The Helinox LBB 135 trekking pole uses a combination of the vertical lever system and a button system, both are specially designed for the Helinox poles. Aligning the lever vertically with the length of the pole makes a longer lever, for easier operation, possible without creating a protuberance problem. The dual cam system spreads the load, substantially reduces the change of deformation and ensures high locking forces for more reliable performance. The Lever Resting Zone relieves all pressure on the mechanism when the pole is compacted and not in use. The button system with an internal rail system prevents relative rotation of the sections and allows “one touch” operation. There is now no need for the frustrating manipulation required to align the buttons with the button holes. The ball bearing allows increased spring tension to ensure the button emerges consistently to reliably lock the pole. The Helinox dual button system spreads the load evenly so that the load on each button is halved for more reliable operation. Combined with the unique TH72M alloy the mechanisms create a reliable, lightweight trekking pole with a very small pack size.
