Worked exactly as you instructed, no more squeaky seat post on my e-bike. RJ, you're a genius, many thanks and God bless with one million views more on this post

[@stevenwilliams9997]

You're my favourite bike maintenance guy on KZbin thanks!

[@robertkelly1434]

I've owned my touring bike for 20+ years, did not know that I have a suspension seat post. To my knowledge, the seat has never moved. So now I have yet another project. Thank you for this video. 😏😏😏

[@I_M_Goood]

Thank you for the invitation.... Respects from India 🙏🏻

[@mantroid]

Nice uncommon Fisher. My brother-in-law who is moving cross country just gifted me his 2001 Trek 700 with that same seat! The bike is mint condition since he never rode it, but I wanted to know more about these seats, thank you.

[@patp8191]

Thank you! I just purchased a bike with this suspension. It needed adjustment and now I know how to lube it.

[@garygrinkevich6971]

Very cool to learn about the preload screw on these mine has been bottomed out and the post broke on me yesterday =\ maybe i should replace it with a solid post?

[@ride-thrurider986]

I just added one rubber padding with some super glue and re-assembled the seat-post. No more rattling.

[@outcast566]

You are great! Now I can save money and keep using the one I have. Thanks!

[@mpt12345]

Thanks so much for the video! My seatpost started creaking, and now i know how to fix it! Thank you!

[@JorgeRodriguez-ei2gi]

Say hello from panama city, great & instructive, videos & rebuilt, thanks sharing, keep up the great job, joe.

[@jonnyware9061]

Great tutorial!from the outside it looks like I have the same post. The trouble is the bottom disc with the hex key is rusted and won’t budge! I’ve used a wire brush on it and in the edges, plus put Rust converter on it too. I bent an Allen key trying to remove it! Next method I guess I’ll just have to blow torch the end….

[@billwilhite2190]

I have one on an old Schwinn I just acquired. I'm no longer afraid of it. Thanks.

[@SuperCyril2]

Thanks. Been wanting to do this for awhile now. Great tutorial.

[@namelesske]

Thanks, now i have the courage to modify the preload with a bigger spacer :D

[@skyryder7662]

Buy spacer do you mean that black rubber lead on the bottom of the spring? I bought a used bike and it is missing from the stem, can I get a replacement for that?

[@matthewluke5474]

Just what I was looking for,thank you.

[@scootosan]

I use one of these on my Commuter. Thanks RJ...

[@Dutcharmytent]

Just the information I wanted

[@1simo93521]

Nice. My wife wants me to get her one of these posts. She likes her bike super soft.

[@sonnyboy2026]

Could you measure the exact diameter of a 27.2 mm suspension seat post you have with a caliper? Such as Zoom or XLC. I bought an XLC and it is 27.1 mm instead of 27.2 mm and its wiggly, I would like to know if it is normal. Thanks.

[@Drago0900]

Perfect video as always

[@josephshackleford1]

I bet all of your bikes are so well taken care of.

[@blakepeterson1977]

Very helpful! I just picked up a bike that happens to have that exact model seat post. Problem solved

[@eduardoramon5630]

Good info video thanks

[@majobismusic]

I have this exact seatpost on my Giant bike and my problem is that the top grooves for the seat bracket assembly have stripped. Do you know if the top part (with the black rubber piece that attaches to the seat) is removeable? If so, I'm hoping that I can replace that part instead of having to buy a new seatpost, since the post has low miles on it anyway. Thank you!

[@RJTheBikeGuy]

You probably not going to be able to find any replacement parts. Just replace the unit.

[@skyryder7662]

I have a bike stem with that spacer missing, can you get replacements?

[@RJTheBikeGuy]

???? This is a seatpost. And for spacers, check your local bike shop.

[@RABBlTFTW88]

Can I use normal grease here? What would the problem be if I use normal grease?

[@RJTheBikeGuy]

The grease is used is made for suspensions. You can use what ever you want at your own risk. It may not work as well. It may damage the parts.

[@RABBlTFTW88]

@@RJTheBikeGuy Okay thanks!

[@dandydon6049]

I hated to use normal grease but the grease he recommended cost 13$ for 4 oz. There aren’t many parts to damage. Worked out well for me.

[@11GDR]

What if it has backlash?

[@tonepoet]

I have this seat post, the video is helpful. Time to buy the grease and save money on a new post. Thanks for this!!

[@tmayberry7559]

Never saw that one before thanks so much

[@toyo2502]

Very smart ...thanks so much!!!

[@stevesweney8384]

good video thanks!

[@ivancho5854]

The grease used looks just like standard lithium grease. There are so many "special" products which are just repackaged and cost many times the original product. I see no reason whatsoever to NOT (edited, sorry I wrote the exact opposite of what I meant! 🤦‍♂️) use lithium grease in this application.

[@Mojo32]

I agree wholeheartedly, and that's what I do. I've learned over the years that most products are multipurpose, so at home I deeply stock the basics and I use plenty all around the house, vehicles, toys, etc. without issue.

[@madisonjoyce5964]

Bicycles are interchangeable. I think you may equip a pair of cantilever brakes with a suspension fork having post V-brake mounts.

[@RJTheBikeGuy]

It's possible. But the cantilever brakes need a cable stop, that the V-Brakes don't need. So you would have to mount one somehow.

[@MrGlennhumphreys]

im guessing that grease is thinner-based to avoid clogging and aide faster action?

[@RJTheBikeGuy]

???

[@MrGlennhumphreys]

shyflirt1 slikoleum

[@RJTheBikeGuy]

Slickoleum is a relatively thick sticky, slippery grease that is safe for the plastics found in bike shocks.

[@MrGlennhumphreys]

shyflirt1 ha! right thanks

[@ADRIEL296]

can that grease be used for aluminum seatpost? My bike's frame is aluminum. What should I use?

[@RJTheBikeGuy]

I use marine grease for on the post in the seat tube. You can use anti seize stuff too.

[@ADRIEL296]

thank you

[@redgar6467]

Just what I needed

[@Zalan]

thanks a lot, very good tutorial!

[@sherwin1447]

If the seatpost is new, do I need to lube it?

[@RJTheBikeGuy]

It will usually be lubed in the factory.

[@Lughnerson]

I say yes. At least you know what is in there (before any corrosion) and can be sure it is lubricated properly. You cannot trust what was done before your purchase.

[@sherwin1447]

@@Lughnerson maybe I'll do that. Tnx.

[@artytomparis]

Thanks!!

[@tomlis123]

My suspension seat post turns slightly to the left and right while riding.How do I tighten?The post is tight in the frame and does not turn.It turns below the rubber collar.Thanks

[@RJTheBikeGuy]

Replace it. They wear out. Most of them are not made to last.

[@chuckborden8532]

THX AGAIN...

[@frv6610]

Since the Ebay seller of this (?) seatpost and XLC (manufacturer) aren't replying I will ask same questions here: 1. (Idea for suspended stem for handlebar) Why don't you modify the seatpost XLC SP-10 or any similar one so it can hold a handlebar, why are there no stems with same suspension and similar look? Why does for example the stem XLC ST-T02 not have a suspension (like the seatpost XLC SP-10)? If anybody here knows if this kind of suspended stem in general exists please tell me the model. I have the XLC SP-10 seatpost, 25.4x350mm, and figured it would work with few modifications as a stem too for at least my street comfort bike which has a cruiser handlebar with an angle-adjustable stem which I pointed upward vertically to ground. It would look nice, be cheap, practical to install (no need to change to suspension forks etc) and sufficent for comfort riders (or would it disturb the rider's balance/control too much?). 2. (Suspension-adjustment) Does turning the bottom screw at bottom inside the seatpost pipe adjust suspension hardness or suspension activation treshhold? Is there a way to adjust suspension of this seatpost with this screw or other simple way?

[@RJTheBikeGuy]

1. Why are you asking me? 2. Yes.

[@frv6610]

@@RJTheBikeGuy I don't know who to ask, you are expert so I asked you. I want to buy a stem with same suspension as the seatpost in your video.

[@Lughnerson]

20 years ago some handle bar stems were like hinges and had polymer dampeners. Different colors meant different strengths. I thought it was a good idea, but they are no longer seen anywhere, as far as I know.

[@tomahoks]

No way any seatpost comes off the frame EVER that easy.

[@Subideable]

I always see a margarita in the thumbnail pic 🥴

[@Абоба-з5х]

так что так

[@madisonjoyce5964]

You actually think interchangeability has something to do with bicycles everywhere in the world?

[@RJTheBikeGuy]

Not everything is interchangable. You have different sizes, different threadings, etc. Many bike parts are more interchangeable than they used to be. But some Campagnolo stuff is not compatible with Shimano stuff.
