New description: [New technical field] This creation is about a bicycle shock absorber, especially the cushioning stroke of the shock absorber is space adjustable. [Prior Art] A bicycle shock absorber is a device that is mounted on a bicycle to slow the vibration of the vehicle body caused by the ground undulation of the bicycle during walking. The internal shock absorber mechanism provides a compression stroke. When the shock absorber is subjected to a vibration, the above-mentioned vibration mitigation can be achieved by damaging the kinetic energy by the displacement of the buffer mechanism in the compression stroke. The custom car depends on the undulating condition of the road on which it travels. When it travels, it will feel different degrees of vibration. When the road is gentle, the vibration is moderate, and when the road is undulating, the vibration is more intense, so the bicycle shock absorber The use of % is expected to adjust the compression stroke of the buffer mechanism, so that when the road surface is undulating and the vibration is severe, the waste @% ti 7 is increased, so that the buffer mechanism can effectively absorb the kinetic energy of the vibration of 4 ft.* +' 4^ ν.λ . _ Either the road surface is fluent or sloping on the uphill road. 7% The compression stroke shortens or even cancels the compression stroke to avoid the rider's pedaling force being absorbed by the buffer mechanism and causing the loss of strength. . , ^ The bicycle shock absorber of the bicycle shock absorber has a dust-reducing schedule designed to be fixed instead of ρ. _ 鲞 因此 因此 既 既 既 既 既 既 既 既 既 既 既 既 既 既 既 既 既 既 既 既 既Straight < + + @ & can only play a good "avoidance effect" on the road conditions corresponding to the § and 疋 屋 屋 行程 行程 行程 , , , , The disadvantages of the poor people, so the existing bicycle shock absorbers still have room for improvement.
