The other answers answer your specific question of buying interruptor brakes. Interruptors are fine, but they only work when you're riding the bars and you can't shift on the bars. You should really fix the main problem which is comfort and reach when riding the hoods, which is where most people like to have their hands when road biking. It's both a safety ...

It is true that the old style brake levers were not as powerful from the hoods as modern ones. The reason is geometry. The picture below shows how old and new levers move when pulled. With old levers, braking from the hoods requires one to pull back and push down at the same time. As said in comments to other answers, this is doable but not very effective ...

I am a maker of custom bikes for kids and small adults. I am a heavy user of the interrupter-style levers, even for main brake levers. The main reason that I use them is that they are easy to adapt to a custom bracket which fits smaller-diameter handlebars and smaller hands. Another great benefit, they are some of the lightest levers available, period, at as ...

Those brakes are designed for cyclocross which means using STI "brifters" as you no doubt have on your bike. Interrupter levers are also designed for use with STI levers. The trio should be perfectly compatible. One exception to the above would be if you had "mountain" brakes designed for MTB levers. But that's not the case here.

Regular brake levers, without hoods or any additional levers or extensions, are intended to be used from the drops (i.e. riding with your hands down in the lower handlebar position). So, if your riding environment dictates that you might need very quick braking reaction, you would need to ride with your hands down in the drops. Most people - on many typical ...

What you are talking about are extension or suicide levers, which were common in the 70s. These were poorly designed -- they basically keep the cable tension for the brakes partially on, so you don't get the full ability to actuate the brakes. Modern bicycles have interrupter levers, which push the housing rather than pull on the cable to activate the ...

As long as you have brake cables that route under your bar tape (at least one black tube that pops out of the bar tape) you should be able to install interrupt brakes/ cross levers. I'm not sure if it would help, but you should also be able to shorten the reach to the lever on your existing Sora shift/brake levers and that may put the levers in a more ...

I've got Tiagra triple shifters and interruptor brakes; I don't see why Sora would be significantly different. While they are more common on CX bikes, there's nothing fundamentally different about road bike handlebars that would make fitting them any different.

I can only speak to #1 "Can it decrease the braking efficiency of the main levers?" Yes, it might, but not a certainty though. The amount of impact depends on the quality of your installation. Any join in the outer cable could allow compression, and cumulatively add toward sponginess in your brake lever. Also if the interrupter lever has a firm ...

Back in that era cables came out the top and partially blocked access the brakes. Once the cable was rerouted you have access to the brake from above so the need for extensions went way down. Common position is on the hoods and brake with 2 fingers. is-having-your-hands-on-the-hoods-of-drop-handlebars-safe-for-braking

A simpler alternative would be to use inline barrel adjusters to join the two sections of outer. That would avoid having to re-wrap the bars and means you could put the levers back in if you wanted to. Just release the inner wire from the brake, pull it out as far as the interrupter lever, remove the lever, inster the barrel adjuster and re-thread. Then wind ...

When I wrenched for a cross team we just taped over the housing. We also would position the levers further out (unless you're running narrow bars.) Keep in mind there's no need to pull the tape so tight that it would bend the cable housing. You want to pull the tape just snug enough so it doesn't slip. If you get to the end of the bar and let go of the tape ...
