Cantilever Brake Hangers

For a Surly Cross Check. I need a front cable hanger for the cantilever brakes. I'm considering these two.

What are the pros and cons of each style?

Get the first one. Read up on brake shudder if you want to know why you should buy that one. Sorry to not play along with your pros and cons assignment, but Simon didn't say.

The only reason you would buy the second one is because you either don't have a hole to mount the first one in your carbon (you can drill a mount hole in steel) fork or are just too lazy to untape your bars and put in a longer piece of housing on an existing setup where you want to flip/slam your stem.

Get the first one.

Assuming you have the standard Surly fork either will do. The "brake shudder" Dan refers to is a problem mostly with carbon steerers and their flexibility. The Surly has a 1-1/8" steel steerer which is far more rigid so the second hanger will work ok.

The first hanger will fit the Surly fork as there is a hole in the fork crown that will accept it.

Your choice.

I like this type myself: http://www.specialized.com/us/en/bc/...jsp?spid=47409 It is slotted to allow removing the cable without unthreading it. Brake shudder may still occur even with a steel steerer if a stem mounted hanger is used.

Shudder isn't just a carbon steerer thing, it's a hit the brakes, the fork bends back, which tightens the cable, which locks up the wheel which springs forward which then bites again and the whole process repeats at about 75 hz.

I have a 1 1/8" motobecane that does it, I have a friend with a LHT with the surly canti fork that does it. It's just what happens when forks are designed to flex to smooth out the ride and cables are hung from a place that isn't flexing with the fork.
