Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

What size?

Thinking about going to look at this for my son, but they(sellers) aren't sure about sizing, and guessed at a 54 or 56 cm frame. My son would need a 58 or 60cm, so I am wondering if you think its worth the 35 minute drive to look, or is it definitely a 56 or smaller.

That doesn't look like a 54 to me. I'd guess at least a 56, maybe a 58.

Can you ask them to measure it?

Looking at it I’d guess that it’s a 58cm frameset.

It looks 58ish. It'd certainly be worth a half hour in the car to confirm.
A late 90s Columbus Thron OS tube frame with dropped seat stay?...jut neat and totally worth a peek.
OS Thron wasn't the lightest, but with the butting, it should be a solid and reliable frame with which to build off of.

It looks much larger than my 54 and 56cm frames. However, if it's 650c wheels then it might be a 56. Maybe the seller could share with you what the tire size is if they don't want to measure the frame size.

I think that is a 58-60cm.

Edit: I'm going to go out on a limb and say 60cm. Let us know what it ends up being.

Agree with others that that is at least a 58, but probably a 60.

Doesn't you son want something with less dated components? Of course if it's only $75 or so it'll be a nice bike to learn on.

The 1x crank is odd, but it otherwise looks like a modern Claris shifting drivetrain and the bike really isn't outdated compared to entry level road bikes. For $60 you could have a double crank and FD of equal level.

Not too modern. The right STI looks like one of those that has the cable coming in the top of the hood. The 1x front might be good for the person selling it or maybe they found out it wasn't and that is why they are selling it.

While I don't have an issue for 1x when it's used correctly, on an older road bike with old components, it really limits the terrain you can ride because an old road bike and even more recent road bikes won't be able to handle the range of gears needed for rolling hills. At least not unless the entire groupset is upgraded front and back.

The purpose of my comment though was more because a dad or husband that is too involved in the type of bike to purchase for child or spouse probably is going to get a bike that won't be used much.

Yes, its an externally routed shift cable. This tech works perfectly fine and is on gobs of bikes that are ridden every year. There is no performance improvement now that the cable is routed under tape, its just cosmetic.
The bike in question is has an 8sp STI drivetrain- thats modern since bikes are still sold with 8sp claris drivetrains. Its entry level, but modern.

That 1x is a smaller ring so your concern about hills may not apply, but I agree in general that 1x is more limiting which is why I mentioned $60 will convert the bike to a 2x setup.

Assuming the price makes sense, I wouldn't hesitate to buy this for my kid if it fit. Its a solid frameset and modern entry level drivetrain.

As a caution. If it is a bodge 1X system there may be issues with the chain staying on. Normally a 1X would have a wide/narrow chainwheel and a clutch rear derailleur otherwise when on a bumpy road it may have a tendency to toss the chain.
