The Carbo Ratchamatic is a load-sensing ratchet block designed to roll freely in both directions under low loads and automatically engage the ratchet mechanism as loads increase. This design ensures a seamless transition between ratchet and light-air modes during operation.
Load Sensing: Rolls freely in both directions under low loads and automatically engages the ratchet as loads increase.
Seamless Transition: Shifting between ratchet and light-air modes occurs without interruption.
HTE Version: The spring on the HTE (high-threshold engage) version of the 57 mm blocks is stiffer to delay ratchet engagement.
Free Running: The stiffer spring allows the block to run free more of the time, engaging the ratchet function only at higher loads.
Gybing Performance: Higher load engagement allows the old kite sheet to run free for crisper gybes.
Standard Grip: Optimized for medium to light air conditions with 10:1 holding power.
