The Smart Traveller Carbon is LEKI’s lightweight SLS travel and trekking pole built from carbon fibre, designed for distance hikers and backpackers who need minimum weight without sacrificing reliability — at home on a long-distance route through the Alps or a multi-day walk across the Cairngorms. LESECL109 is the genuine LEKI replacement lower section for this pole: 12 mm in diameter, 435 mm printed length, finished in Carbon/Black, and built for the SLS internal twist-lock interface. It covers the Smart Traveller Carbon across its production run from approximately 2017 to 2018. Carbon sections require the same SLS verification as aluminium but demand an additional inspection step: check the tube surface for cracks or white stress marks before fitting, as carbon can fracture at impact damage sites that are not immediately visible. LESECL109 restores the original 12 mm diameter and 435 mm printed length, ensuring the SLS collar seats and locks correctly. The 435 mm printed length on your existing lower section is the check that matters — confirm this number before ordering, as other LEKI SLS carbon sections are specified to different lengths.

► Compatible Poles & Fitting Guide
LESECL109 is confirmed compatible with the following LEKI poles where identification has been established from official LEKI product records. Always verify against the 435 mm printed length and 12 mm diameter on your existing lower section — these measurements override model name matching.
✓ Smart Traveller Carbon — article code 6402606
✓ To fit: twist the SLS collar at the base of the middle section anti-clockwise to release. The lower section slides free. Insert LESECL109 from below until the internal stop is reached. Twist the collar clockwise until it locks with a firm stop. Set to your required length and pull-test before use.
✓ SLS lock check: after fitting, apply firm downward pressure on the tip. The section must not slip or rotate. The SLS mechanism is fixed-tension — a collar that does not hold after correct fitting requires replacement.
✓ Carbon section inspection: before fitting, examine the tube surface for cracks or white stress marks. Carbon can fracture at impact damage sites that are not immediately visible — do not fit a damaged carbon section.
✓ SLS identification: rotate the collar at the joint between the lower and middle sections anti-clockwise to release. An external lever at this joint means Speed Lock, not SLS — not compatible.
✓ After locking, check for any audible play or rattle between sections; movement indicates incomplete seating or collar wear.
✓ The collar must thread smoothly and lock with consistent tension; rough threading indicates grit in the mechanism — clean before fitting.
► Not Compatible With
✗ Speed Lock 1 (SL1) poles — external lever clamp with different tube interface; not interchangeable with the SLS internal twist-lock
✗ Speed Lock 2 (SL2) or Speed Lock + (SL+) poles — lever-based locking systems with incompatible section geometry
✗ SLS poles with a 14 mm lower section — LESECL109 is 12 mm; diameters are not interchangeable
✗ Poles whose existing lower section is not marked 435 mm — any other printed length means a different section is required
BEFORE YOU ORDER — FOUR-POINT CHECK
✓ Printed length: existing lower section must be marked 435 mm — primary identifier, takes precedence over model name or colour
✓ Diameter: tip end must measure 12 mm — confirm with a calliper or product documentation
✓ Locking system: pole must use SLS (Super Lock System) — internal twist collar at the lower joint; an external lever means Speed Lock and this section will not fit
✓ Construction: 3-section telescopic with 16/14/12 mm profile — middle section must be 14 mm where it meets the lower joint
