LEKI Speed Lock explained: types, differences and how to adjust them
If you own adjustable LEKI poles, the little lever that sets and holds your length is a Speed Lock (often written Speedlock). It is the mechanism that lets you shorten for the climb and lengthen for the descent, and get it set right and it simply disappears into the walk. Here is what a Speed Lock is, the main types, how to tell which you have, and how to adjust one properly.
What is a LEKI Speed Lock? A LEKI Speed Lock is an external lever-clamp that sets and holds the length of a telescopic pole. Unlike an internal twist lock, the lever squeezes the inner section firmly, and its grip is fine-tuned with a small tension screw. It is quick to open and close, works with gloves on, and is TUV-tested for holding force.
How a Speed Lock works
A Speed Lock is an external clamp fitted where two pole sections meet. Flip the lever open and the inner section slides freely so you can set your length; close the lever and it grips the tube firmly so the pole holds under load. A small screw or wheel adjusts how tightly the lever bites, so you can keep the clamp secure as parts settle with use. Because it works from the outside, you can see and feel that it is locked, and operate it wearing gloves.
The main types of Speed Lock
Speed Lock 2 Plus (SL2+)
The current standard on most adjustable LEKI poles. It holds more than 90 kg, yet it is around 33 percent smaller and 25 percent lighter than the original Speed Lock 1. If your poles are recent, this is almost certainly what you have.
Speed Lock Plus (SL+)
A slightly lighter-duty clamp holding more than 75 kg, used across the standard range. Plenty secure for general walking and trekking loads.
Speed Lock 1 (SL1)
The earlier, larger version still found on some older poles. It works exactly the same way; it is simply bigger and heavier than the current SL2 Plus.
Older poles and entry lines may instead use the internal Super Lock System (SLS), a twist lock that expands inside the tube. It is reliable but slower to use than an external Speed Lock.
How to identify which Speed Lock you have
Two quick checks tell you which clamp is on your poles. First, look at the section size and lever: the current SL2 Plus is notably more compact than the older, chunkier SL1. Second, check whether the lock is external (a visible lever clamp, so a Speed Lock) or internal (you twist the sections against each other, so an SLS). If you plan to order a replacement part, note the section diameter printed near the clamp, as parts are matched to tube size.
How to adjust and tension a Speed Lock
Adjusting is simple. Open the lever, slide the section to your chosen length against the printed scale, then close the lever until it snaps firmly shut. If the lever closes too easily and the pole slips, open it and turn the tension screw a little tighter, then test again; if it will not close, loosen it slightly. Aim for a firm, positive click, and always check both clamps hold before you set off. The video below shows length adjustment in practice.
Spare parts and repairs
A Speed Lock is a serviceable part, not a sealed unit. Worn levers, tension screws and whole clamp assemblies can be replaced, and LEKI stocks spare parts for roughly ten years after a model launches. If a clamp will not hold even at full tension, or a lever cracks, it is usually a cheap part swap rather than a new pole, in keeping with the repair-first way LEKI builds its kit.
Frequently asked questions
What is the difference between Speed Lock and Speed Lock 2 Plus?+
Speed Lock is the family name for LEKI's external lever clamp. Speed Lock 2 Plus is the current version: it holds more than 90 kg and is around a third smaller and a quarter lighter than the original Speed Lock 1.
My LEKI pole keeps slipping. How do I fix it?+
Open the clamp and turn the small tension screw a little tighter, then close the lever and test under load. Repeat in small steps until the pole holds firmly. If it still slips at full tension, the clamp or an internal part may be worn and need replacing.
How can I tell which locking system my poles use?+
If there is a visible external lever you flip open and shut, it is a Speed Lock. If you lengthen the pole by twisting the sections against each other, it is the internal Super Lock System. The current external clamp, SL2 Plus, is compact compared with the older SL1.
Can I replace a broken Speed Lock myself?+
Often, yes. Levers, tension screws and clamp assemblies are available as spare parts matched to your tube diameter. For anything involving internal components, or if you are unsure of the part, it is worth checking the fit before ordering.
The bottom line
The Speed Lock is what makes a LEKI pole adjustable: an external lever clamp that is quick, secure and easy to service. Know which one you have, keep it tensioned correctly, and replace worn parts rather than the whole pole. If you are choosing new poles, the LEKI Pole Finder points you to the right adjustable model.
Adjustable LEKI poles that use the Speed Lock include the Makalu FX Carbon, the Khumbu and the value Legacy Lite.
