Other long mark on carbon frame - should I worry?

[RebornRider]

I noticed this mark yesterday. Today I cleaned the area hoping the mark was just dirt. It's still there. It looks like a crack, but my fingernail doesn't catch on it anywhere. It seems to be perfectly smooth.

Do any of you in the US know a shop that is good at carbon repair?

Have any of you had a similar thing-that-looks-like-a-crack appear on your carbon frame? What did you do about it?

It is not a crack, there is no underlying delamination in the lower carbon layers. It looks to me like a scratch it the protective gel coat layer.

Carry on riding in like you stole it.

PS I have a composite back ground and repair carbon frames from time to time. So I know a thing or 2 about carbon.

Thanks! I agree it looks like a superficial scratch. But it's weird that I can't feel it. I'm going to try some super fine polish that I used to use for detailing cars.

The other thing that's weird about this mark is that it's almost invisible unless the light hits it just right.

Its pretty common when scratching resin layers. It represents as a whitish line. Sometimes deep enough to feel, sometimes not. Try a bit of cut and polish. That might make it less visible.

Off-topic, but what is your oneup pump and fidlock setup? Also what size frame

I have the Oneup 100cc pump with the multitool and tire tire plugging stuff inside.

100cc EDC Pump

I used the Wolf Tooth bottle shifter to mount the pump next to the water bottle.

B-RAD Bottle Shift

I use the 590ml Fidlock bottle because it has a cover over the sipper valve. TBH, there is still a lot of California trail dust all over the top of bottle by the time I want a drink.. But it hasn't made me sick yet!

Try some body-coloured car polish, black of course. Available from all good car spares stores.
