Cantilever brakes to fit a '80s Shogun 2000

So I have this old Shogun touring frame sitting in my basement. I tried out a few different crane creek levers on the thing last year but just ended up $60 poorer.

Anyways, I finally found a pictures of the exact frame with the original brakes installed!

Does anybody know where I could find new canti brakes this size? I don't have specific measurements for the brakes, but will investigate before throwing money out again





And here are pictures of the frame at home with one set of poorly fitting cantis:

Try checking out biketoolsetc.com or thethirdhand.com or ebay or your LBS ( they might have something you could use ),they might have what you are looking for. What you have is a older bike with the braze-on set to high (common back then ) . You could take the bike to framebuilder and have them move the braze-on to lower place to work with the brakes you have.

Those are a really old style of shimano cantilever brakes about 1988 vintage. I found out from personal experience that they don't work well with panniers on touring bikes. The ends stick out so far that when I put panniers on my Stumpjumper that the panniers were resting against the ends of the brakes and pushed the brakes onto the rims. so I was riding with the brakes on when I tried to tour with that setup.

These that I found on amazon.com look like they would work, but maybe not, that rim is so close to pivot point.

BTW what size wheels do you have on the bike?

and what year is the bike?

The reason why I ask is maybe you have a 700c wheel in a frame that takes a 27" wheel.

I'm pretty sure I have a used set lying around here in a parts bin.

3rd and 4th picture.. Looks like you have a 27" wheel frame
with a 700c wheel in it.

Low profile cantilevers + aero levers require a very slight rim clearance .

OTOH High profile will not. it's all about cable pull .. leverages

I run Low profile Calipers and Non aero Brake levers on My Touring bike ,
the previous type lever pulls more cable

Levers with aero style pull less, , If a high leverage caliper is used
It Needs more cable pull than the lever offers.

Hence the 2mm pad to rim clearance..

I believe the wheel in the picture is a 27 inch rim. I hadn't even considered it, but I'm pretty sure this bike was designed for 27" ... something else to think about when putting this back together.

I don't plan on using this for touring, so the pannier thing isn't an issue. I'm also noticing that the front fork is drilled for a caliper brake as well... I might mix it up and only have the cantilever in the back

Capecodder - if you're looking to sell similar sized cantis I'd be more than glad you paypal you and see if they fit!

cyclist2000 - I have a very similar set of brakes to those you linked to. I have them set up with kool stop thin lines (?) to get them even lower... still slightly too far from the rim. At one point I had the brakes hitting the rim at an angle that would stop the bike, but wouldn't feel safe riding something like that in city traffic

If the for has canti posts and is drilled then the hole is for a fender. A caliper brake may fit but it will need to be a long reach.

This is why I think that you may have 700c rims on a frame made for 27" wheels, the rims are so close to the posts.

This is a photo of mine on my Stumpjumper it looks like I have about 1-1/2 inches from center of the post to the top of the rim.

Pretty sure I've seen modern high profile cantis. They might fit, if the old one did. I think they're mostly marketed towards Cyclocross, these days. I've actually got an older BMX bike, with the same problem. (compounded with the brake mounts being too far apart) I wound up getting a set of Paul's MotoBMX brakes, to get the range of adjustment, I need. The MotoLites would work just the same. I just bought the one, that the store I use had. They can be adjusted down to roughly 20mm between the center lines for the brake posts and the brake shoes, maybe a little under.

I found them.... They are not similar, they are exact and they have the straddle cables and hangers, but they need a good cleaning, and the bolts should be hit with some WD and steel wool. They are yours if you want them PM your address. I can toss the bolts in a OA bath for a couple days if you want.

The brakes you're looking for are Shimano AT50 cantilevers. They are very similar the early Deer Head XT versions. The ones pictured above are the Shimano BR MT60 version that came later.

You can usually find them on ebay for approx $25. Good luck.

That is incorrect.... The ones I have pictured above are BR-AT50

Update for posterity's sake:

I found a nice set of 27" wheels and in combination with Tektro's generic cantilevers, the brakes can be set up with a proper amount of rim contact!

Thanks all for your help. If you have this bike don't even attempt to put 700c wheels on it.

Also, I think the Tektro CR720 might be an even better bet for these wheels, but I can't comment since the generic ones are working fine.
