Details

Also known as a cable doubler

This is a double input, single output, DoubleControl cable splitter. It weighs just 12 grams and is super small and compact. It's versatile in that it can be mounted in a variety of locations including: inline, on top of the brake calliper, or at cable stop locations. It requires no internal springs and allows both brake levers to operate totally independent of each other while maintaining the same feel and function of a single brake lever system.

Please note that this model is designed to only be installed with road style caliper, cantilever or disc brakes which use shorter cable pull operation and is NOT designed for mountain bike style V or disc brakes, which will require our longer version (item # 19040).

- Maximum cable travel 12mm
- Offers clean cable routing.
- Great for team time trials and holding tight drafting situations.
- Ideal for triathlons where position controls is critical to avoid drafting situations.
- Huge benefits for racing technical courses and more efficient corner braking.

ConsExpensive.

ProsWorks well, small, tidy.

I use this to control a front caliper brake from both left and right drop bar levers on a fixed gear bicycle. Build quality and finish seems excellent and installation was straightforward with clear included instructions.

Mounting position on bike?

By Richard

21 May 2022

I will be actuating Paul Klamper disc brake callipers with SRAM Force levers on a WIDE gravel bar setup and want to employ the use of TT bars as an alternative position when riding long distances. Ideally these TT bars will have bar end levers so I can brake from both positions on the bike. This cable junction looks like a great solution to this but as I want to keep the cable-run along the frame to a minimum (I’ll be running a dropper post too), I’d like these junctions to perform their job at around the stem position. Is this possible?

Many thanks

How is the feel of the brakes after installation? Don't they become a bit too spongy?

By Krzysztof Sokol

27 Aug 2018

I am planning to completely revamp my current cockpit on my tourer/commuter. I want to go with Velo Orange Crazy Bar, so I would like to have secondary brake levers installed on the bullhorn part of the handlebars to have the ability to brake in more aero position. I am however worried that the adaptors would compromise the breaking power. Could your ensure me that it would not be the case and from both secondary and primary brake levers I would have similar ability to stop my bicycle, please?

SJS Customer Service:

Hi, the brakes will not feel any different to a single lever setup with this device. Thanks

Do This One And #19040 Come With A Spacer For Mounting Directly On Caliper Brake?

By Tom

19 Jan 2017

SJS Customer Service:

Hi,

This product (19041) comes with a spacer to allow for fitting directly onto a caliper brake. Please note the longer version (SJSC part 19040) is not compatible with caliper brakes.

Thanks.

Will This Work For Cable Disc Brakes

By Anonymous

12 Aug 2015

I am currently running Shimano Ultegra 6870 STI levers with TRP Spyre mechanical disc brakes.
Would I use this, S, or the L model.

SJS Customer Service:

Hi, the S model provides 12mm of pull whilst the L model has 26mm of pull available. We don't stock the TRP Spyre disc brakes so you will need to check how much pull is required to engage the caliper & then select the most appropriate model. Regards

Will This Work With V Brake?

Or is there another product that will do the same job? Note the comment about road caliper style brakes. Thanks

SJS Customer Service:

Hi,

No but you can use the Jtek DoubleControl L (long) for brakes that require a longer cable pull. Our part number 19040.

Thanks.
