The Thudbuster LT G4 suspension seatpost has allowed me to have a comfortable ride on my new ebike which has a front shock but has a hard tail. I have a lower vertbrae, L5-S1 that is deteriating. Cracks in roads, dirt roads, and unforseen bumps were jaring to me. I decided on the Thudbuster and am impressed. It absorbs nearly all but the biggest bumps( I slow down for them so they aren't an issue) and has made my rides fun and enjoyable. I bought a sleeve shim as its post diameter did not fit my bike. Be aware that if you are short it may not work for you because the elastomeric piece raised the minimum seat height about 5". Without the seatpost raised it is a perfect height for road riding (I'm 5'-10"). If you are an aggressive rider going down hill on single track may cause you problems because of a higher center of gravity.Read full review

Go back to the old design. The new design dont have extra elastomers included like the older ST had. Its more difficult ( very difficult ) to adjust the saddle. I do have 3 old ST Thudbusters and love them but was dissapointed with the new LT G4 design.

The Thudbuster adds 5" to the seat height making it unusable.

Absorbs bumps well. Prefer over the ST version with a shorter distance to travel. Additional elastomers available for different weight resistance but at an additional cost.

Worth every penny. Wish I had bought one a long time ago. You won't be disappointed, but will be surprised what a difference it makes. tc
