What Our Gearhead(R) Experts Are Saying:"The Grivel Bi-Fold Bar is one of those small upgrades that changes how you think about packing for alpine objectives. Crampons that fold flat take up noticeably less space in a technical pack, and the double-hinged steel construction holds up under load exactly the way you need it to when the points are actually on your boots."Packing for a technical alpine objective is an exercise in making every cubic inch count. The Grivel Bi-Fold Bar adds a double-hinged folding capability to compatible Grivel crampons, letting the crampon collapse for compact storage without sacrificing the structural stability needed when it is actually underfoot on steep terrain. Built into the Grivel Crampon System for interchangeable configuration, the Bi-Fold Bar is a straightforward component upgrade that pays dividends every time you close your pack. Available in three sizes to cover the range of compatible crampon models, the steel construction keeps weight minimal while handling the demands of real mountain use.
