Just like the portable drill for plaisir climbing, the development of camming devices was THE breakthrough for clean climbing which made it a sport not only for superhumans.

In 1973 Greg Lowe filed for a patent for a spring-loaded version of the Abalakov Cam. Ray designed a spring-loaded opposing multiple cam unit with a more stable 13.75 degree camming angle and an innovative triggering mechanism.

is perhaps not the most stylishly designed cams site, nor does it have a huge number of performers online, but once you get to know it you will find that it has everything you need.

Because of the large forces which are exerted on the rock when an SLCD is fallen on, it is very important that SLCDs are only placed in solid, strong rock.
