Details
Also known as a cable doubler
The Double Control model L (long pull) is a cable splitting device with 2 applications:
1) It allows you to combine two shifting levers for control of shifting your bike. People with clip-ons can now shift while riding in their aerobars just like the people with dedicated time trial bikes, plus they can also still use their drop bar shifter too!
2) It allows the addition of an extra brake lever when using V brakes or mechanical disc brakes. It IS NOT to be used with short travel (road) brake levers.
This was designed primarily for gears and if used for brakes it's ONLY for a V brake (long travel cable) there is less compressional force on the cable which is ONE of the reasons V brakes are more effective. Further the PRIMARY road brake lever should use the straight run of cable, the AUXILIARY lever should operate the doubler.
- Super lightweight, only 16 grams.
- Maximum cable travel 27mm
- Best of both worlds: shifting in aero position or using dropped bar shifters.
- Clean and small design.
- Works with both front and rear shifters.

Hi
Double control USA was manufactured in the US, this one '19040' is manufactured in Asia. There is no other difference apart from colour.
Thanks

Do you have these? There doesn't seem to be any way of contacting them through their website. I'd like to ask them if they could do a special for me.

Can I use this in Reverse?
By Tim Danaher
11 Aug 2019
Basically, I need to control two brakes using one lever (lost right arm in accident). Could this be used in reverse to allow that? Also, can you confirm that one of the cables is continuous (runs uninterrupted from lever to brake)? I'm using a Primo Pervert ATM, which is a discontinuous-cable solution, so not ideal.
Cheers,
Tim

SJS Customer Service:
No, can't be used in reverse. You need either Problem Solvers Cable Doubler 1.2 (SJS Cycles part number : 18243) or SJSC Twin Cable Pull Brake Lever for Straight Bars - Right (SJS Cycles part number : so104897)
Is this one or a pair?

Double Control Model L Compatibility With Short Pull Brakes
By Tyler
30 May 2017
Hello! Does the Double Control model L work essentially the same as the Double Control model S, the only difference being the model L facilitates an overall longer cable pull? I'd like to purchase the Double Control for my cantilever brakes and was considering buying the L version for the sake of future proofing my setup, should I switch to long pull brakes later. More simply put, does the Double Control L work for short pull brakes as well?
SJS Customer Service:
No, the long travel version is for gears and if used for brakes it's ONLY for a V brake (long travel cable) there is less compressional force on the cable which is ONE of the reasons V brakes are more effective. Further the PRIMARY brake lever should use the straight run of cable, the AUXILIARY lever should operate the doubler.

Doublecontrol L For Breaks? Difference To Cabledouble 2.1?
By Pär Lindfors
19 Jun 2016
Can I use this (jtek double control L) instead of a Problem Solvers Cable Doubler 2.1? Can you explain the main difference between those two products?
My project is to be able to control a single break from two different levers.
The double control is half the price, and by looking at the pictures, assuming I understand them correctly, the double control seem to be a much simple and more durable mechanincal construction. However, according to your product description, the "double control S" is for breaks, but the "double control L" are for shifters. That does not really make sense to me.

Hi,
This Jtek double control L is designed for use with gear shifters rather than brakes like the Problem Solvers cable doubler 2.1. The double control S would be the correct one for use with brakes. The Double control relies on the spring tension in the brakes where as the cable doubler has its own sprung system.
Thanks.
