mounting fenders on bike with cantilever brakes
Lee
winter trainer.
I'm going to want to mount SKS fenders on this bike, and it just occurred to
me that I won't have a rear brake bridge (or drilled front fork crown).
I can have eyelets put on the dropouts...what else do I need to do to mount
the fenders? I'd prefer not to create a ziptie monster!

If you can have eyelets added, then why not a bridge in back and a
drilled crown? You can have them done with plenty of clearance, and I
think those are really the correct places to mount fenders. Without
'em, you don't have much choice but zip ties...

Thanks Andy,
I took a look at the SKS fenders...looks like they don't mount against the
rear brake bridge anyway, just on the dropout and at the bottom of the seat
tube.
On the front, I'll either need a drilled fork crown or maybe use an SKS
steerer tube mount.

won't last long, like maybe a few months if you're lucky.
There's an insert-slider piece that comes with the SKS fenders (and nearly
every other full-wrap fenders) that attaches to the bridge.
I agree with Andy, definitely have a brake-bridge added. It's nice to have
if you want to install a rack for commuting too.

You can use what the aircraft people call Audel clamps and what bike people
call P clamps-they're round with ears for a small bolt or machine screw.
Blackburn makes them in cycling sizes. The fork crown takes a bit of
imagination. Imagine a piece of metal with a tapped hole in one side and a slot
in the middle. It fits up inside the steerer with the brake bolt going through
the slot and the tapped hole on the underside. You put a hole in the fender and
a machine screw goes theough the hole into the tapped hole. Arrange the
distances between the slot and the tapped hole so that as the machime screw
tightens the fender against the bottom of the crown it also tightens against
the brake bolt. Instant fender mount without a drilled hole. Many French bikes
have this type of fender mount. This may be similar to the "SKS mount", I don't
know.Or, just drill a hole in the crown.

I think I'll ask Toby to add a rear brake bridge and drill the fork crown.
He's building the frame in the next week or so, so I'm glad I sorted this
out now!

Toby, cyclecross... must be Toby Stanton -- great guy, great frame maker!

Yep.
I still thank my luck stars that I ended up at his shop. I had bought an old
Brian Rourke cyclocross bike off ebay and took the frame to Toby for
painting. I had done some shopping around, and almost ended up just shipping
the thing off to get painted, but ended up at Toby's. His shop isn't far
from me, and his paint prices are quite reasonable.
The Rourke is the same size as my road bike, and Toby indicated that I
really wanted a frame a cm or two smaller for cyclocross. Then he pointed
out that the front fork wouldn't accomodate a really wide tire and that it
was pretty heavy...
So there I was. Impulse buy. Just happened to be in the hands of one of the
most knowledgeable cyclocross frame builders around!
I had a feeling he knew what he was talking about :) but didn't really get
it until I got home later and did a websearch on Hot Tubes!
Can't wait for my new frame...hope to pick it up just in time for my 43rd
birthday and a 'cross clinic with Mark McCormick which is being held a day
later in Rhode Island!

There is a sheet metal fixutre that you slide onto the fender and then attach
to the brake bridge. I think it would be very wobbly without it.
With a little care the zip tie job need not be a monster.

Whenever possible, the front fender tab should go behind the fork.

What's the reason for this?

That's the way the fenders are designed. If you mount them in front,
they don't go down far enough behind the front tire to give good
protection...even so, most front fenders greatly benefit from the
addition of a mudflap to protect your feet and your drivetrain.
If you look at the mounting tab of most better quality front fenders,
you'll see that it is curved concave forward to fit neatly against the
back of a typical fork crown.

I always thought that a mudflap was a necessity no matter what....

Ok, thanks. The first fenders I mounted were on a bike with a recessed
allen bolt on the front brake so I didn't see much choice except the
front (is there an alternative?), and I have just continued doing this
without much thought. A six inch piece of neoprene as a mudflap gives
me coverage for feet and the bottom bracket, so I guess I haven't
missed th extra 5 degrees or whatever of coverage by going to the back
rather than the front. But now that you mention it, that concave bend
to the ESGE/SKS bracket has given me pause to wonder once or twice :)

Thanks Sheldon!
I'll stop by in the fall to purchase said fenders.

Check this page out:

The upper photo shows the piece they use to mount fender to fork crown/bottom
of steerer tube from underneath.
The mount is held in by the brake caliper bolt with sidepulls and centerpull
brakes.
A seperate bolt is used for canti's.
Don't know if Jitensha sells it seperately.
I made my own out of a piece of stainless.
Requires three holes and two bends, dimensions become pretty obvious when you
look at bottom of steerer tube.
