Description
LEKI Code: LESECL29 14 mm Lower Section 490 mm Length Black SLS (Super Lock System) 18/16/14 mm Section Production Era: 2008–2009
The Sierra-FS is LEKI’s fixed-system trekking pole from the 2008–2009 production era, built on a full-diameter 18/16/14 mm three-section aluminium construction with the proven Super Lock System twist collar. Designed for walkers who needed dependable performance on the long gravel tracks of the Pennine Way or the exposed ridgelines of the Lake District fells, the Sierra-FS delivered a sturdy, reliable build in the standard LEKI Black finish. This 490 mm lower section is the tip-end unit and is the component most subject to ground contact and tip wear in daily use. Correct replacement requires verifying both the printed length (490 mm) and diameter (14 mm) on your existing lower section before ordering. The SLS Super Lock System twist collar is specific to this generation and is not interchangeable with any Speed Lock lever design. The 490 mm printed length on your existing section is the definitive identification guide — always confirm this figure before ordering.

► Compatible Poles & Fitting Guide
LESECL29 is confirmed compatible with the following LEKI poles where identification has been established from official LEKI product records. Always verify against the 490 mm printed length and 14 mm diameter on your existing lower section — these measurements override model name matching.
✓ Sierra-FS — article codes 082092, 092092
✓ Additional confirmed compatible article codes (model names not established from available sources): 6352092
✓ Twist the SLS collar at the base of the middle section anti-clockwise to release the lower section. Insert the replacement 490 mm section from below until it seats fully at the internal stop. Twist the collar clockwise until firmly locked. Pull-test the joint before use to confirm no slip or rotation.
✓ SLS lock verification: apply firm downward pressure on the tip of the fully assembled pole; the lower section must not slip, extend, or rotate. Any movement indicates incomplete locking or collar wear requiring attention before use on trail.
✓ SLS identification: the twist collar is visible at the base of the middle section; no external levers are present on the pole shaft. The collar operates by mechanical friction with a smooth rotational action.
✓ Diameter check: this section is 14 mm and suits the full-diameter 18/16/14 mm Sierra-FS construction; do not confuse with 12 mm lower sections from lighter-profile LEKI trekking poles of the same era.
✓ Age check: Sierra-FS sections from 2008–2009 are now 16–17 years old; inspect the SLS twist collar threads, lower section surface, and tip socket for corrosion or wear before fitting.
► Not Compatible With
✗ Speed Lock 1 (SL1) or Speed Lock 2 (SL2) external lever systems — completely different locking mechanism; lever collar cannot engage with the SLS twist design
✗ Speed Lock + (SL+) or Speed Lock 2+ (SL2+) external lever systems — lever-based geometry will not engage with the SLS twist collar on this section
✗ Classic Lock twist collar — different thread pitch and collar geometry; may appear similar to SLS but will not lock correctly
✗ Poles whose existing lower section is not marked 490 mm — the printed length is the definitive check; do not order based on model name or diameter alone
BEFORE YOU ORDER — FOUR-POINT CHECK
✓ Printed length: 490 mm — confirm this figure is printed on your existing lower section before ordering
✓ Diameter: 14 mm — verify the diameter marked on your existing lower section is 14 mm; this is the innermost section of an 18/16/14 mm pole
✓ Locking system: SLS Super Lock System — twist collar at the base of the middle section; no external lever present; confirmed on 2008–2009 Sierra-FS poles
✓ Construction: Three-section telescopic aluminium with 18/16/14 mm profile; verify all three sections collapse and extend smoothly after fitting the replacement lower section
