An aerodynamic bicycle rim comprising: a circumferential outer portion comprising a circumferential outer surface, the circumferential outer portion adapted to seat a bicycle tire; a nose; and a set of sidewalls, each sidewall extending radially from the nose of the aerodynamic bicycle rim to a corresponding transition to the circumferential outer surface to form a rim body having a maximum rim body width that is greater than a maximum width of the bicycle tire. The aerodynamic bicycle rim is operable to seat the bicycle tire so that the aerodynamic bicycle rim and the bicycle tire form an asymmetrical cross-sectional shape.

A hydraulic braking system connector comprises a first coupling terminal having an annular abutment surface, a coupling sleeve having a first axially outer annular portion, receiving the first coupling terminal, an annular wall with a first annular abutment surface to abut the first coupling terminal abutment, and a second axially outer annular portion, to be coupled with a component of the hydraulic braking system. A first annular locking element is axially moveable between a rest position and a locking position. A first annular hydraulic sealing element is configured to be activated by the first annular locking element when in the locking position. The annular abutment surface of the first coupling terminal is in abutment on the first annular abutment surface of the coupling sleeve when the first annular locking element is in the rest position.

The present invention relates to a freewheel hub for a bicycle, comprising a freewheel device which optionally allows relative rotation between a hub sleeve and a driver or couples the hub sleeve and the driver in a torque-transmitting manner. The freewheel device has at least one first clutch ring and at least one second clutch ring, wherein the first clutch ring is coupled or coupleable to the hub sleeve in a torque-transmitting manner, and wherein the second clutch ring is coupleable or coupled to the driver in a torque-transmitting manner, and wherein the first and the second clutch ring are displaceable axially relative to the hub axle between an engaged position and a freewheel position. Provision is made here for at least one magnet arrangement accommodated in apertures in the first clutch ring to keep the clutch rings in the engaged position.

An aerodynamic bicycle rim, the bicycle rim comprising a circumferential clincher portion adapted to seat a clincher bicycle tire, a nose a set of sidewalls, each sidewall extending radially from the nose to a respective circumferential outer edge to form a rim body having a maximum rim body width that is greater than a maximum width of the clincher bicycle tire and spaced radially inward of the clincher portion and radially outward from a centerline of the rim body.

Embodiments described herein provide aerodynamic bicycle rims and wheels. Embodiments can include a bicycle rim that is wider than the width of the tire proximate to the outer edge of the rim and is shaped so that there is a tangent line tangent to the rim and the tire. The tangent line can be tangent to the rim on the sidewall or elsewhere on the rim. The widest part of the rim can be radially inward from the outer edge of the rim or elsewhere on the rim and the tangent line can be tangent at the widest part of the rim or elsewhere on the rim.
