Ronstan Ratcheting Pulleys (Pair)
These ratcheting pulleys can be fitted to almost all harness, and are very easy to install. These pulleys hold the tension on any amount of speed bar. They easily release the speed bar line when tension is released. The combination of the larger diameter pulley and ratchet system save you tons of energy in your your legs on long flights. It makes a huge difference on long XC mission and racing since you aren’t wasting energy unnecessarily. Sold as a pair.
