes without an extra clamp - Exceptional finish and touch - Individual mounting points to adjust position - Integrated cable tensioner - 12.5 mm of maximum cable pull 1 set Triggy includes: - Remote lever unit (black anodized and laser engraved aluminum body and lever with cable tension adjuster) - Shift cable - Shift cable endcap - 1x "Splits" clamp or I-Spec adapter (optional)
