The hardest part is the lightweight construction, the top one leaves every other week (= 100 km of skiing)
I just added spikes to my Swix poles.
Works
Excellent product, already purchased in the past, I highly recommend it
Good blades for roller skiing.
Ok
I ordered new spikes for skating poles with a grade of 10
Complies with the description. For its lifespan, see the use. In principle, a set of spikes lasts me 6 months.
The spikes of the walking sticks bite into the ice like hot naskali butter, I recommend.
Very good material
