Bicycle Mechanics - Help needed fitting TT levers to bullhorns

Hi all,

I've recently chopped the bars on an old racing bike and flipped them to make bullhorns. In order to finish the job, I bought a pair of TT levers to use instead of the old brakes.

After fitting the levers and changing to MTB cables (the ends are round, not mushroom) I've got a major problem: The cable housing is pulled through the bottom of the levers, making the brakes useless!

Here's a pic of what happens when I apply the brake:

and of the resulting effect on the housing:

It's almost like the cables are too narrow for the brakes, abut they're just standard brake cable bought new from a reputable bike shop.

Any ideas????

Two things...

1. You should be using a ferrule on the end of your housing.

and, more importantly,

2. I believe those levers have a cable stop that is supposed to go into the hole that the cable passes through that you seem to be missing.

Here is a good source for info on cutting cable housings and finishing them. http://www.sheldonbrown.com/cables.html
You may also want to refer to Park Tool repair advice. http://www.parktool.com/repair/

there should be a cable stop there like a adjustment barrel so the housing doesn't do what it has done here.

Thanks for the quick responses- I've been through Sheldon's fantastic guides previously, thanks.

It was just the ferrules I was missing - found them in the bottom of the packing for the new cables and they've solved the issue.

Cheers guys
