The rotation/expansion system traditionally used by most manufacturers to lock the telescopic poles at the correct length did not always ensure a correct engagement of the parts, hence the required reliability during use.
Gipron, thanks to its continuing and fruitful investments in research, was able to perfect the device by developing and patenting the revolutionary Twistlock system. The secret is enclosed inside the pole, and consists of the Powerblast, which is a spindle that has a very long longitudinal bearing surface. Once locked, the poles fitted with Twistlock provide even flexibility and a lock that can withstand extreme stress conditions.
Gipron has fitted its trekking pole collection with Twistlock.
