MEGA UPDATE! Here are several new patent applications that may hint at future development in the mountain bike world:

SRAM has several things seemingly in the works, the most interesting of which include a hydraulically damped rear derailleur to replace a traditional friction-style clutch mechanism. Claimed benefits include less force while shifting, more consistent production, and may make for more reliable chain tension over time.
USPTO Application # 20180274623: Fluid damper for a bicycle component by Sram, Llc
"A bicycle rear derailleur has a base member mountable to a bicycle frame, a movable member movably coupled to the base member, a chain guide assembly rotatably connected to the movable member for rotation about a rotational axis, a biasing element configured and arranged to bias the chain guide assembly for rotation in a first rotational direction with respect to the movable member, and a fluid damper having a fluid cavity containing a volume of fluid."

USPTO Application # 20180186419 : Adjustable seatpost by Sram, Llc
"A seat post assembly for a bicycle has a first tube with a first distal end and a second tube with a second distal end. The first and second tubes are movable relative to one another to establish a distance between the first and second distal ends. A first pressure chamber has a loaded pressure proportional to a load applied along the tube axis. A second pressure chamber has a second pressure not proportional to the load."

USPTO Application # 20180257737: Bicycle electric telescopic apparatus, bicycle power supply system, and bicycle electric component system by Shimano Inc.
"A bicycle electric telescopic apparatus comprises a first tube, a second tube, a positioning structure, an electric positioning actuator, and a power supply. The first tube has a center axis. The second tube is telescopically received in the first tube. The positioning structure is configured to relatively position the first tube and the second tube in a telescopic direction extending along the center axis of the first tube."

USPTO Application # 20180079462: Bicycle telescopic apparatus by Shimano Inc.
"A bicycle telescopic apparatus includes a first tube having a receiving space, a second tube telescopically received in the receiving space of the first tube, a position detector configured to detect a relative position between the first tube and the second tube in a longitudinal direction of the bicycle telescopic apparatus, and an output device configured to output a signal based on a detected result of the position detector. The signal can control a bicycle component other than the bicycle telescopic apparatus. A detecting point of the position detector is located in the receiving space of the first tube."

USPTO Application # 20180072370: Bicycle component operating apparatus by Shimano Inc.
"A bicycle component operating apparatus includes a first operating device and a second operating device. The first operating device includes a base member, a main body and an operating member. The base member has a clamp configured to be coupled to a handlebar. The operating member is movably arranged with respect to the base member. The operating device member is configured to perform an operation of at least one of a bicycle transmission component and a bicycle brake..."

USPTO Application # 20180086412: Bicycle operation device by Shimano Inc.
"A bicycle operation device includes a clamp and an operation unit. The clamp is attachable to a handlebar of a bicycle. The operation unit includes a wireless communicator configured to communicate with a bicycle component and an electric switch configured to transmit a signal to the wireless communicator. The operation unit is attachable to the clamp in a manner allowing for adjustment of the position of the operation unit relative to the clamp."

USPTO Application # 20180265153: Bicycle suspension tube and bicycle suspension fork by Shimano Inc.
"A bicycle suspension tube comprises a tubular body, a wheel attachment part, and a caliper attachment part. The wheel attachment part is provided on the tubular body. The wheel attachment part includes an attachment hole having a rotational center axis. The caliper attachment part is provided on the tubular body. The caliper attachment part includes a first through hole having a first longitudinal axis non-parallel to the rotational center axis."


USPTO Application # 20170334514: Bicycle system and automatic control system thereof by Giant Manufacturing Co., Ltd.
"An automatic control method suitable for a bicycle system is provided. The bicycle system has a gear ratio and a toque ratio formed by an auxiliary torque and a pedaling torque. The automatic control method includes following steps: sensing a pedaling cadence and the pedaling torque of the bicycle system in a riding state; setting a first cadence threshold and a second cadence threshold according to a preset pedaling cadence while the first cadence threshold is greater..."

USPTO Application # 20180037295: Bicycle rear suspension system by Level One Engineering Llc
"A bicycle may include a front triangle and a rear suspension system that couples the front triangle to a rear wheel and is dampened by at least one shock absorber. The rear suspension system includes a six-bar linkage having two ternary links separated from each other by one or more binary links, such that the two ternary links do not share a common joint. One of the ternary links may comprise a chain stay. In some examples, the other ternary link may comprise the front..."


USPTO Application # 20180148123: Suspension for a bicycle by Brent Neilson
"Disclosed is a suspension for a bicycle. The suspension has a swingarm having a front and rear end and wherein the rear end is configured to attach to a rear wheel of a bicycle, an upper and lower link both adapted to pivotally connect the swing arm to the frame of a bicycle, and a jackshaft having a drive side and a non drive side sprocket and being connected to the front end of the swingarm, the suspension configured such that when in use with a bicycle, a chain connects... "

USPTO Application # 20180148130: Lever driven bicycle with synchronous drive ratio control by John H. Staehlin
"A lever driven bicycle with synchronous drive ratio control is disclosed. The lever driven bicycle may include a pair of drive levers pivotable around an axis. The lever driven bicycle may also include a force applicator connected to each drive lever, each force applicator configured to receive an application of a force to rotate a drive wheel. The lever driven bicycle may further include a control mechanism connected to the pair of drive levers, the control mechanism configured to synchronously adjust a drive ratio of each drive lever."
