The folks at Tree have decided to make a 3/8″ bolt version of their current rear hub. This hub is for all the trails, pegless street, and park riders out there who just want to run 3/8″ axles. It has all the same features of their current hub but comes with a 17mm 7075 T6 aluminum center axle and 3/8″ heat treated steel bolts. With a 9T cog it weighs only 370grams/13.2 ounces! Tree have a couple of new hubs available and one for racing too.
