Bianchi superleggera help !
Hello, just bought this bike and noticed a crack on the seat tube lug, I was wondering if this could be fixed and if the frame would then be safe to ride. I was thinking of drilling a hole to stop the crack and then fill it with mastic epoxy.
I am not terribly thrilled by this purchased and paid the $100 mainly for the rear derailleur and shifters (is that a first gen c-record?). Oh and is this what you guys call a death stem? Just thought it would be good to know !
Thanks a lot for any help and feel free to comment !

I've never seen a lug crack. I would take the seatpost out and have a closer look (although you've probably already done that). Are you sure the lug has cracked?
If it was my frame I'd have a go at brazing it. If it gives way what could happen? If the top of the lug does give way perhaps the seatpost could slip down the seat tube. the seatpost is quite a safe distance into the seat tube. I don't think the seat, seatpost and you are going to be thrown backwards off the bike.
It's up to you but I'd try to repair it (if it is cracked).

A superleggera is a fine bicycle, well worth saving. I have never heard of anyone epoxying a crack back together; but it might work. The challenge is to get the crack propagation to cease. it is normal, I believe, to drill a small hole at each end of the crack...

I wonder whether someone in years past tried to force an oversized seatpost into that frame, or whether a tall and heavy rider just put too much internal torque on the lug. The more seatpost I could maintain inside the seat tube, the less I would worry about safety in case of a lug failure, but I would monitor that crack after every ride.

Have a frame builder take a look at it. From the fuzzy picture I can't tell if that is a crack or a scratch that has rusted.

thanks for your help! I looked at the other side of the frame and saw that the crack is much longer than I thought.I dont see any defect inside the seat tube. I will probably strip the paint in around the crack to see how bad it is, I think its dead ...

Yep - it does look pretty serious - I wouldn't ride it either. But I would take it to a frame builder and see if a brazing job would repair it. It is a lovely frame - I can understand your disappointment.

Yeah , It would have been a great frame to put the 9 speed dura ace group I have , I was thinking of having it powder coated red and paint the headtube white , I guess Ill stick with the Limongi frame I have. I'll keep the fork but if someone is near montreal Quebec and wants the frame ,once I am done removing the parts, I will probably give it away.
