I finally completed my first road bike build, which I've made a lot of mistakes on and learned a lot - a Specialized Epic Allez early 90s lugged carbon frame. I had been tweaking and testing it before taking it out for a full day, and felt a bump and a wobble. Rode gently home and discovered that the chainstays had pulled right off their lugs at the BB! They had been pressed back against the BB by compression forces and the rear derailleur cable and were wedged against the BB, off their lugs.
I think the failure may have been caused by my fitting a 130mm wheel into the 126mm dropouts, putting some force on those joints.
Unfortunately I didn't photograph the original failure and have since been able to prise them away and back onto their lugs. I will take a picture of the affected area tonight.
The question: Has anyone ever had any luck repairing carbon/alu bonds, or is it wall art? Thanks for any input.
