SONA conical type bicycle hub with quick release, model SC-HB-105, for front and rear bicycle wheels. The front hub is sized 3/8" X 5 1/2" and the rear 3/8" X 7", with spoke holes to order. A quick-release lever clamps the hub into the frame or fork, so the wheel can be taken off and refitted by hand. Each hub has a silver shell marked SONA, two drilled spoke flanges, a black quick-release lever on one side and a black conical nut on the other.
