Hello everyone,
last winter I purchased a hardly used Trek multitrack 7200 off ebay. It's got an aluminum frame and a cromoly steel fork.
There is a mysterious "thing" on said steel fork, right at the mounting screw for a potential front rack.
Is this a fatigue crack or something? It is textured, when you run your finger or fingernail across it, you can feel it.
I apologize for the bag image quality. If this isn't sufficient to determine what's going on here, I'll try to submit better ones.
Thank you so much for your help!
