which of the brake arms, is the cable  anchored to?
does it slide straight thru both brake arms and back into the headtube
with out it being anchored to either brake arm?
Title: Re: dual front how too:
Post by: blind on March 28, 2010, 01:33:46 AM
yeah its anchored at the lever not the brake arm
Title: Re: dual front how too:
Post by: Havokflat on March 28, 2010, 05:50:46 PM
yeah its anchored at the lever not the brake arm
you mean the ONLY anchored point is the lever?
the cable slides thru both arms freely?
how does it pull the brake then?

no one?

the tension pulls the only moving part (arms) together

  Everone seems to use a knarp.  Anyone use the luck bolt?  I think it will look streamline if you can cut the hexagon off and it should fit flush into the brake lever.

it doesn't stick out far.

it works, btw, thanks guys ;D

you dont need to cut the hexagon off it still works nicely

i do have a small issue.
one of my levers require me to pull it farther than the other.
is there any adjustment at all?
i've tried fixing it at the barrel adjuster, but it doesn't seem to make much difference.

the other lever works perfectly.

i think its cause this a little more or a less commonly used thing. and hey btw why dont you cut those cables a little shorter so you have more room? they seem to be sticking out a little more than necessary

the lever feels spongey, and i can't seem to adjust it out. :angry:

I had a similar set up a while back, but didn't use a knarp, just used two equal length outer and inner cables, and joined the two inners up between the brake arms using a regular cable clamp that I drilled out a little so they'd fit through... same theory as the knarp technique only you clamp the cable between the arms and not at the brake lever.

my problem was a frayed cable.
the fray was close to that lever, so the other lever worked perfect.

a new cable fixed me right up. ;D

I've done the same thing that Blind showed you how to do but instead of using the knarp that way you can take a drill and drill a hole in the side of your lever, so the cable goes threw the lever,threw the knarp,and out the hole,then you can pull on the cable nice and snug then tighten down the knarp,cut off remaining cable and it works like the bomb,another tip you can do is,you can illiminate the adjusting barrels and run your cable straight to the brake arm itself,and just use your adjustment from the levers,start by adjusting your barrels out almost all the way,pull your cable tight,tighten knarp,at this point you won't be able to pull levers at all,then adjust your barrels down towards lever equally and you should be happening.when drilling your hole just use a bit a hair bigger than the inner cable itself.   Armstrong

that's a handy tip.
 it always takes me twice, trying to get the cable the perfect length,
because it hits the lever.

Thanks for that tip, it's genius (-:
