Great addition to Chubbie

Bought this an an addition to my Chubbie 2. Definitely worth it for a smoother ride.

Brad · April 15, 2026

excellent service

fast and easy

Jay · March 24, 2026

It doesn't really add much to the chubbies sprung seat.

I feel that this was probably an unnecessary purchase. The seat turned out to be very comfortable and well sprung already. It works fine, but would I have brought it in retrospect? Probably not.
