Bicycle Mechanics - Inline Brake levers for 25.4 mm mountain bars
Bikeforums.net is a forum about nothing but bikes.

I have a set of Scott AT-3 bars. They are mountain bars with built in barends that curve forward 180 degrees giving a hand position ahead of and parallel to the standard straight bar position (Like a big paper clip). I would like to find an inline brake lever to put on the forward end, so I have two front brake levers, but all I can find are levers for road bars. (I searched and searched and searched this forum and the net) :( The bike is a hybrid with V Brakes.
So if these levers dont exist, can I use a 26mm lever with some sort of shim or collar?
And if I can, I would put it on myself, but I have never done this or anything with brakes. I can figure it out I am sure, but since it is the brake line, is there anything special I should know BEFORE rather than AFTER I hit something? :eek:

inline lever will have a different pull lenght than your standard V levers. You could get a cable multiplier to make the inlines work, but then your standard levers wouldn no longer be functional.

The cable pull thing is no big deal, but I can't see the setup you're considering. If you want a lever at the end of the bar and another one by the stem, you're better off putting the regular lever at the end and the inline one at the stem.
Of course you can use a 26.0 lever with electrical tape, a strip of rubber, paper or whatever as a shim. No problem at all. I'd recommend Tektro rx2.0 or whatever it is called.
You just cut the housing at the appropriate spot, file it smooth, put end caps on, install the lever, thread the cable through. Brake and lever setup, etc. is covered in detail on sheldonbrown.com.
Oh, back to cable pull: inline levers are designed for cantis, which I feel need a similar amount of pull as V's; more than road calipers. You should be golden.

man, where did you dig those bars up from? Gosh I have set that goes further and comes together again in front to form an areo bar :)
inline levers are to be placed between the main levers and the breaks. you gotta ask if having them in the further forward location will effect a climbersome cable routing

I have a set of the AT-4 bars on my SM400. The front "aero" piece is great for getting down low and flat for short paved sections between trailheads and also makes a handy brush guard for your hands when you are back on the top section.

Cantis use the same cable pull as road calipers. V-brakes are different, and need more cable pull. So if you've got v-brakes, inline-levers designed for road calipers or cantis won't work well.

Scored them off fleabay. They are great. Mine are like yours but you sound like the AT-4 which has the aero thing. These are WAY better than my old bars.
Thanks anyway everyone, Just taped up the bars and seem to be okay with out the extra lever. Until tattoo something with my face ;)

Performance Forte levers have a cable end position for either cantis "C" or Vee "V" and work well with road cantilevers Set up my road bike with them and have had no problems stoping even on steep mountain road.
As for the intermediate lever there is a setup I have seen on roadbikes that uses the cable housing as a stop and when you squeeze the lever it lengthens the effective cable housing relative to the cable. I think that this is a setup that would work for you. This is a relatively common setup.

Cantis use the same cable pull as road calipers.
I'm pretty sure that's not true. It doesn't matter for the OP now, but I'm curious: where does that info come from? My tektro inline levers pull 2x as much cable as my time trial (road) levers.
