Is this chainstay cracked?

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

Could just be the edge of some tape used as a paint protector on the chainstay.

It's nearly impossible to tell from the photo. Especially since at least one of the lines appears to be the edge of a clear sticker.

It doesn't look cracked - way too straight to be a crack. Looks like it's part of the design.

I would try stomping on the chainstay really hard and see if it sheers off there.

IDK, maybe your heel is going to rub a hole through though, Must have duck feet like me. I use a lizardskin velcroed chainstay protector on mine.


To me it looks like the edge of a clear plastic protector.

I think that it's a protective sticker, too, but I'm wondering why it's showing silver under the flecked paint if this is a crabon bike. Do they do a primer coat of some kind?

I think it's a primer. It looks more white than silver. I did some googling and the Z5 is a crabon bike...

Yeah but why is the paint gone? Is this particular Z5 a crashed crabon bike? Crack or no crack that's a do-not-buy.

I know what you guys are looking at, the horizontal line, but I'm looking at the vertical line about an inch or less to the left of the big ring. That looks like a crack to me, at least in this photo.

Yeah, the vertical line is just the edge of the sticker.

The vertical line looks like the edge of a clear plastic sticker. Much like you can see in this picture:

Echo the above that it looks like a sticker, or rather, the clean line on the top half of the tube looks like a sticker, the less distinct line below looks like muck run-off that was influenced by the edge of the sticker.

There is a bit of rash on the rear derailleur and the driveside shifter so it clearly suffered some sort of incident. The bike was donated to a school that is attempting to sell it. Apparently the donor did not clarify what happened.
