Trek 820 frame, go or no!!!!

Here is a pic of my 2006 Trek 820 Frame. Close-ups of rear dropouts.

Should I use this frame, add front disc brakes, and other quality components to this frame and use it for my MAC 8t conversion kit?

The good, this frame is steel, with a good triangle for my batteries.

The bad?

So what do you say?

I use a Trek 820 frame for both my builds. Works great. I run a rear 2810 9C at 50v 30A with no problems.

When recommending the ideal type of steel frame MTB for a first build, I often cite the Trek 820. Could be the same thing in a giant, specialized, whatever. Nice space for the battery in the tallish frame design.

The drops look a bit tiny, but they are good strong steel, and nothing will interfere with installing a good torque arm. It should have tolerably decent wheels, crank, brakes, etc. So you won't spend $200 upgrading that $100 bike after everything wears out in 500 miles.

Primary concern I see with that frame might be tire width? Big fat stuff 2.3-2.5" might not fit? That would be something folks that already use that frame could answer?
