I was looking to buy a Sunpost SP12 NCX seatpost. But then I found out you're supposed to take it apart, degrease it, apply new grease to the coil, and lubricate the joints every 300 miles!! That's too much work for me! LOL

Does anyone do that? I pictured buying this and just using it forever, not having to take it apart and clean it and degrease it every 300 miles. Is that something that's actually done?

Also considering the Thudbuster, which seems a lot better, maintenance-wise. According to the Thudbuster manual, the only maintenance required is:

1. The pivot washers should occasionally be lubricated with a light oil.

2. The skewer and elastomers must be lubricated periodically with grease. Apply grease to the shaft of the skewer and to the
ends of the elastomers.

That seems a lot saner to me! LOL

I'm interested in hearing people's opinions about these products, as well as whether maintenance is actually done, and how often.

Thanks!

I've had a Thudbuster for 5+ (can't remember when I purchased it, maybe 10+) years. I lubricate the "shaft" once every year or two to prevent it from seizing in the seat tube, but that's the only maintenance it's received and it still functions well.

That's great to know. Thanks! Someone in another forum said that he had to replace the things inside his Thudbuster because exposure to sunlight made them hard. Maybe he left his bike outside a lot, I don't know. Have you ever experienced that?

2old

No, but the only time my bike is outside is when I'm riding it and my big fat, well you know the sun don't shine down there.

He's talking about the elastomers, I believe. Changing them is a piece of cake even for the mechanically challenged. As a matter of fact, they make several different hardness's (?) of them to suit your needs, and some people change them out depending on today's ride. They also make the post in a long throw and a short throw post, again, to suit your needs.

I've never personally owned one, but I've seen/talked to dozens of people who have. If you want more feedback, search the tandem forum for them. Lots of people using them there. Every third tandem in captivity has some king of suspension seat post for the stoker, (rear seat rider), as they can't see the bumps coming.

For me, I installed the stiffest elastomer and have never needed to make any changes. Of course, I retained the other elastomers as replacements.

If you haven't tried the Bodyfloat seatpost or I think they call it Kineckt now it is quite nice. I was all in on the Thudbuster because I love Cane Creek and am in fact for full disclosure wearing a CC t-shirt but when I tried the BodyFloat I had to say it was way better and I was intentionally ramming potholes and rough roads (especially since it was the bossman's bike and I wanted to be rough)

Have you ever tried the SP12 NCX? If so, how does the BodyFloat compare with that one?

Have seen them live and in person but haven't ridden one. I wasn't a fan of the design and looks and the weight turned me off quickly. Then again most SR-Suntour doesn't really do much for me as it is a name that meant something and now is mostly known for their lower end OEM spec and getting confused with Madea Corporation. Certainly though the SR design is better than those garbage hiideous telescoping suspension seatposts. I do remember actually seeing one recently and for a second thought Thudbuster and then in the next second was like really bad forgery and then saw the logo and was like oh right they make one of those.

The reason Bodyfloat is so much better is it is less suspension and more about isolation. So instead of moving you up and down the goal is to isolate you from the bumps and vibrations. I am sure other folks can provide much better explanation of it then I but after riding one I fell in love right away and certainly reading reviews they all seem to be rather positive which is good because when I first saw the product I was not really into it. A Kickstarter that I felt looked goofy and weighed a lot more than my beloved Thomson post but now I am a believer and owner. Though I am still not wholly in on the looks but I am a professional and will rise above it.

I am riding on Thudbuster LT long travel and it is pleasure,
they retail for so much for the reason = performance,

The kinekt body float is great on the road with small bumps. At my weight the body float doesn't have much travel though. It's great for isolation from vibrations. I purchased a thudbuster lt for the trails though. I weigh about 220 lbs and the stiffest spring is about bottomed out when I'm sitting on the kinekt. I wish they had a stiffer spring. This one feels too soft.

2old

I have a Body Float (which I don't like as much as my Thudbuster) and it has several combinations of elastomers. Is yours inadequate with the stiffest combination? BTW, seems like the camps are separated on BF & TB since I've met individuals on both sides.

Ky_Rider

It's adequate as long as the road isn't too bad. I have the stiffest springs installed and can easily bottom them out. When I'm pedaling it does a good job of isolating my rear from the road but when I sit straight up and my full weight is on the seat post it's almost bottomed out. Overall I'm pleased with the Kinekt. Maybe I just need to lose a few pounds.
I just installed a Thudbuster on my mtb. I didn't feel like the Kinekt Body Float would have enough travel for off road. I have to do some more testing on the Thudbuster.
Both seat posts are good products imho.

Ky_Rider

I'm kinda leaning towards liking the Thudbuster better as well. It's doesn't appear to have a harsh bottom out like the Kinekt Body Float. Some more testing is needed though.

Put the "thud Glove" on if you expect a lot if Dirt riding its a neoprene cover (of course imprinted with the product Logo)..

both bikes oversize seat tube, machined aluminum sizing shim 27.2mm seat post..

I have used the Satori Animaris and think it is a great value for the money.
