4. Rinsten Spring
Rinsten Spring is a bike shock absorber. It offers you comfort during cycling and keeps your body healthy. Installing the 392-gram Rinsten Spring is a little fiddly, but it’s nothing you can’t manage if you already know how to mount the saddle directly on the seatpost. No special tools are required, and it only took me several minutes.
Rinsten Spring mitigates road vibrations and shocks. Rinsten Spring is a groundbreaking system that offers unbeaten comfort and fun during cycling. The retail price is around $50.
