Bondo.
It can’t be repaired.
You can’t, leave it.
Be aware aluminium is not great when it comes to dents though, be time for a new frame really
No removing of the dent. I would recommend marking the boundaries of the dent with permanent marker – if the dent spreads it is time for a new frame. If the dent starts showing signs of cracks – also time for a new frame.
Aluminum cannot be pulled out or re-bent without substantially increasing the risk of failure or breaking in the process of bending it back. Most commonly seen with derailleur hangers vs old steel frames not needing replaceable hangers.
ETA: you need a new fork – riding that without the lowers connected is almost certainly more dangerous than the dent in the frame. The used market is flooded with bikes these days so it’s probably cheaper to buy another bike either to ride or use for parts to fix this – old Stinkys are cool but ride quality has come a long ways since those days.
Bondo. It won’t ‘remove’ the actual dent, but you can fill it in and paint. Any attempt to pull it out will only exasperate the problem. Highly unlikely it will result in failure as I’ve seen much worse last indefinitely, usually on downtube.
I have a worse dent on my Kona and I’ve been riding it for years with no issue. I’d love to pull the dent but I don’t think it can be done without doing more damage. I do check for cracks periodically.
I had a dent in my frame and I filled it up with this stuff called Bison Kombi kit. Filled it up and sanded it. Felt really stiff afterwards. But it is grey and not really pretty, I repainted the frame as well.

It’s simple. Completely disassemble the frame. Take it to a race fabricator they can cut out a section of tube, fabricate a patch, expertly weld it with gas immersion, smooth the welds, pull all bearings, strip the paint, re heat treat the frame, send to a good bike shop, re bore the BB and head tube, send to a custom painter, re paint, Back to the bike shop for bearing replacement and reassembly and your frame will be cosmetically better than new and all bearings will be on axis. Repair should cost around $3-5k USD (if the fabricator can arsed to touch it), and take a few months. Recommendation: Put a cool sticker on it, and ride
I think we have other issues to discuss if your really riding this thing and taking it off drops… no fork brace, cheap studded tires, square taper hybrid crankset, too much NOS (shit will make you impotent, incontinent and idiotic all at the same time) and that seat / seatpost.
This should be relegated to a bin until you replace those forks, once you do it can be ridden to get around the neighbourhood, but probably shouldn’t be taken mountain biking.
That dent is the last thing you want to be worrying about on that old girl.
there is a way…. but its way to expensive to be practical
you remove the paint, welt on a tab into the dent, pull the tab with a hydraulic tool, remove the tab, the send the frame away to get post-treated again, then re-paint…
it will cost you like 1000$ for this at least…
Watch out, that looks a lot like a fork I snapped in maybe 2003
Filler and hope for the best or wet wheatabix stronger than concrete 🤣
As someone who had the Dee-lux version of that same bike, I wouldn’t sweat the little dent in the frame for now, but I’d be saving up for a newer whip in the future. Those forks on the other hand are a different story and should not be ridden.
And I’ll stop there…wait, what is with that crank? Jfc
U can un dent frames????
