LOCK­ING MECH­A­NISM

Trail (UK) - - Best Of Your Budget -

Length is usu­ally ad­justed by an ex­ter­nal lever, op­er­at­ing a clamp­ing mech­a­nism (the flicky kind); or by an in­ter­nal ex­pand­ing clamp­ing sys­tem (the twisty ver­sion). The lat­ter doesn't snag on rocks or un­der­growth, but the poles will need dry­ing af­ter use to pre­vent cor­ro­sion cuased by in­ter­nal mois­ture build-up. The lever mech­a­nism is gain­ing pop­u­lar­ity as it's quick and easy to use, and ap­pears not to suc­cumb to op­er­at­ing prob­lems eas­ily, but it can snag on un­der­growth.
