I'm looking to build a new bike for touring (and getting groceries)
I am looking at this '93 Diamondback Sorrento tomorrow. It's $35 and seems to be in good condition. Here's what I know:
– True Temper Cro-Mo Main Tubes
– Cro-Mo Fork
– 26" rims
– 430mm chain stays
– Shimano Altus C10 groupset
– seat stay mounting holes
– cantilevers brakes
I'm planning to do a drop bar conversion with bar end friction shifters (I can't stand fussing around with indexed systems tbh). I also have a Shimano STX groupset off a Trek 750 that's a bit nicer than the Altus. New seat, new tires, new pedals, overhaul everything, basically.
In other words, I am buying a frame and rims lol. I'm just asking if this would make for a good touring setup because I'm a bit concerned about chainstay length. From what I can tell, 430mm is standard for early 90s MTBs. However, my last touring setup, a 1985 Fuji DelRey had 435mm chainstays, albeit a shorter overall wheelbase. This was of course due to road bike geometry and 27" wheels. And with the Fuji, I was getting front end wobble when I only had the rear loaded with panniers. These days I just get groceries on that bike, and I still get wobble when I buy a lot of heavy things. I just want something with cushy tires and more stability.
And before you ask: yes I'm tall, the frame is my size, if not a tiny bit smaller than I prefer.

Not the best but not the worst.Â
You might want more hand positions and holes for a front rack. Check if tires you like are available in 26.Â
It’s cheap, not terrible, and it’s your size so go for it.  In five years you can upgrade.Â
Looks fun to ride – unsure as for longer days in the saddle but it’s certainly possible.
Basically if it’s mechanically sound/you can keep it going and you enjoy riding it, anything is viable for a tour. Ride what makes you happy.
I think so. I just watched a documentary about these bikes called “klunkers” and this reminds me of one of those. It’s not derogatory.
Ask yourself:
Would I feel comfortable riding this bike for many hours at a time, multiple days in a row?
Yes. My first touring bike was from that era and with the same MTB geometry and frame material – should be fine for a starter tour bike, especially with the upgraded groupset! Check that the wheels are in at least good to better shape – true and minimal/no rust on the spokes/nipples. Replace consumables and pedals, put some slicks and a rear rack on it, and off you go! At that price, what do you have to lose? And as mentioned when you outgrow it, you’ll know more about what you want for a newer bike with modern geometry and components. Go for it!
