Fender clearance... a solution.
This is usually a problem with road bikes when you try and fit wider tires into a frame that was designed for skinny little slicks and when you add studs the clearance issue can become even more problematic.
Solution...
Cut the fender right in front of the brake mount and fabricate an extension for the nose piece so that the fender does not pass between the fork blades.
I used some pre-drilled steel flat bar that cost all of 40 cents to fabricate the mount.

Are those screws poking out of your tread blocks? If so, and you installed them from the inside out, how to you protect your tubes from the screw heads? And... how long did it take you to do it?

That is a self studded tyre... the screws are mounted from the inside and a second tube was used as a liner.
The traction on ice is awesome and they do not affect straight line riding so the bike's speed on dry roads is still excellent.
I've done so many of these it only takes me about 45 minutes to an hour to stud a tyre and the cost is about $4.00.

Well done.
Interesting frame. I remember seeing Steve Bauer frames back in the 80's / early 90's..

I've done the self-studded tire thing, too. Used roofing nails and sealed/protected the heads with silicone caulking. Took some end-nipper pliers and cut them down to size to clear the frame w/o scratching. They worked awesome on hardpack snow-ice.

I won't fork out money for commercially made studded tyres... I just retired one of my first studded tyres and it has seen over 20,000 km of winter riding.
I built up these Schwalbes last year for my hybrid but my friend needed a set of tyres for his winter bike (the bike pictured here) so I will just build another set.
I am thinking my hybrid has the frame clearance to run a 29'r sized tyre so may try that...

The bolts hold the fender to the mounting plate.
It is hard to tell tell that there is anything different about this fender when you look at the bike and I was thinking that plate might be a nice mount for a light as well.
My friend was very pleased with his new winter bike... I delivered it tonight and was tipped with some wonderful single malt scotch.

Look really closely at the images and you will see where the mount comes from the rear of the brake, passes under it, and then rises to meet the fender.

Ahh I see. For the front fender -- I also see that the mount is attached from behind the front fork. I have my front fender mounted in front of the fork, between the fork and the brake caliper. I wanted to mount mine behind the fork, but my fender won't fit. I was wondering if there was a work-around for this. According to Sheldon Brown's site, I think he describes my problem perfectly.
"Traditional fender hardware has not changed since the days of exposed nuts holding brake calipers to the frame/fork. However, most newer caliper brakes use "recessed mounting." This has required mounting the tab on the front of the fork, which reduces clearance under the fork crown, and also rotates the front fender forward so it provides less protection to your feet (and your drivetrain.)" (from https://www.sheldonbrown.com/harris/fenders.html )
Is there a way for me to mount the front fender behind the fork without ordering the part since I have a "recessed mount"?

This fork also has a recessed mount and the mounting tab for the rear part of the fender had to be dremelled just a little to make it big enough for the brake nut.

I had done the same thing for my old lugged steel Allez. Fab'd during lunch time while in Tacoma Wa.. I lucked out because I work in a sheet metal shop. Hit the scrap bin and go to town.
Great job. Always think outside the box.

Thanks for posting the pics and stuff, but - thinking about it, I just feel like "if I had the clearance between the tire and the brake to pass a thin piece of metal through, wouldn't it be easier to just pass a fender through there?
Or did you have a different purpose, like needing to put a fender on a bike that can fit it but doesn't have fender mounts?
I know on my cheaper road bike that I've been entertaining putting fenders on, the brake has slightly *less* clearance than the fork. I think it's designed this way deliberately so that if you put to large of a tire on the carbon fiber fork won't get damaged. But whatever the reason, room between the brake and the tire is the biggest obstacle to fenders...
(And before anyone suggests it, I already have the clip-on kind, just been wondering about fuller coverage fenders)
