Review on 🚲 splumzer ZTZ Bicycle Shock Absorber: Ultimate Suspension Device for Road Bike Seat – Alloy Spring Steel, High-Performance Cycling Parts by Michael Colley

Works fine as long as it works. However, its design gave me concerns from the start due to its extreme susceptibility to metal fatigue issues due to its design, but I chose it anyway based on the good reviews. However, after about 3,000 miles of driving (I weigh about 155 pounds) the spring failed and burst while driving, which could very easily lead to a serious accident. I'm lucky, but it's not worth the risk to me. I have a second one on a different bike but I will take it off and throw it away before it happens again with potentially more serious consequences. I will try something else.
