Which Enduro Fork Is Better? – New FOX 38 Factory vs. New RockShox ZEB Ultimate 2027

The recent relaunches of the FOX 38 Factory GRIP X2 and the RockShox ZEB Ultimate have reignited debate over which enduro fork offers superior performance. Both models, originally launched in 2020 to bridge the gap between traditional single-crown and dual-crown forks, have undergone comprehensive redesigns for 2027. These updates have prompted a direct comparison, with extensive testing conducted across varied terrains including Queenstown, Finale Ligure, and the Palatinate Forest to evaluate their capabilities in real-world conditions. The FOX 38 Factory GRIP X2 weighs in at 2,412 grams and retains much of its previous design, featuring a revised GRIP X2 damper with full external adjustments for both low- and high-speed compression and rebound. Its new NA3 GlideCore air spring aims to reduce internal friction, while a floating axle system minimises stiction between the stanchions and lowers. Additional refinements include an improved fender system that bolts directly onto the fork and repositioned pressure relief valves, enhancing both functionality and user convenience. In contrast, the RockShox ZEB Ultimate is slightly heavier at 2,540 grams and adopts a more angular, aggressive aesthetic. It incorporates the updated Charger 3.2 damper, which allows external adjustment of compression and low-speed rebound but lacks separate high-speed rebound tuning. The standout innovation is the LinearXL air spring combined with the new AirAnnex system, which provides adjustable end-stroke progression through the ABO (Adjustable Hydraulic Out) feature. Pressure relief valves have also been relocated to the crown, reflecting SRAM’s evolving design language. Testing involved side-by-side comparisons by experienced riders on identical trails, with setups carefully matched to ensure fairness. The diverse terrain included technical switchbacks, high-speed sections, jumps, and braking zones, designed to push both forks to their limits. While telemetry data was collected for further analysis, initial impressions focused on the forks’ trail performance, highlighting subtle differences in damping behaviour and ride feel that will be explored in greater depth in future reports. The renewed competition between these two flagship enduro forks underscores the ongoing innovation in suspension technology, with each model offering distinct advantages depending on rider preference and terrain demands. Riders seeking fine-tuned adjustability and reduced friction may lean towards the FOX 38 Factory, while those prioritising end-stroke control and a robust damper might prefer the RockShox ZEB Ultimate. Further detailed analysis and rider feedback will be essential in determining which fork ultimately sets the benchmark for the 2027 season.
