    StarStarStarStarStar Ahhh

    Ownership: several months
    Tech Knowledge: average


    Easy to install.
    Improves ride over uneven surfaces.
    Saves your back and butt so you can ride longer.
    Excellent quality.



    Other Thoughts

    Overall a great product. As an average rider this was an excellent compromise to upgrade a hard tail over buying a new full suspension bike.

    I purchased 2 Thudbuster LT seat posts. Product works as advertised. Reasonable suspension travel and rebound.
    Changeable rubber elastomers "springs" allow adjustment for rider weight and terrain.


    The #7 Rubber Elastomer is difficult to locate and buy. For riders wearing back packs or weighing 200 LBS. 90 kg. The combination of #5 and #7 Elastomers may be the preferred suspension combination. The Thudbuster LT comes with #3 and #5 Elastomers, giving good pre-load and comfort for 170 Lb. 77 kg. riders

    Be absolutely sure you have 4'' to 5'' of exposed seat post on your current bike frame and seat combination! The Thudbuster LTsuspension mechanism is 5" high unloaded and fits between the seat and bike frame. Be darn sure you are comfortable on your bike with the seat raised 4" to 5" before buying a Thudbuster LT.

    Other Thoughts

    Carefully measure the seat post you want to replace with a Thudbuster LT seat post. Seat post diameter should be stamped toward the lower end of the post. There are many many seat post diameters! A wide variety of seatpost shims are available to adapt Thudbuster seat posts to your bicycle down tube diameter. You may be able to buy multiple adapter bushings and just one Thudbuster seat post to use on multiple bicycles.
    Be exact when purchasing seatpost shims and seatposts!

    This suspension seat really helps! I'm retired with a bad back, 2 operations and the bumps are bad for me on my spine. Have have spinal fusion and laminectomy. So, I ride real slow to reduce bumps, and still had issues. So, I spent the money and put this thing on it. It really improved my life on the bike. I'm not jumping on a mountain bike which may be the customer base, but this is good, and I'm heavy too.


    The only thing I don't like is this item costs a lot, but it is built real well, and a speciality item. Other than that, no issue.

    The seatpost diameter must match to the seat tube diamater of your frame. If replacing a seatpost, you can usually find this measurement etched near the bottom of your current post.

    Seatpost length is measured in millimeters. It is typically measured from the bottom of the post to the center of the rail mount.

    Offset is often referred to as setback. This is the distance in mm that the clamp is offset from the center of the seatpost.


    Suspension seatposts are designed with comfort in mind.
