Cane Creek Thudbuster LT 3G Seatpost

By adding the Cane Creek Thudbuster rear suspension you'll ride faster, longer, and stronger with better traction, more control, and less fatigue. The performance, relative low weight, and simplicity make it the best suspension upgrade you can make to your hardtail.

Based on a patented parallel-linkage design, the Cane Creek Thudbuster LT provides up to 3 inches of active stiction-free travel. Unlike telescoping suspension posts, there is no initial stiction to overcome-the suspension mechanism works in the direct path of the natural travel of the rear wheel. The elastomers provide the compression and rebound damping, and can be easily exchanged to tune the suspension.

  • Includes (2) No. 5 elastomers installed and (1) No. 3 and (1) No. 7
  • Other Densities/Colors sold separately

Q: Which thud buster seat post the ST or LT works best for a hard tail 29er

A: A lot of people would opt for the LT since the ST can feel like a traditional seatpost with minor bump absorption (good for road/firetrail use when it comes to small rocks/bumps) and the LT would be good for the same yet with more suspension. It's all a matter of preference from here. Feel free to shoot us an email if you have any further questions.

Only Suspension Seat Post Design Worth Considering - Oct 26, 2015

If you must use a suspension seatpost, then there really aren't any other good options. Straight suspension posts shorten the distance between your saddle and pedals under compression. This one does not. I would personally rather go for a dropper post and absorb the shock with my legs, but I get why this post appeals to so many people. It is also absolutely necessary for stokers on mountain tandems. Because the stoker cannot see any upcoming bumps, this is a humane way to save their butts and probably save the marriage as well.

When I first bought this product, I was riding an older XC hardtail (Raleigh M80) and was looking for an affordable alternative to going full suspension. I had put a lot of upgrades into my hardtail, so I didn’t want to lose my investment by trading it in for an entirely new bike. Yet, I needed something that would take some of the bumps out of my ride. My local trails are usually riddled with roots, so staying in the saddle and spinning could be challenging. Luckily, the Thudbuster solved most of my fatigue issues. While this seatpost won’t turn your hardtail into a dual-suspension downhill sled, it will take some of the larger impacts out of your ride and give you some more time to sit and spin. The only caveat is that it needs to be adjusted to your body weight using the included elastomers. Overall, a great way to eliminate fatigue and provide a more comfortable riding posture.

I bought this seat post for my girlfriend's new hard tail. She absolutely loves it! I adjusted the elastomer to suit her weight. It was very easy to changes these elastomers since the instructions were very good and they had a nice table to match elastomer color combinations to her weight. This seat post comes with two extra elastomer bushings to make these adjustments if needed. This product has a very clever design and is well constructed. I am very happy that I purchased this suspension seat post for my girlfriend. She was completely stoked when she tried it!

I put one of these on my hardtail after back injury about 15 years ago! It's heavy, but it did soften the bumps a bit. f course, you "shouldn't" be seated while in the rough stuff...
