Name: Green 2cam - Edavidso
Total Score: 93.43
Range: 19.3 24.2mm
Weight: 48.2 grams
Strength: 6.01 kN
Failure Mode: Axle supports on the cam lobes buckled
Video: Link
Comments: Very nicely made but had some issues with the stem buckling when the trigger was pulled, which made getting the cam fully retracted difficult. An overly narrow trigger bar didn't help things either. Anyway, it turns out that the interlocking cam lobe supports were a major weak point and caused the unit to fail at a surprisingly low force. Perhaps there's enough room in there to widen them, otherwise switching over to a stronger alloy might be necessary.
