    Single handed operation of both brakes Primo Pervert or replacement

    My son was born without a right hand – when he first started riding two-wheelers my research led me to using a Primo Pervert cable splitter to facilitate safe braking (both brakes operated by a single lever, set-up so that rear brake is applied just before the front brake).

    My son does not ride a lot, but this ‘Pervert’ mechanism has operated flawlessly. It has been transferred to successive bikes – most recently a Trek FX hybrid, where the Trek store did a tremendous job for a nominal cost (they also ‘mixed & matched’ to enable operation of both derailleurs - front using a trigger mechanism, & rear using a twist mechanism).

    Attached three photos show:
    ~ overall set-up , with the ‘Pervert’ shown in lower left corner;
    ~ close-up of other side of ‘Pervert’ when brakes (i) applied and (ii) not applied to try to illustrate how it operates.

    We are now wanting to set him up with a bike for university – the Trek is too nice, so will buy a cheap second-hand one. We therefore need another mechanism to operate both brakes from one lever. As far as we can see from the internet, Primo have discontinued making the Pervert cable splitter (perhaps they could have chosen a better name?).


    Does anyone know whether we can still buy a Primo Pervert cable splitter, or whether anyone can recommend a mechanism which will achieve the same end result (reliable safe braking).

    Late news: I have found a single lever which purports to operate two brakes at once – anyone have any experience with this product http://www.amazon.com/Pyramid-Alloy-Mountain-Cable-Brake/product-reviews/B000AO7H16/ref=dp_top_cm_cr_acr_txt?showViewpoints

    Get a Problem Solvers Cable Doubler 1:2. Any shop with a QBP account should be able to get one.

    Bezalel,

    Thanks for the recommendation - the Problem Solvers Cable Doubler 1:2 seems likely to achieve the objective

    I have one of those on my MTB - didn't know it was called a pervert!

    I have a newer one of a slightly different (and better) design on my latest bike which I bought from my local shop. I've seen the double lever, but only over in the States (I'm in the UK) because that will make a neater solution.

    However, I'm currently looking to sort a Y-splitter for a hydraulic line.
