mecheng89 Posted February 25, 2023 Share Hello Hubbers! I've had the misfortune of a few dropped chains, causing scuff marks on the crank as shown in the photo. 2 questions- can I be polished or repaired to as new condition? And, if there a protective aftermarket film I can apply? Thanks! Link to comment Share on other sites More sharing options...

splat Posted February 25, 2023 Share Isn't that anodising ? I don't think that can be polished out or touched up. Would like to know as also have some chain scratches on my cranks Link to comment Share on other sites More sharing options...
DieselnDust Posted February 25, 2023 Share Those scratches are now adding character as the only wa y to repair those is via painting. The alternative is to polish the crank and that will remove the entire coating . It will then have to be polished regularly. Link to comment Share on other sites More sharing options...
swingTOpeddle Posted February 25, 2023 Share Maybe give Cerakote a go and let us know how it works on bicycle parts? I’ve not seen on here anybody doing this yet. mecheng89 1 Link to comment Share on other sites More sharing options...
Eugene Posted February 25, 2023 Share You are like me, I hate any type of scratch on my bike. After Googling Cerakote, that seems to be your answer. Would love to know the pricing. Things like this tend to be expensive. I am pretty sure that somebody handy with spray paint, could fix that too. mecheng89 1 Link to comment Share on other sites More sharing options...

Ceracote will require you to cover the branding of you want to keep it or lose it and make the crank look like a non series crank. warranty void obviously Edited February 26, 2023 by DieselnDust mecheng89 and dasilvarsa 1 1 Link to comment Share on other sites More sharing options...

BuffsVintageBikes Posted February 27, 2023 Share I did this for a friend some time back. That's cerakotes silky black. The design was laser engraved and painted. Total cost around the R1500.

andreas17777 Posted February 27, 2023 Share My crank looks the same, super annoyed as my campag cranks and sram did not have this issue. Link to comment Share on other sites More sharing options...

I was under the impression Di2 sorts all this high low tension screw guessing game out for you. A bike shop told me nope, you still have to go into the app (there's an app for that), and pay around with the gaps between the chain and the mech to get it just right.
