I just bought an old 1983 Trek 400 for $100. I know this price is a little high but the bike is in great condition and all the hubs/bearings etc are very smooth and the bike is totally functional.

I don't know anything about the 2001 Manganese Alloy. I know its old steel and its not TOO heavy but its their entry level bike from 30 years ago. Will it hold up to some sport touring ? (ie loaded rear rack w/ camping gear)?

I'm wanting to run it as a commuter/bar bike/ beater/ winter sacrifice with the ability to do some light tours comfortably.

It might inherit my gf's 7 speed rsx double sti drivetrain as i upgrade her allez but I'm considering building it up as a triple.

First things first. New wheels.
If i have a set of 700x23 rims what range of tire sizes will that safely accommodate?

Can i run as high as 28? would you guys recommend 25s?

SKS fenders 700 x 35c?

Tire recommendations?

how about these wheels?

I don't know anything about mountain/touring wheelsets. i've just heard the xt hubs and double butted spokes are pretty bomb proof.

Lastly, in my long line of questions.

Brakes are old single pivot with the nut (not recessed like later 80's single pivot). Can i throw on some new long reach dual pivot and just put the nut on to secure it? or am i stuck using ancient brakes. The bike doesn't have braze on for Cantilever.

Thanks!
