- In this video we take the SDG Tellis seatpost that has been living on my hardtail for about 2 years now and give it a rebuild. New seals and bushings to keep it moving smooth and wobble free.
The design used is similar to a few others on the market. This guide may help you be able to rebuild your post if it is a sealed cartridge design like this one is.

You're a lifesaver; I'm rebuilding my wife's dropper & never would have figured out the bottom bushing without your help! 🍻
Glad to have helped. These types of videos have helped me in the past. Just trying to pay it forward.
@@WattOnWheels I wish I could give you an extra like. I very much appreciate this attitude.
@@mydearriley I really appreciate it. Thank you.
Big thanks for the video 👍 really helpful and hopefully my service kit arrives in post tomorrow so that I can re-build mine 👍👍👍👍
Awesome. Glad I could help. Take your time and don't force anything and it will all go smooth.
Excelent tutorial. By the way this SDG are the same as Cannondale DownLow droppers. So exactly same process and spares. Already checked cause i've serviced both of them.
Aye! Thank you! Good to know about the C-Dale droppers. Hopefully this tip helps even more people out.
i have one of these posts and the saddle rocks a fair bit side to side,new keyways sort that out or need the whole bushing kit?
The keyways will fix that. But since you already have the post taken apart and the full bushing kit isn't that much more, it would make sense to do a full service and replace them all. Either way you can't go wrong.
Quick question - at the 9:10 mark, you were showing the black bushing at the bottom with the two teeth that align with the keys. You were holding it with the outdents for the two teeth on this black bushing facing up, but it looks like you quickly rotated it so those teeth pointed down before you installed it on the dropper. Should the two teeth on the black bushing point up or down (towards the saddle or away from the saddle)?
The two tabs will face down. There is not enough room for the anti rotational slide bushings if the small tabs face upwards.
@@WattOnWheels thank you! Great video. I’ve bookmarked it for next year’s service!
Hi there great in detail video, what are your views on leaving the seat post in the bike to do this rebuild as there seems no reason to remove it. Unless I’m missing the obvious. Just a thought!
Leaving the seatpost in the bike definitely can be an option if you are just doing the basic service. But, since you will be in "maintenance mode" it is a good time to check your cables and the actuator while you are already working.
Good question, thank you.
Have you tried swapping out the cartridge on this seatpost? I have the same post and it seems there is no way around buying the SDG locknut tool.
I believe the tool comes with a cartridge if you get it from SDG. Without their tool, a person could make a socket work by modifying it but for the added effort, it's probably easier to get the tool. If there is a shop near you,maybe call and see if they have one already.
Hi, what is the seatpost stroke ? 150 or 170mm ?
This particular post is a 150MM. This post can be purchased in 100, 125, 150, and 170.
great video man! and you're an on one rider too!!! subscribed to your channel keep up the good work
Ya man! that On One has treated me well. My friend turned me on to them long ago when he had a kick ass On One 456 Summer. I just subbed back for ya
Great video! Do you have a link to the rebuild kit?
I recommend getting it through your local bike shop. But, if that's not an option here is the link to all service parts from the SDG Website sdgcomponents.com/collections/parts
@@WattOnWheels thank you! I'll definitely check and see if I can find it locally. Much appreciated!
Was yours knocking and making a bunch of noise? Do you think this would fix it?
No, not a knocking noise. Just a slight amount of side to side rotational play in the seat. Is yours making a noise when knocking up and down or side to side?
@@WattOnWheels maybe both? Its bren pretty noisy when I'm off the saddle going I er bumps.
Can you take a video of it and send it to my email?
@@BigVanLittleAdventures the way to fix that is to extend your seat post all the way and tighten the oil cartridge lock screw which is located under the rear saddle bolt.
Great vid dude
Thanks man! I like to take stuff apart. I can't help myself.
I think that grease you have used is way to thick and sticky, the dropper will not work good when temps drop, also some oils and grease can swell rubbers over time. I believe the correct grease would be suspension grease, does not need to be waterproof because the wiper seal is supposed to keep water out for a certain amount of time (service intervals). Just saying
For the most part you are correct. I do have Buzzy's Grease that I use for internal seals. But since this was a sealed cartridge, the grease is mostly being used for the rotational key bushings and main wiper seal thicker "standard" grease works very well.
Can you get a no flat insert for a 26 x 4 fat tires?
Tannus Armour does make a foam insert for 26 in fat tires. I have a separate videos showing them off if you would like to take a look.
