Cable Liner or Donuts(5 posts)

Most bicycles nowadays have the exposed rear brake cable running along the bottom side of the top tube. Mine happen to have three rubber donuts keeping the cable from contacting the TT. Is there an advantage with the donuts over using the teflon inner liner of the brake housing?

I was thinking of replacing the cable and thought of using the liner instead. Also, I periodically snag the cable when pulling or replacing my bottle in the cages. I ride a size small Giant TCR so the space between the TT and ST is pretty tight. My thinking is that the liner would offer a little more protection than the donuts, particularly if I snag the cable.

Use the liner if you don't want scratches...russw19

The donuts sort of work, but the little teflon liners are better. The weight is absolutely insignificant and one nice thing about the liner is if you cut along it's length, you can put it over the cable and it will tend to wrap itself around the cable still. That way you don't have to take off the cable to install it.

Good idea. You learn something new every day! (nm)innergel

Cable liners tend to fill up with water if you ride in the wet and/or wash your bike a lot. This is not a significant issue if you use stainless cables, but if you use teflon coated cables, they will rust since most coated of cables use a carbon steel wire. Cable liners also make taking the brake cable out of the split cable stops more difficult/impossible if you're prone to doing that.

Take it for what it's worth, but I vote donuts.
