In designing an upgraded hubset for our pro-proven Firecrest wheel lineup, we turned to our engineering colleagues at SRAM's development center in Schweinfurt, Germany. The result is the ZR1 hubsets for disc wheels. This hubset features better seal design for improved durability and quicker response with 66 points of engagement. Our engineers spent more than two years developing the ZR1. Proving the durability of the hubset included more than 58,500km of test riding, part of 3,222 hours of total testing. The ZR1 features key technology from Zipp's Cognition hubs. The seal design is the same as the Cognition, with a large dust cap at the base of the driver body and better bearing seals for more protection. The bearing size also is the same as the Cognition, although the Cognition uses a premium bearing. The six pawls are offset to work in two groups of three pawls. There are always three pawls engaging. This design creates a quick engagement feel, with 66 points of engagement. The driver body is designed so pawls stay in place for disassembly to make service convenient. Zipp hubs are designed to use J-bend spokes, the most popular type of spokes today. J-Bend, widely available, are easier to replace. - Better sealing, increasing durability over previous hub model - Quick engagement for a responsive ride - Lightweight - Same bearing size as premium-level Cognition hub - e-bike certified - Disc brake hub with Center Lock rotor interface. The lock ring is included

- Lowest resistance hybrid ceramic (ceramic balls and steel cages) available - Measurable wattage savings between 1.5 and 9 watts per bearing set, depending on the level and condition of your existing bearings - Kits include Freehub body with CeramicSpeed

The Wolf Tooth Resolve Dropper Post is the first dropper post to use a self-bleeding cartridge. It has the shortest stack height of any dropper post on the market, has a short insertion depth, is one of the lightest dropper posts, and is completely serviceable at home. - Self-Bleeding Resolve Cartridge: At the heart of Resolve Dropper Post is a self-bleeding cartridge that removes air from the fluid chamber with every actuation. All dropper posts can get air in the chamber, which leads to sag and squish. Resolve Dropper Post is the only dropper post that purges air from the chamber, which means you'll never need to buy a new cartridge as you do with all other dropper posts. - Shortest Stack Height: The shortest stack height of any dropper post means that Resolve can get your saddle lower than any other dropper post. The lower your saddle, the more room you have to maneuver your bike on drops and techy descents. - Weight and weight per travel is equal to the best: Resolve Dropper Post is one of the most lightweight dropper posts on the market when it comes to grams per millimeter of travel. It's as much as 26% lighter than other dropper posts of the same travel size. - Short Insertion Length: When a dropper post has a short insertion length, longer travel options are unlocked for more bikes. A short insertion length is vital for smaller bikes, frames with curved seat tubes, and frames with seat tubes that have bottle bosses. - Travel Reduction with Spacers: The travel length of your Resolve dropper post can be customized in order to suit your bike and saddle height. Spacer kits are sold separately or those who would like to have the adjustment made later by their local shop mechanic. If you are comfortable with working on suspension components, you may be able to complete the installation yourself.

The Revolution line of rims has been in development since June of 2018. The basis of the whole program was to round out a complete rim offering while implementing all that they learned about The Movement line of rims. It's been said before, and we'll will repeat it, not all carbon rims are made the same way. We Are One developed an entirely new molding process that improves their layup processing and accuracy. The Revolution mold process allows for even more precise fiber placement and extension than their previous designs. Each rim is still hand-made in Kamloops BC! The all-new rim shape allowed them to reduce radial stiffness and utilize less fiber while increasing impact strengths as well. The shape combined with the layup offers a more homogenous system and provides more support to each component of the rim than ever before. UNION RIM There were 3 main goals that went into the design of The Union rim. They wanted a rim that was lighter than The Agent, had lower radial stiffness than anything they'd made before, and gain a dramatic increase in impact resistance. With their new philosophy on layup design and these key points, they were able to achieve something truly impressive. This rim is made for those who want to race Enduro at a high level and ride harder than ever before. If you have ever had doubts about carbon rims, look no further than The Union. PRICE DISPLAYED IS PER RIM TUBLESS VALVES SOLD SEPARATELY NO QUESTIONS LIFETIME WARRANTY So you're thinking of joining The Movement or The Revolution and want to learn a bit about their Lifetime Warranty. Here are the facts, If you break a rim while riding, they send us/you a new one. Period. It's that simple. NO rim replacement cost (shipping will be charged). NO hidden fine-print. Lifetime Support. There is no reason to be concerned about what happens anymore. Ride the industry's best carbon rims and We Are One have your back if you break one! Plain and simple. Please note that due to some people taking "NO questions asked" to the extreme: Their warranty does not cover vehicular incidents, vehicular accidents, or vehicular stupidity. They cover all accidents that occur while riding your bike. **UPDATE Dec.15 2020** If your bike, wheels, or rims are stolen they will not consider that a warranty replacement.....yes someone tried this! We feel that the We Are One warranty is offered for those "oops" riding incidents. If you do, however, manage to make a mistake out there in the big world and it is not while riding, let We Are One know your story, they can be more than fair if the story is good enough to warrant it. If not they will offer a 50% crash replacement and call it fair. Warranty covers original owners only. They do offer second-hand owners a 50% crash replacement.

FACTION RIM Trail bikes with under 140mm of travel are fun weapons of choice. When it comes to wheels pairing a bike with the right tool for the job is paramount. Dressing the bike with too wide of a rim does not fit the bill for these bikes. These trail bikes need a good selection of rubber, but also need to maintain their playful nature, and this is We Are One's answer. Bring on the 27mm internal width of The Faction. A rim that punches well above its weight in overall strength, but rolls as you'd want on a trail bike. Lightweight and surprisingly strong!
