Dear passers-by and Shimano tech
I recently made a purchase of a secondhand XT m770 crankset(170mm length) from a notable figure in the local biking community .
After the excitement of getting my hands on one faded once I reached home, a closer inspection on the cracks revealed a scar on the driveside crankarm, just above the pedal thread hole .
To illustrate it , I have conjured a rough diagram and pictures exemplifying what I meant:
Diagram(red line represents scar):
Photo of "scar":
The lighting made the scar look shiny
I have also noted the cosmetic nature of the scar:
1. Not jagged
2. No "branches" i.e the alleged crack does not branch out into tiny cracks at each end
3. Thin scar ( my nail cant seem to penetrate into the "abyss" of the crack "
4. Rougly 11mm long
Now I have no real idea on what I am going to do with the cranks...
