Did I save my frame just in time? (Reasons I hate aluminum pt. 2)

Been riding with an old seatpost for months on my aluminum bike and noticed that It occasionally slipped unless really, really tightened. Then recently I found out that the seatpost is actually too narrow for my seat tube by a very tiny margin! (dun dun dun)

Swiftly, I removed the seatpost and made plans to buy a correct size one.

Now, there's no visible cracking or stress marks on the seat tube.
But the seatpost has been really clamped down hard and for a considerable amount of time and since aluminum is the drama queen of metals, I'm now paranoid that I may be riding a potential death trap.

Would continuing to ride the bike with a properly fitting seatpost be risky or do you think I dodged a bullet just in time? IK the final verdict is mine but I feel a lot better getting a second opinion on these things from people who have a lot more experience with bicycles of the mountain variety 馃槄馃槄

useless anecdotal experience here...I did this (overtightened the seat clamp due to too small of a seatpost) with an aluminum frame back in the day for quite a while. Then, I wised up and cut a shim from a beer can and ran it that way for a few years. That frame never broke, I just ended up getting another bike at some point...

if you inspect it well, pre-ride, mid-ride, post-ride, every time, you can figure it out before sudden death

You hate a particular material because you put the wrong sized thing in it?

This is incredibly strange.

It's fine. You'll be ok, just keep an eye out but pretty common for people to do to their seatpost.

And better it's aluminum than carbon ... Probably would've cracked carbon.

If it's not cracked most likely you're OK. I'd check it after every ride for a few weeks just to be safe but most likely if it was going to fail it would have already.

To me, it鈥檚 a lot less to do with 鈥渨rong size鈥 and the insane amount of possible sizes.

pick a fucking size and be done with it already.

I'm in full agreement with this...just look at this pile of extra seatposts of varying sizes that I've acquired over the years.

it's less that i hate the material itself and more that i hate working WITH it

I have a carbon bike ... The advantages are minimal.

You didn't answer my question. Which frame is this? Make, manufacturer? Not really a hard question.
Frame materials are like wimmin.
They're all different, they each have their own unique advantages and disadvantages and you have to learn how to handle each one specifically in order to maximize its potential.
