I have a 11 year old Novara Verita that is my daily/year round commuter (if you can't tell by the grime). The chainstay recently cracked right where it connects to the dropout and seatstay. The frame is chromoly. My gut says that it probably isn't worth it to get someone to weld this back (heat damage to surrounding joints, alignment, probably other stress issues nearby), but I'm not expert.

Is it worth the cost and effort? Or should I just say it's been a good 15,000 miles and 11 years and sat goodbye?

Thanks in advance.
