Rinsten spring is a bike accessory that reduces the vibration from the seat for cyclists.
A cyclist experiences the same amount of vibration in an hour a tractor driver experiences in six hours, according to a study by the University of the West of England.
Rinsten Spring can absorb shocks from three directions. The user can control the rigidness of the spring according to individual preference.
The user can install the spring between the seat post and the saddle of a bicycle.
The spring can hold riders up to 400 kilograms or 882 pounds.
Iurii Kopytsia, CEO and founder of Rinsten said the company’s bench test shows the spring can remain operable when the load reaches 400 kilograms (882 pounds).
“That is why we are pretty confident in our product and can offer our customers of up to 150 kilograms (330 pounds) lifetime warranty,” Kopytsia said.
It takes about 10 minutes to install the spring with standard toolkits.
The spring fits almost all modern bicycles today.
Rinsten spring is available in gold, silver or black. The shock absorber retails at $59.99, including free worldwide shipping.
