E-Storia Coil Shock

The EXT E-Storia Coil Shock is a heavy-duty e-MTB-dedicated rear shock built for enduro riding where higher bike weight and motor torque demand more damping control and a wider tuning window. Its coil-spring feel prioritizes traction and composure on long, rough descents, while integrated pedaling support features help manage efficiency on climbs and transitions.

Key engineering that matters on e-MTB enduro builds

1. e-MTB-optimized 4-way damping adjustment - Independent tuning of LSC, HSC, and LSR, plus LOK, to better control chassis motion under the added mass and load cycles typical of e-bikes
2. LOK 2.0 two-way lockout with blow-off - Adds on-demand pedaling support across mixed surfaces while a blow-off valve helps prevent harshness if the lever is left engaged when the trail drops
3. HBC bottom-out circuit - Increases damping force in the last 20% of stroke to resist hard impacts, enabling lower spring-rate setups for improved small-bump compliance, traction, and control
4. Integrated reservoir head with large-volume bladder - Supports consistent damping behavior on long descents where heat management and oil control are critical
5. Negative spring top-out control - Reduces harsh top-out feel and improves platform stability for smoother weight transfer and more predictable handling
6. Durability- and consistency-focused internals - CrMo shaft with low-friction coating and high viscosity index oil support smoother action and more stable performance across changing conditions
