Schwinn Ontare

Just picked one up and looking for a set of Suntour Sprint pedals and San Marco Roll seat like originals. And I guess original handlebar plugs. Have a question about the infamous seat post. Seller said he set it tight. After the quarter turn I can turn the post side to side (with effort) but no up or down at all. Anyone have any tips on what I should do?

I would put some light oil at the seat lug, let draw in, then try your back and forth pulling up at the same time.

You are talking about a quill seatpost, right? If so a quarter turn may be enough to get it to turn, but not enough to extract it.

Thanks for the replies!! Yes seat post. I think the quarter turn is all it is supposed to go. I thought the same thing on lubing the post so will see how that goes.

Did you treat it like a quill stem, and confirm that the bolt head dropped down a little, indicating that the wedge is sufficiently loose from the post body?

Why would the bolt only go 1/4 turn? I have no direct experience with these, but that doesn't sound right. You should be able to turn it just like a quill stem bolt.

Hi

Here is the page from the manual. Also my first experience with one. Seems kinda cool but obviously a little more complicated than tightening a bolt.

The good news is the seat post moves!
That's a model I haven't seen before. Very cool.

Yeah, the more common quill seat post has a bolt like a stem bolt. With that cam design, I'm not even sure there's a way to determine if the wedge has released. But it looks like it should be able to turn about 180 degrees, not just 90.

So is the "dot" referenced in the manual visible? What position is it in? Maybe a close-up shot of the cam would be helpful.

I've dealt with one of these seat posts, and only had to turn it 90° from fully tight to fully loose/ready to move. The allen key would not turn further. Looking at the diagram, that adjuster nut at the bottom of the post may be responsible for determining just how much angle one needs to or wants to turn the lever from fully tight to fully loose. You don't want to overdo it on these. Slick design, even if it was failure-prone (depending on who and how someone rode it).

OP you have a MINT Ontare. That's really cool! Very rare, IMO, as it was a one-year model name (and paint combo) before Schwinn switch to the 974, etc frames. How does it ride???

madpogue: The decal or screen is totally gone off mine, same as every other post I have seen a pic of. Must have been fragile. Here is what it would have looked like again from the manual.

Riddle: Thanks! Yes I like it and it was local so no shipping to worry about. Rides beautiful.

Yeah, I blew up your photo after posting, and didn't detect any markings. I wonder if there's any way to detect whether the wedge has indeed released. Just shake the bike a little, listen for a rattle in that part of the tube?

Here is how it stands today. Had to lose the orange bar tape and crappy tires. Been holding the B 17 waiting for the right bike and here it is. This is really a great looking and riding bike. A little torn on the pedals but like the yellow ones so will stick with them.

Ok, I've got a Schwinn Aluminum bike with the quill seatpost too. I does only turn a quarter turn. I wonder if the wedge is seized inside the seatpost?

When you have the seatpost out you can adjust the wedge for tightness or looseness. You try and balance to where it keeps the post from slipping. I wonder if it was installed a bit too tight originally.

By the way, that is a beauty. It should ride as good as it looks. As a die hard steel fan I was impressed with how well my 684 rode. My oldest son has his hands on it now and I don't think I'm getting it back.
