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

Revainrating 4 out of 5

Simple, high quality and cheap. What's not to like?

I mounted this unit on a hardtail e-bike with fat tires and an oversized seat. I mostly drive on gravel roads, which can be pretty bumpy. I installed the unit upside down to reduce side roll and it worked. Even though I'm only 145 pounds, I set the tension to the heaviest fit. I recently rode 30 miles on a rough forest road and this inexpensive seatpost spring has performed well. Simple, high quality and cheap. What's not to like?
