Abstract
A bicycle braking device includes a caliper, two operation units and two links. Each operation unit is installed to the two respectively threaded holes of the caliper and includes an operation assembly and a ring. Two links are respectively connected to the two operation assemblies. Each operation assembly includes multiple curve slots, and multiple balls are partially rotatably accommodated in each curve slot. Each ring is movably mounted to the core part of each operation assembly and includes multiple spiral grooves. The balls are accommodated in the spiral grooves and the curve slots. When the two links are pivoted by pulling the brake cable, the two core parts are rotated, and the two rings rotatably move to push the linings to clamp the brake disk. The balls ensure the rings to move smoothly so as to precisely clamp the brake disk.

Abstract
A tire valve assembly includes a stem and a valve unit. The valve unit includes a movable part and a seal member. When introducing pressurized air into the tire valve assembly, the valve unit moves to a position in the stem to allow the pressurized air to flow into the tire. When the pressurized air is stopped from entering the tire valve assembly, the valve unit is pushed back by the pressure in the tire to seal the inlet so that the pressurized air in the tire does not leak to keep the tire pressure.

Abstract
A tire valve assembly includes a valve shaft movably inserted into a first diameter section of the outer tube. The valve shaft includes a passage and a radial hole which communicates with the passage. A first seal is mounted to the end of the valve shaft that is inserted into the outer tube and is movable relative to a shoulder in the outer tube. A guide tube is mounted to the valve shaft and has a guide portion protruding therefrom which is guided in guide groove in the outer tube. An adjustment tube is threadedly mounted to the first outer threads on the valve shaft. When rotating the adjustment tube, the valve shaft is axially movable in the outer tube to control the gap between the first seal and the shoulder in the outer tube. The gap is changeable and communicates with the radial hole and the passage.
