For all you frame builders out there, a question. I have a 92 RB-T that has been both my winter commute bike (with lights and fenders) and my summer mountain bike (with cyclocross tires and suspension stem) for the past 4 years.
Today, I noticed that the lower headset bearing race was loose inthe frame. It was an aluminium Specialized set and I thought the perhaps thesoft alloy had worn or become ovalized from the stress of off road riding. I substitued a steel Specialized headsetthat I had around and thelower bearing cup was a better fit but it still went into the frame withpressure from my hand alone. It was a difficult push but it still did notneed a press to install. I suspect now that maybe my lower lug has become ovalized or just gotten larger than spec. due to age and a hard life.
My question:
Is there a way to repair this short of removing the lower lug with a torch and brazing a new one onto the frame. Shims? Epoxy? External set screws?
I'm open for suggestions
Thanks in advance,
