Umm...

although the damage seems harsh, the bike shop tells me that it shouldn't be a problem. But the head mechanic is out today and he's going to look at the bike tomorrow.
I don't think Trek would cover the damage due to accidents but I was surprised how easily it was damageable from just slight falling. Hopefully they'll help me out. I can't say antthing bad for the Trek guys since it started from me having the bike fall. But surely enough surprises me how easily bendable it was from small fall.
I surely hope it all works out.
Umm, considering that most shop mechanics, while good at fixing bikes, are not exactly well versed in the properties of materials, such as aluminum, and or carbon, and or steel, ti, or what not.
I wouldn't ride that bike with the dent like that in the top tube. I actually DO have a background in mechanical engineering with some pretty good experience in materials. That's just me talking though.
2 stories for you.
1. Take a regular aluminum can, of the variety that you get soda in. Make sure there are no dents in it, and that it's empty. Place it on the floor. Stand on it with one foot, placing all of your weight on that one foot. Most likely, the can is going to hold, and be solid. Now, with you still standing on said can, have someone put a small dent in the side of the can by flicking their finger at it. Guess what happens? Can crushes. Now, the frame isn't going to be that drastic, but there is a good chance, especially with that sharp crease in the can, that stress will rise at that point, and the frame could fail. Possibly snapping completely, or bending more. As others have said, this is your life you're riding on, you pretty much want to make sure everything is solid.
2. I had a friend of mine a few years ago that had a dent similar to yours in his top tube. He insisted, even after I told him not to ride it, that he was going to ride the bike. He rode it, it failed, and luckily he got away with about a ton of road rash and a few broken fingers.
So you can ride it, but don't come back here talking about how Trek sucks when the frame breaks on you, and you break your arse on the road.
