The outer profiles of the carrier bodies of the sprocket carriers are different from each other. The bearing units of the sprocket carriers are the same in total length and inner diameter for being alternatively mounted on a carrier-mounting section of the axle member. | 10-23-2014 |
| 20150314641 | BICYCLE HUB ASSEMBLY - A bicycle hub assembly comprises a hub axle, a hub shell, and a sprocket supporting member. The sprocket supporting member comprises a tubular portion and a first tooth. The tubular portion includes an outer peripheral surface and an attachment portion provided only radially inward of the outer peripheral surface. The first tooth is configured to be attached to the attachment portion of the tubular portion. The first tooth comprises a first surface and a second surface. The first surface is configured to face a mounting portion of a bicycle sprocket in a circumferential direction of the sprocket supporting member. The second surface is opposite to the first surface in the circumferential direction. The second surface is configured to face the mounting portion of the bicycle sprocket in the circumferential direction. | 11-05-2015 |
| 20150314642 | FREEWHEEL HUB - The present disclosure provides a bicycle hub that provides improved drive line efficiency and bike-to-rider torque feedback. The drive line efficiencies are due to lower rolling resistance resulting from a novel bearing and sprag clutch configuration, a lightweight design, and immediate torque transfer from the cassette drive to the hub body. The bike-to-rider feedback has been improved as the torque transfer is smooth, predictable, and immediate. | 11-05-2015 |

| 20160052337 | ANTI-SLIP DEVICE FOR A HUB OF A BICYCLE - An anti-slip device for a hub of a bicycle is provided for a first engaging element and a second engaging element between a bicycle hub and a chain wheel drive seat of the bicycle. A second engaging element has one side facing the chain wheel drive seat and including indentations equally defined therein. Each indentation has a bottom and a protrusion extending from one end of the bottom, wherein protrusion has a shoulder and a distal end. The chain wheel drive seat has multiple curved control blocks laterally extending therefrom, wherein the multiple curved control blocks are annularly arranged. Each curved control block is movably received in a corresponding one of the indentations and a circle difference is formed between the corresponded curved control block and the indentation. | 02-25-2016 |
| 20160137256 | WHEEL SECURING AXLE AND BICYCLE HUB ASSEMBLY - A wheel securing axle includes a shaft that includes a first end portion, a second end portion including a thread, and a shaft axis, a washer rotationally supported by the first end portion of the shaft, and a click mechanism arranged between the shaft and the washer. | 05-19-2016 |
| 20160375950 | SKEWER AND HUB FOR CYCLE WHEEL - A skewer for fixing a wheel to a cycle-type vehicle, comprising a rod extending along a longitudinal axis, a first end that includes structural elements that cooperate with the vehicle frame, and a second end that includes structural elements configured to cooperate with a device exerting a tightening torque, in which the rod includes a groove extending along the longitudinal axis over a first length, an element having a variable diameter and a second length, the second length being less than the first length, is received in the groove so as to be translationally movable along the longitudinal axis, and an elastic biaser longitudinally constrains the variable diameter element towards the second end. The variable diameter element is a split tubular ring whose diameter in the free state is greater than the maximum outer diameter of the rod; it is longitudinally constrained by a spiral spring, and a distribution ring is interposed between the spring and the variable diameter element. | 12-29-2016 |
