Well turns out that what I originally thought were just paint cracks are likely frame cracks. Sanded some paint away to reveal that the metal itself appears cracked. As you can see the issue is on both sides of the frame around the upper shock mount bolt, but the non drive side’s worse. Bike is a Canfield One.2. I’ve ridden the bike a decent bit with this issue, as I said I first thought it was just the paint. I’ve taken it down some gnarly stuff with big compressions etc. I think it has grown over time though. What are your thoughts? Safe? Don’t ride? Anyone One.2 owners out there with similar experiences?

Edit: this isn’t caused by a crash. Looks to be a stress crack developed over time.
Please don’t ride that any further. Steel, aluminum, ti and carbon can all break and this aluminum has given you the WARNING.
Sorry OP, life fn sucks
Just give Canfield a call, they almost always pick up the phone during business hours… and sometimes even on the weekend. I’m sure they’ll want you to send them some pics after talking.
I cracked an original Canfield One frame back in like 2011. Called them up and Lance answered the phone, got a new front triangle shipped out to me the same day. Their customer support is awesome.
Wouldn’t send it off a 50fter but you could probably use it for just trail rides till you get a new frame. Could also get some one to weld that jawn up and see what happens 🤷♀️
I don’t like how that cracked along the weld. I don’t like that design. Feels like a flaw to me. (As an armchair Redditor, of course). Looking at a full photo of that bike all of the force from the rear shock goes directly into flexing that part of the frame, which has a big V cut out of it so force will be magnified there and every time it lands from a jump or drop it’s getting cycled. Being alloy it’s got limited cycles before it just fatigue fractures, which it’s done. But cracking along the weld also may be the result of a poor weld.
Don’t know if it could be welded up either. I feel like you’d have to strip the whole frame though so you can heat treat it properly.
Ask r/welding if you like on their opinion of crack appearance and possible repair, as I’m not even close to an expert.
