Hello,

Would appreciate any input on an issue I'm having:

2009 Specialized Allez Comp with Alumninum frame and carbon rear triangle with concern for corrosion. I ride 4 seasons in the Northeast, with regular care and maintenance, racking up 25k+ miles. Crashed twice in local races without any apparent damage. Over the past 6 months, I have noticed bubbling and cracking of the paint due what I assume is corrosion at the joint between the aluminum and carbon rear triangle on the seat stay, 2" below the seat cluster. It's progressed, and is now circumferential, focused at this 1" thick spot. My LBS was not too concerned, thought it was superficial. Pics below.

Should I do anything further to work it up? Is it reasonable to keep riding?

Thanks!
