Description
LEKI Code: LESECL40 14 mm Lower Section 420 mm Length Silver Powder CLA 16/14 mm Section Production Era: Approximately 2006–2013
This 14 mm lower section is the correct factory replacement for LEKI’s CLA antishock trekking pole range built on the standard 16/14 mm telescopic geometry — covering models including the Tour CorTec Antishock, Air Thermo long Antishock, Summit AS, and Trail AS. The CLA internal locking mechanism integrates with the pole’s antishock spring system; height adjustment follows the same twist principle as the SLS range: rotate anti-clockwise to release, set height, and rotate clockwise to lock with no external lever required. The silver powder finish (colour code 025) and 420 mm printed length are the defining specifications for this section, covering a wide range of compatible CLA antishock poles produced from approximately 2006 through 2013. From switchback paths through the Cairngorms to long descents on Ben Nevis approach routes, the Tour CorTec and antishock range absorbed impact reliably across demanding mixed terrain. When the lower section is bent, cracked, or the locking mechanism no longer holds under load, this replacement restores the original 14 mm geometry precisely. The 420 mm printed length is specific to this CLA configuration — verify the printed marking on your existing lower section before ordering. Sold as a single section.

► Compatible Poles & Fitting Guide
This lower section is confirmed compatible with the following LEKI CLA antishock trekking poles. Always verify the printed length and diameter on your existing lower section before ordering.
✓ Tour CorTec Antishock — article codes 62027, 72027
✓ Air Thermo long Antishock — article codes 62028, 72028
✓ Summit AS, Trail AS — article codes 82030, 82032, 92030, 92032
✓ Additional confirmed compatible article codes (model names not established from available sources)
✓ Diameter check: This is a 14 mm section in a 16/14 mm profile. Measure the diameter of your existing lower section with calipers before ordering. A section measuring a different diameter requires a different spare part.
✓ Length verification: The 420 mm printed length is the defining specification — measure the printed marking on your existing lower section, not the physical length. A section showing any other printed length requires a different spare part.
✓ Fitting: Rotate the existing lower section anti-clockwise to disengage the CLA lock, then slide it out from the tip end. Insert the new section and rotate clockwise until the lock engages with firm resistance. Test by applying downward load before use.
✓ Lock engagement: The CLA mechanism should engage with a firm, positive resistance when rotated clockwise. If the section rotates freely or fails to hold under load, the internal locking collar may require assessment or replacement.
✓ Not sure? Email photos of the full pole, the damaged section, and any visible article codes to [email protected] so the correct replacement can be confirmed before ordering.
► Not Compatible With
✗ SLS (Super Lock System) poles — different internal locking collar; CLA sections are not interchangeable with standard SLS poles
✗ Speed Lock 1 (SL1) poles — external lever clamping system; entirely different interface from the CLA internal twist-lock mechanism
✗ Speed Lock 2 (SL2) poles — external lever clamping system; entirely different interface from the CLA internal twist-lock mechanism
✗ Poles with a different lower section specification — a different diameter or printed length requires a different spare part; the silver powder finish (025) is a required identifier for this section
BEFORE YOU ORDER — FOUR-POINT CHECK
✓ Printed length: Must read 420 mm on your existing lower section — check the printed marking, not a physical measurement
✓ Diameter: Confirm 14 mm lower section diameter — measure with calipers. This is a 16/14 mm profile section
✓ Locking system: Confirm CLA — the section rotates to lock and unlock with no external lever, integrated with the antishock spring system. If your pole has a Speed Lock lever (SL1 or SL2), this section is not suitable
✓ Construction: 3-section telescopic (Vario) with 16/14 mm section profile — verify the profile matches before ordering
✓ Unsure? Email photos of the full pole, the damaged section, and any visible article codes to [email protected] for confirmation before ordering
