Front dropout spacer recommendations

Hey everyone:

I recently outfitted my vintage Trek touring bicycle with new Gatorskin tires, because I wanted something thick enough to ride on gravel. Unfortunately, the material is just thick enough so that my front tire hits the top of the fork. I'm trying to fix this issue without returning these tires, so I started looking into dropout spacers. I'm learning that most spacers are made for rear dropouts, so I wondered if anyone knows of a similar product that could fit a front vertical dropout. Thanks!

Traditionally a bit of spoke has been used. I'd be surprised if there is anything you can do to give those tires enough clearance for dirt.

Thanks, I'll give that a try. I only need about a few millimeters of space

Front wheel for riding on gravel. Are you sure this is something that you want to take a chance with doing?

No endorsement of it being safe , but a piece of aluminum tubing slipped over the axle can function,

Basically you bought too large a tire... put an add on craig's list & sell them..

Or , buy a bike to fit the tires you want to run .

Have a machine shop make a couple of shoulder washers out of aluminum or steel. use the wide part of the washer on the outside of the fork. the diameter of the shoulder enough to get the clearance you need and the height just slightly thinner than the dropout. Depending on how much height you need to add, you may need to put a flat on the shoulder to get it to fit in the dropout.

If you're only adding a few mm I don't see why this could not be done safely.

fietsbob has the best hack so far. And the only somewhat safe way to do this. There won’t be much room inside the dropout to get too far.

And then what? Riding in gravel means gravel being tossed around. Gravel will be tossed into that little tiny space between tire and crown. Debris is always an issue off pavement and sometimes an issue on pavement. Or a spoke comes loose or breaks. Or the tire stretches a bit with age.

Gatorskins are a bad solution anyway. Stiff tires don’t work well in the rough. Only way to make them half capable on gravel is to make them very large.

To clarify, I'm not going to be going off road or taking my bike on trails. I bought the thicker tires so that I didn't have to worry as much if I encountered some rougher terrain like construction or in parks around the city, because my 5 year old Specialized tires were worn out.

Ogsarg This seems like a great solution. I'll jury rig it for now, but for a longterm solution this is promising. Thanks!

Buy tires of the correct size. Anything else is a bodge and is asking for trouble.

Ok so I read that 3 mm of space between the tire and the fork is recommended. I only needed about two so I just filed a half circle into the crown and now I doubt there's any risk of rubbing. Kinda redneck of me but we'll see how it goes. Thanks for the help!
