RockShox Reverb AXS XPLR Seatpost - 75mm400mm

The RockShox Reverb AXS XPLR Seatpost is a wireless dropper post built to give gravel riders more control, comfort, and confidence on rough terrain. Its 27.2 mm chassis with ActiveRide air-only internals delivers built-in compliance for smoother rides while staying fully rigid at full height, and wireless AXS control drops the saddle instantly when terrain becomes technical.Key Features and Benefits:ActiveRide air-only internals: The air-only design creates a compliant micro-suspension effect that absorbs repeated gravel impacts and trail chatter. This reduces fatigue and improves stability, helping you maintain speed and control on rough surfaces.Fully rigid top-out design: The post remains firm when fully extended to preserve pedalling efficiency and power transfer. This keeps your riding position stable and efficient during long climbs and fast road sections.Wireless AXS actuation: Electronic control removes cables and hoses for simple setup and clean cockpit integration. This ensures consistent performance and easy installation across gravel and mixed-terrain bikes.Instant saddle drop: The saddle lowers at the press of a controller to increase body movement on descents and technical terrain. This improves bike handling and control on loose surfaces and steep sections.Two travel options (50mm or 75mm): Riders can choose the drop that suits their riding style and frame geometry. This provides a personalised fit that improves comfort and control on varied terrain.AXS mobile app customisation: Settings can be tuned and monitored through the AXS app. This allows riders to customise button functions and manage components for a tailored riding setup.Compatible with drop-bar and flat-bar AXS controllers: Broad controller compatibility supports gravel, adventure, and mixed-terrain bikes. This creates flexible cockpit setups without changing ecosystems.Compatible with oval carbon saddle rails: Support for 7×9 and 7×10 rails increases saddle choice. This ensures compatibility with modern performance saddles for improved comfort and fit.Shared SRAM AXS battery platform: The seatpost uses the same battery as other AXS components. This simplifies charging and provides easy battery swapping during long rides or events.IPX7 waterproof rating: Sealed electronics resist water and harsh conditions. This ensures reliable performance in wet weather and demanding gravel environments.Riders benefit from greater control and reduced fatigue across mixed terrain and long gravel routes. ActiveRide compliance smooths repeated impacts while wireless dropper function increases confidence on descents and technical sections. The clean wireless setup and AXS ecosystem compatibility create a modern cockpit that is easy to maintain and customise.Upgrade your gravel bike with a dropper post designed for comfort, control, and simple wireless integration, and complete a cockpit ready for demanding terrain.Please Note; Reverb controller NOT included. Please click here to purchase the controller.Features:New 27.2mm Reverb AXS XPLR for increased control and confidence on gravelActiveRide air-only internals provide a rigid top-out with built-in compliance for comfort and stabilityAvailable in 50mm or 75mm travelCompatible with 7×10 oval carbon saddle rails400mm length, or 350mm length for 50mm dropAXS technology allows full rider customisation via the AXS Mobile AppCompatible with AXS drop-bar or flat-bar controllersShares battery format with all SRAM AXS componentsWaterproof to IPX7SRAM AXS battery and charger includedSpecifications:Post Diameter: 27.2mmTravel: 50mm / 75mmRemote: AXS controller sold separatelySaddle Rail Compatibility: Round / Oval (7×9)E-Bike Approved: YesPower Source: AXS battery
