Hi all.
Decided to brave the weather today and go out for a spin. Slow steep uphill and a nice long (muddy, wet, windy) DH for desert. All went according to plan except for one little? ding.

I paused at the top for a while to take in the view, I perched my bike against a rock, a 12' one as it happens, but to my dismay I turned to see my bike had fallen over. It only fell over on its own axis but when I inspected there was a large 'gash' taken out of the top tube (see attachment) due to the rock protrusion on the ground. It was granite by the look of it!. The marks are each about 1cm long and roughly .25mm deep at the worst point.

It's not a question of vanity, I can live with the asthetic end of it, but I would like some opinions on wheather the frame could be compromised as a result. It's a TREK 6000 Alpha custom aluminium frame. I hope I'm just being over cautious, thanks for reading.

Cheers
