How To Repair Fork Stanchion Scratch With Epoxy Resin

GMBN Tech

73,404 views

Crashing on your bike sucks! Especially if you are unlucky enough to scratch your fork, air shock or dropper seat-post stanchion tube. Scratches pass through the seals and can damage them, or can act as a little pocket to collect dirt and grime which can make it's way into the internals. So it's best to repair it if possible.

Note: Repairing stanchion tubes is highly delicate work, great care should be taken, and should only be carried out with specific tools and materials.

I’d probably tape around the epoxy before sanding so I didn’t sand unwanted areas

@yannickbulliard44 2 years ago

The grit size is incorrect in the video. Do not use 150, this would likely ruin the stanchion even more, but 1,500. You can guess in the video that one zero is missing

@Chris-wf4ws 3 years ago

Why not showing us the result you’ve made? Pretty weird.

@celynjones4958 3 years ago

Good job but why no close up on the repair when finished? Kind of missed the whole point. Show and tell.

@maxime99991 3 years ago

Way too much epoxy resin here... You should use a needle or a toothpick to only apply small amount of resin on the scratches. You would save a huge amount of sanding time.
In this kit, they also provide polishing paste that helps to get a very nice and smooth finish. I've used it on my Sid and the result is perfect.

I used a Stanley blade to remove any burrs then car body filler and sanded It down with 2000 grit wet and dry. Been fine for 12 months now

@fairlyfunctional2236 3 years ago

nice. i didn't know there was a fix for scratched stanchions. thanks, anna.

@reefbloke 3 years ago

Now I’ve not done this myself but de-nibbing the resin with a new sharp razor blade( not a Stanley blade) by holding the blade flat to the stantion and slowly de-nibbing the resin without digging into the station should give a finish that requires very little to no sanding . Maybe someone should try this on an older pair of forks as it’s a method I’ve used for years for de-nibbing car paint runs or stone chip touch ups

@20CycleMonger 3 years ago

Good explanation, but No close up of the result?
🤔

@TheJackoelliott 3 years ago

I've always used hard beeswax melted in to scratches even deep ones .
Easy to level out . Doesn't effect the seals and easily replaceable.

@KatoTheMaster 3 years ago

For the Kashima Coating just buy a gold paint pen "UNI Paint Marker is a good match" and add some of it to the mix of the epoxy resin.

@chaselilly8541 3 years ago

I'm a mountain biker and a knife maker. The knife making part gives me epoxy experience and I knew as soon as you said epoxy it would work. But not like that. No close ups of the results since I assume you Aldo know you put too much resin. I know from personal experience that much resin take an hour to sand down carefully. I assume you were not careful scratched it up and did not want to show it.

@SR-gt350 3 years ago

That can't be 150 grit sandpaper. Unless it's metric for 1500 grit. I'm thinking 1500 to start and go up to 2000, then 2500

@marcstucki 3 years ago

I have two forks with scratches like that but I'm worried that I would do more damage when trying to fix them.

@grayembo 3 years ago

Sand paper glued or fixed to a plexiglass block would be less likely to bend or fold past the epoxy and scratch the tube. That foam block would be difficult for accuracy.
