Fork/Tire Clearance Question
I put Marathon 700x38 tires on my touring bike. There was just barely not enough clearance on the front fork so I had to take a Dremel and smooth out a high spot on the fork just above the tire. I now have a whopping 2mm clearance. Rode the bike a while, no rubbing, etc. Any minimal clearances for any reason anyone can think of?

Why not save that big tire to use on the back and put a smaller tire on the front. Grinding on the fork doesn't sound like a good idea to me.

When you pick up a squirrel in your wheel, it'll jam in your fork instead of passing through, likely causing you to fly over your bars.
I think it'll be fine unless you go offroad and start picking up mud and pebbles.

If it's a steel fork there's little risk grinding the bottom of the crown. In fact, that's pretty much standard practice with pursuit frames to get the extremely close clearances ("f@g paper clearance" as the Brits say) required in such races.
But for a touring bike, more clearance is a good thing, not only to allow the occasional piece of gravel to pass under the crown, but also to allow mounting fenders to keep the rider and luggage drier in wet weather.

Rather than saying " out of round," I should have said warped. If you had a little damage while riding, that caused the wheel to warp, even slightly, is it going to rub the fork. Would make a hard ride back home !

hey Im building a recumbent. Im using a BMX fork to hold an, er front wheel, at the rear. Its a sort of Zox 20 copy, front wheel drive bike Im thinking of. The forks on the rear are from a bike that had 18" wheels. But I filed off some of the lower fork crown. The forks are lying flat and the tubings large diameter. So there shouldnt be too much trouble

If its a flying squirrel, we can fly together!
I did think of what you are saying. I had the idea, bordering between genious and stupidity, of mounting a bent toothbrush on the brake bolt with the brushes just at the tire tread level to knock off rocks. And, far more importantly in Seattle, SLUGS! Damn, on the trail last year I hit a veritable slug herd and got coated with slime. Could I mount a salt shaker up there too?
