We have another prototype version of our hubs being tested. Earlier this year we tested 14mm 7075-T6 aluminum bolts and center axle in our rear hub. We had good results, so now we are giving it a go in the front hub. We have started testing, the hub is very light at 6.3 ounces, which is 2.2 ounces lighter than our current front hub with 3/8″ bolts. We are sure it will not only be lighter, but also stronger than any front hub using 3/8″ steel axles or bolts.
