shoowrote a review of Black Diamond Cyborg Pro Crampons on November 21, 2011
Though something tells me the new Petzl Lynx is going to put the cyborgs out of business, these are really a fantastic set of technical climbing crampons. They have a great fit to most modern climbing boots (some adjustment of the front bail would be helpful). The replaceable points are very handy, makes sharpening and replacing cheap and relatively easy. The ability to switch between dual and mono is invaluable. They are my default crampons for everything technical (steep waterfall ice, mixed, and pure dry tooling). While I am listing a few noticeable flaws below, it's worth noting that I am overall pretty happy with my purchase.
Flaw #1) It's NOT all-stainless. There are two key parts which are cro-moly steel: the bolts holding the front points, and the front points themselves. Mixing stainless and non-stainless steel parts INCREASES the rate of rust due to galvanic corrosion. I am a bit disappointed that a stainless bolt wasn't included for this reason, or at least free replacement bolts. There is also rust where the front points meet the holding bar. Bolt rust on mine is to the point where it is very difficult to change the points, and where breakage may occur, and I take VERY good care to try to keep them dry post-climb.
Flaw #2: You have to manually dissect the anti balling plates to use them in mono. It would have been fairly easy to just make a plate in which this is not an issue.
