Our intention with Reverb AXS™ was inventive and pure: No hoses. No routing. No energy wasted. Not a single thing in the way of the experience. We created a reliable wireless-electronic dropper post and controller that actuates with drastically less effort and zero distraction. Expanding what’s possible on a bike, Reverb AXS™ is enabled by SRAM AXS™ technology, a new level of interaction, personalization, and connectivity across all AXS™ enabled components.Cutting out the cables makes set up fast and easy. No external hoses. No internal routing. No energy wasted. The Reverb AXS™ complete wireless design is fast to install, and easy to pair. Complimented with an all-new post head, the turn of a single rail-retention bolt makes for a quick and effortless saddle install. Make it perfect with one additional bolt at the front of the head for tilt-adjust and position lock. Drop it in, and send it down.Tucked neatly into the back of its post head, the Reverb AXS™ uses the same rechargeable SRAM battery found on the Eagle AXS™ derailleur. Easy to remove, and simple to interchange between components if needed. From sun up to sun down, the SRAM battery boosts plenty of ride time (40 hours on trail depending on use) and fully recharges in under an hour. Using an auto-wake sensor, there’s no need to turn it on/off, it’s ready when you are.SRAM AXS™ technology is opening a new door to a connected experience with your bike.

As with the mechanical parts, the rear derailleur represents the pride and joy of the EPS project and encompasses a series of technologies and innovations that allow shifting speed to be optimised and guarantee unprecedented precision, even in the case of multiple shifting with 11 sprockets at a timeThe EPS rear derailleur is comprised mainly of a mechanical structure, derived from the mechanical gear and composed of a derailleur rod/parallelogram/derailleur cage, of a worm screw enabled by an electronic actuator. As with the derailleur, the electronic rear derailleur actuator is composed of a gear motor and a sensor, the built-in resolver, that reads its movementsThe geometry of the parallelogram has been made more rigid and optimised to promote interaction with the electronic partsThe lower and upper bodies, the parallelogram and the carbon derailleur cage are moved by a screw system and lead worm screw (not a spring screw) which, in turn, is enabled by the electronic actuator that communicates with the DTI. The built-in resolver inside the actuator is capable of reading the movements of the rear derailleur at any time and optimising its position by communicating with the DTI (Digital Tech Intelligence)The rear derailleur is also equipped with a play recovery system using a helicoidal spring that optimises stability and precision and keeps operation and performance constant over time, even after many kms have been coveredAs with the mechanical rear derailleur, it is possible to optimise its position with respect to the frame and chain by acting on two adjusting screws: the screw that adjusts the mechanical end stop and the screw that adjusts the distance between the upper pulley and sprockets. By using these screws it is possible to optimise the installation of the rear derailleur and increase the precision of its operationDTI: Digital Tech Intelligence is housed inside the Power Unit and it continuously monitors the signals that arrive from all the EPS components, thus managing their operationMULTI-SHIFTING: There are no longer any limits to Multi-shifting and the choice is at the fingertips of the cyclistRIDE BACK HOME: The uncoupling mechanism of the rear derailleur is useful if the battery runs out on the road, allowing you to manually uncouple the rear derailleur to position it on which ever sprocket you requireWATER PROOF: In order to achieve the IP67 classification, all the electronic components of the EPS system underwent a series of tests, which proved their ability to function perfectly under one meter of water for at least 30 minutes

Additional low-speed compression (Open mode adjust) 22 clicks, Low-speed rebound 10 clicks. Lower Leg Bypass Channels: As a fork compresses, the air volume within the lower legs decreases, increasing air pressure. The more the fork compresses, the more pressure increases. This effect can have the unintended consequence of preventing full travel from being achieved. Fox Suspension's lower leg channels help alleviate this issue by dramatically increasing air volume within the lower legs and thereby reducing the amount of additional unintended pressure ramping. Another benefit of these channels is that lower leg bath oil is circulated to the upper reaches of the lower legs, continuously lubricating the foam rings and bushings as the fork compresses and extends through its travel. Lower Leg Arch: Stiffness-to-weight is the ultimate metric for bicycle design. Engineers invest countless hours poring over every ounce of material in an effort to optimize this critical ratio. The all-new 34 pulls out all the stops, shaving every possible gram while making sure not to compromise the stiffness or strength requirements of modern trail riding. Modern frame designs and geometry trends require modern suspension design solutions. The arch design is designed to pair perfectly with modern trail bikes. Head tube profiles have grown larger and larger, and fork offsets shorter and shorter. Fox Suspension's new arch shape takes this need into account by jutting forward to provide ample headtube clearance at full compression. State-of-the-art computer modeling techniques helped us to create an organic lower leg shape that optimizes stiffness with the absolute minimal amount of material.Manufacturer's Part Numbers: 910-21-059 Black 29" 100mm 44mm 910-21-058 Black 29" 100mm 51mm 910-21-061 Orange 29" 100mm 44mm 910-21-044 Black 29" 120mm 51mm 910-21-043 Black 29" 120mm 44mm 910-21-042 Orange 29" 120mm 44mmBuy Fox Suspension Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Fox Suspension 36 Float Factory E-Optimized Grip 2 ForkPart of Fox Suspension's prestigious Factory Series, this electric mountain bike (E-MTB) suspension fork comes trail-ready with technologies that are designed to exceed the demands of Factory-level riders. With an eye-catching genuine Kashima coating on its upper tubes, it provides slippery smooth operation while remaining ultra-durable as you tackle challenging terrain conditions. Benefitting from a lightweight Float EVOL air spring and a highly adjustable GRIP2 damper, the 36 offers an excellent combination of performance and tunability, everywhere from backcountry routes to the EWS circuit. No stranger to winning awards, accolades and Enduro World Series (EWS) races, this E-MTB specific model is engineered for powerful front-end suspension performance. E-MTB Fork with GRIP2 DamperFox Suspension's GRIP2 damper is the benchmark for unparalleled ride quality and ultra-precise adjustability. GRIP2 includes patented Variable Valve Control (VVC) technology which allows for external fine-tuning of suspension performance. GRIP2 achieves with the twist of a knob what typically requires the time-consuming and complicated task of completely disassembling and reassembling the fork.Float EVOL Air SpringEVOL technology increases negative air spring volume, optimising small bump sensitivity. EVOL's linear spring curve delivers plushness off the top, extra mid-stroke support, and more tuneable bottom-out progression. The benefits of EVOL are further enhanced by the Lower Leg channels and Bleeders, which both function to reduce air pressure captured in the lower legs, allowing the EVOL air spring to operate freely without unintended interference.Features: Upper Tube Finish: Genuine Kashima Coat Use: Electric Mountain Bike (E-MTB) Axle: 15QRx110mm Boost Air Spring: Float EVOL Damper: GRIP2 with dual Variable Valve Control (VVC) on High Speed Compression (HSC) and High Speed Rebound (HSR) circuits Steerer Diameter: 1.5" tapered Rotor Compatibility: 180mm direct Post Mount, Up to 230mm compatible Increased crown diameter to match modern frame shape profilesTechnologies: Factory Series: “Factory” says it all - feature-packed and designed to exceed the demands of Factory-level riders. What we sell is what they race. Factory Series products feature slippery smooth, ultra-durable Genuine Kashima Coat. Adjustments: High-speed compression (with VVC) 8 clicks. Low-speed compression 16 clicks. High-speed rebound (with VVC) 8 clicks. Low-speed rebound 16 clicks. Floating Axle: Floating axles might look similar to other axles, but in fact they offer a distinct performance advantage due to their unique ability to match the exact width of the fork's wheel mounting surface precisely to the front hub flange spacing, thus creating perfect chassis alignment and eliminating unwanted friction between the upper and lower fork legs. Floating axles provide much smoother suspension movement throughout the entire range of the fork's travel, notably improving sensitivity and overall ride quality. The all-new 36 and 38 come equipped with a new quick-release lever-operated patent-pending floating axle system, combining the benefit of a floating axle with the ease of a tool-free quick-release. With this system, spacing is locked in via a floating sleeve, allowing repeated front wheel removal and reinstallation while maintaining perfect fork alignment. Floating sleeve positioning comes preset from the factory so if you are unsure of how to operate the floating axle system or simply don't want to bother with it, you can just install the front wheel and get on with your ride. Lower Leg Bypass Channels: As a fork compresses, the air volume within the lower legs decreases, increasing air pressure. The more the fork compresses, the more pressure increases. This effect can have the unintended consequence of preventing full travel from being achieved. Fox Suspension's lower leg channels help alleviate this issue by dramatically increasing air volume within the lower legs and thereby reducing the amount of additional unintended pressure ramping. Another benefit of these channels is that lower leg bath oil is circulated to the upper reaches of the lower legs, continuously lubricating the foam rings and bushings as the fork compresses and extends through its travel. Bleeders: Fox Suspension's lower leg bleeders allow for atmospheric pressure equalization at the simple press of a button. Pressure build-up in the lower legs dramatically decreases fork performance, preventing full travel from being achieved, and diminishing small bump sensitivity and responsiveness. Lower Leg Arch: Stiffness-to-weight is the ultimate metric for bicycle design. Engineers invest countless hours poring over every ounce of material in an effort to optimize this critical ratio. Fox Suspension's all-new lower leg design pulls out all the stops, shaving every possible gram while making sure not to compromise the stiffness or strength requirements of modern enduro and gravity style riding. Modern frame designs and geometry trends require modern suspension design solutions. The arch design of the all-new 36, 38, and 40 is designed to pair perfectly with modern Enduro and Downhill bikes. Head tube profiles have grown larger and larger, and fork offsets shorter and shorter.
