The 105 front hub is a workhorse. Bill Shook achieved the goal of a front hub with a large 17mm axle and stout 17mm stainless steel bearings. Stiff and strong with big 3.5 mm thick high flanges and the hub is only 105 grams. High hub flanges strengthen the wheel. The hub shell is forged out of one piece of aluminum. The flange cut-outs give the 105 a retro look. Patented bearing sleeve technology for easy adjustability and improved bearing life. Double seal system to keep grit and dirt out of the bearings. This proven design will last for years to come.
