I noticed this crack in the seat of my Schwinn paramount 974 from the 90s. My local shop said it's safe to ride since the post goes down like 9 inches further Into the frame and it's already at its lowest possible setting. I'd just like a second opinion. I have no idea how long the crack has been there, and the seat has no issues currently. I just wanna finish the season off with this bike and upgrade next year.

Forgot to mention, the crack doesn’t extend any further than what is shown in the picture.
Yeah f that. I ain’t riding with a cracked seatpost.
It is just a seatpost (they are cheap) replace it. All you need to know is the diameter. You could look used for something vintage or just slap a modern one of the same diameter in.
Replace that. I know some guy who got seriously injured from a catastrophic seat post failure, and it was genuinely horrifying.
Is replacing a cracked seat post considered an upgrade tho? Imagine that breaking and ending up in your colon.
Well, that is a post-post.
That seat post is a special deal just used in those aluminum Schwinns in the ‘80’s. Pretty hard to find. I would not ride it in that condition.
If your local shop ACTUALLY told you to ride that, they’re absolutely dumb.
That’s a hard nope
Catastrophic? Not unless it made you crash or exploded. But it’s definitely fukt and needs replaced
if I’m not mistaken, you are riding a 1988+/- Schwinn aluminum. You can get by with a metal pipe clamp, bit it sucks. Occasionally you can find one on eBay. Or find an entire bike.
This style is hard to find. There are instructions online how to make one.
The instructions i got was, “make it tight but not herculean tight or it will crack.” when i bought it.
Good luck.

Not yet. Right now it is just a failure. If you keep riding it will become a catastrophic failure
Old seat posts crack like that sometimes. I just replaced mine on my 1989 Fuji Ace. It is dangerous and it doesn’t matter that the seat post extends deeper into the frame. The cast part that clamps the seat can break off and then you’ll get stabbed with sharp metal at the top of the tube.
If you’re really in love with this seat post, you can try laying the bike down with the crack on top and try repeatedly placing a run of Loctite Super Bearing Retainer. Then leave it in this position for 24hrs and test it out for movement in the crack. I did this with a cracked seat bar in my aluminium frame where the seat post went in and I’ve been riding it for over a year now without any further cracking.
Yes, it’s a failure. I would not ride on this. If it fails you could get jabbed in the ass by something sharp. Since you’re planning on upgrading anyway, no better time than the present.
Have someone weld it for you or weld it yourself if you know how to. Looks like a short work with a TIG machine.
BIG ass hose clamp…. Chefs kiss.
