This high-quality Asahi LIGHTOOL 72 teeth 3/8" ratchet weighs only 178 grams ( 6.3 oz), is up to 40% lighter than most 3/8' ratchets, and is as strong. This ratchet is a must-have for any rider who wants to minimize tool weight.
Many riders opt for a 1/4-inch drive. However, that limits you to sockets up to about 13mm due to the maximum torque you can apply to 1/4-inch ratchets. However, if you want to carry a few larger sockets, such as 17mm or 19 mm, you need 3/8" drive tools such as this Asahi LIGHTOOL ratchet.
It is not that much heavier than, for example, a Wera Zyklops 1/4" drive which weighs 107 grams (3.8 oz). Add a 3/8" to 1/4" socket adapter, and you still save weight using 1/4 sockets and bits while at the same time having the option to use larger sized 3/8" tooling.
There's also a 3/8" to 1/2" socket adapter for larger-sized tooling in the workshop.
