Trek 7000 - bonded frame?
I've just read on Sheldon Brown's site that the Trek 7000 has a bonded alu frame. I have one - should I be worried about taking it down singletrack (or otherwise using it as an MTB/CX bike) for the foreseeable future?

No, just ride it into the ground. I bought a 8000 brand new in '93 and it was pretty much bulletproof. Age isn't going to make it come unbonded.

When I was in college, the Cherry Bike Shop in Lafayette IN had a bonded frame hanging on the wall. The owner had come bombing full speed down a local hill, hit the railroad track at the bottom, and one of the bonds released at the downtube, leaving the top tube to hold the bike together.

I hear of those kinds of failures, but I hear they're pretty rare, too. Probably not a lot of hard data on which ones fail, and how. I've got a couple of old bonded bike frames (Tehnium) but haven't ridden them enough to break them.
I'll let you know when it happens

I really have no experience with these but have cracked my share of aluminium and chromo bikes back in the day doing stupid stuff, most any material can give. Seems rare to have happen but bumps and jumping on a mountain bike would honestly scare me to the point I would probably hold back. Gravel or Road would not concern me much.
