Chipped chainstay repair

Shav

Hi,

I installed a new Hollowgram Si Crankset on my Cannondale Supersix Evo. I've had a few occasions when shifting to the smaller chainring that the chain becomes snagged on the chainstay and the result can be seen here: https://1drv.ms/i/s!AnxxeTmvKEGui_E-pBci4xRD8prILA

The epoxy has been chipped off but looks like the carbon underneath is fine.

Can anyone recommend how to repair? Did a quick Google search and seen nail varnish and Araldite mentioned.

Any ideas greatly appreciated.

Nail varnish has always worked for me. I have one bike where a nail varnish repair over a chip is still holding up fine about 15 years later.

Just make sure you first clean the area you're patching - don't use acetone as it can attack both paint and epoxy, shellite or equivalent will do the job without damaging the surrounding paint or the C-F.

Yup - nail varnish will do nicely.

I'd be less concerned with doing my nails and more concerned with working out why front shifting keeps dropping the chain...

Contact Rob Hayles on twitter. He fixes carbon fibre frames. ( i.e. Former Olympic track cyclist )

And for that superficial chip he'll say nail varnish or touch up paint from Halfords.
