Help me choose the right brakes for my Dawes Galaxy.

[sefton1275gt]

I have taken some Shimano m733 canitlevers off my tandem with the aim to fit them to my Dawes Galaxy.

However, I now suspect the bosses on the frame and fork are too narrow for these brakes to work optimally.

Below is 2 photos. One with the arm relaxed and one where I’m pushing it to the rim.

do I need the earlier shimano m732 (wider design)

Dumb question, because I’m not a canti expert, is that brake block up right way? It ‘looks’ upside down.

 

[sefton1275gt]

Yep it’s the correct way

Block looks the right way up to me.

I believe the cati levers should be close to vertical and parallel to work optinally so either your bosses are too narrow or your rim is too wide.

You will need wide profile cantilevers as opposed to the low profile fitted. @winjohn is correct.

M732 then. (Thought so)

I can use these m733 on a mtb build.

Are these pads touring pads?

If you're touring it's a touring pad

You can use a narrower pad like aztec control block
But leaving aside the boss width/ rim width issue,
- an additional problem is when the bike was built for 27/630 and now has 700/622.

In this case, about the only decent cantilever is the shimano "rabbit ears" like these br-m500s
Although the dearly beloved Brat-fifty (br-at50) can get pretty low.

But they do stick out a way.
Although this style has made a comeback, I think it was previously (almost) abandoned due to heel and pannier interference.

Brat50 are great. Was this a 27" wheel bike?

I would try thinner pads too...those seem very thick. Bbb make some nice triple compound.
