These Eigher brake bars fit the old standard-size aluminum oval and D carabiners as well as 1¾ inch racks.

• The two left-hand bars are typical plain-finished solid aluminum brake bars. I have several versions with differing lengths, end shapes, and markings, but the are all functionally equivalent.


• The third bar is hard anodized. It will wear better than the others and give a smoother, slightly faster descent until the anodizing wears through.


• The right-hand bar is made from 3 m. wall thickness aluminum tube. It is also hard anodized. Once the anodizing wears through, the bar will need to be replaced immediately. If allowed to wear through, resulting sharp-edged hole will be rope-unfriendly. The sharp edge will normally bend inwards, but one should never depend on this.
  

History

Mike Sturm created Eiger Mountain Sports Corp. in the early 1960s. He sourced pitons from Switzerland, and had Stanley Brozek of S.B.C.I. produce carabiners for him. Eiger closed in the early 1970s. After closing Eiger, Mike Sturm built a similar company, Liberty Mountain, and sold climbing gear under that name. Around 1992, Liberty Mountain created the brand Advanced Base Camp for its climbing gear. Advanced Base Camp was reborn as Cypher in 2003.
