Angelo C. wrote a review of Black Diamond Spire Elliptic Trekking Pole on February 25, 2011
These poles were as advertised but when I used them on the icy trails of the Grand Canyon one pole broke almost immediately. The poles are light, lighter than any other pole I've used. The mixture of foam and rubber in the handles make for a very comfortable grip. The locking mechanism is really convenient, no more twisting and twisting and twisting... But as I said the pole broke. I do not plan on purchasing another pair since the price is steep for a pole that may leave me pole-less for the remainder of my trip. I plan on purchasing a set with similar features at a cheaper price.
