How to fix a bent aluminum trekking pole after a fall on rocky terrain?

A bent aluminum pole can sometimes be straightened, but only if the bend is slight (<15°) and there is no kink or crack. If it's kinked or cracked, replace the section – straightening will weaken it dangerously. For slight bends, remove the bent section and roll it on a flat, hard surface with firm, even pressure. For stubborn bends, gently tap the curve with a rubber mallet. After straightening, reassemble and test the lock – it should hold firmly. If the lock slips or the pole bends again, replace the section – it's been weakened. Safety: Straightened aluminum is weaker. Use the pole only for gentle terrain – avoid heavy loads or steep descents. Replacement sections are available from Decathlon or Adventure Sport.

1. Assessing the damage – can it be fixed?

Before you start, you need to determine whether the pole is repairable or whether it needs a replacement section.

If the bend is more than about 15°, the aluminium has been over‑stretched and will be weak. If the shaft is kinked or cracked, the pole is compromised. In these cases, replace the section.

2. Tools you'll need

• Flat, hard surface – A wooden workbench, a smooth concrete floor, or a flat piece of wood.
• Rubber mallet (optional) – For tapping out stubborn bends.
• Clean cloth – To protect the shaft from scratches.
• Vernier caliper or a ruler – To check straightness.
• Sandpaper (fine grit) – To smooth any sharp edges if the coating has been damaged.

3. Step‑by‑step repair process

a. Remove the bent section – Separate the bent section from the rest of the pole. If it is the lower section, you can usually unscrew or pull it out. For many poles (e.g., Leki Makalu, Decathlon Forclaz), lower sections are replaceable and available as spares.

b. Clean the section – Wipe off any mud or grit to avoid scratching it during the straightening process.

c. Roll the section on a flat surface – Place the section on a flat, hard surface. Roll it under your palm with firm, even pressure. As you roll, the bend will gradually reduce. Rotate the section to work on different parts of the curve. This is the most effective and safest method.

d. Check straightness – Roll the section on the flat surface and watch for any wobble. If it rolls smoothly without lifting off the surface, it is straight. If it still wobbles, repeat the rolling process.

e. For stubborn bends – tapping – If rolling does not fully straighten the section, place it on a piece of wood (to protect the surface) and tap the bent area gently with a rubber mallet. Use light, controlled taps. Do not use a metal hammer – it will dent the shaft.

f. Check again – Roll the section again. If it still wobbles, repeat the process.

4. Testing the straightened section

After straightening, test the section in the pole:

• Slide it back into the pole – It should slide smoothly without binding.
• Close the lock – The lever lock or twist lock should grip securely. If the section is still slightly bent, the lock may not hold.
• Test under load – Put your weight on the pole in a safe place (e.g., at home). If it holds, it is safe. If it bends again or the lock slips, replace the section.

5. When straightening is not safe

• If the section has a kink – The aluminium has yielded and will be weak. Replace it.
• If the section is cracked – It is compromised. Replace it.
• If the lock no longer holds – The section may have been ovalised during the bend. Replace it.
• If the pole is carbon fibre – Do not attempt to straighten carbon. It will splinter.

6. Where to buy replacement sections in Brazil

• Decathlon – Forclaz replacement lower sections. Available in‑store and online.
• Adventure Sport – Leki and Black Diamond replacement sections. Online and in São Paulo/Rio.
• Mercado Livre – Generic sections (check compatibility).

7. Prevention – avoiding bends in the future

• Plant carefully – Avoid planting the pole in gaps between rocks where it can get wedged.
• Shorten on steep ground – A shorter pole reduces leverage and the risk of bending.
• Inspect regularly – After a heavy fall or a hard plant, check the lower section for straightness.

8. Final verdict

A slight bend in an aluminium trekking pole can often be repaired by rolling it on a flat surface. However, if the bend is severe, or if the lock no longer holds, the section should be replaced. Straightened aluminium is weaker and may be more prone to bending again. For safety, test the repaired pole thoroughly before using it on a walk. If in doubt, replace the section – it is a small investment for the safety of your knees and balance. Happy (and safe) hiking!
