Do you ship to ???

yes, we ship worldwide, no problem.

Does the cost price of the Dualever include whatever set up i require i.e. if twin hydraulic, or cable & hydraulic, and  the different length & angle clutch & brake levers etc..
Yes, the Dualever will come set up to your needs. no extra cost.

I have a cable clutch and want to transfer it to the right-hand side along with the front brake – will the Dualever allow this?
Yes, the Dualever is able to offer both cable and Hydraulic operation on either the left or right h/side of the handlebars, whatever your setup requirement it is all included in the price.

How do I operate the levers independently?
The levers have a wide range of adjustment and can be offset from each other. Also, a longer lever (+30 mm) can be fitted to one module thus enabling two or three fingers to grab one lever and the other fingers can easily reach up for the shorter lever.

I have car callipers on the rear of my trike and a standard bike rear master cylinder does not have enough fluid displacement to work them – will the Dualever operate them?
The Dualever has a choice of bore sizes – either 14.0 mm or 17.5 mm we would recommend the 17.5 mm bore for your rear brake operation.

I have 1″ bars on my machine will the Dualever fit these?
Yes, the Dualever is supplied with an adapter that enables it to be installed on 1″ or 7/8″ bars.

If I buy a Dualever and subsequently sell the machine can I transfer it to a different machine?
Yes, even if the machine you are changing to has a different configuration, for example, hydraulic clutch instead of cable, providing you purchase an additional hydraulic module then the Dualever can be re-configured to so just purchase the parts you need not a complete new Dualever system
Can I purchase a matching clutch lever to operate a cable or hydraulic clutch?
Yes, a matching hydraulic or cable clutch lever that matches the Dualever system is available please inquire.

It’s unwise to pay too much, but it’s unwise to pay too little. When you pay too much you lose a little, that is all.
When you pay too little, you lose everything, because the thing you bought was incapable of doing the thing you bought it to do.
The common law of business balance prohibits paying a little and getting a lot, it can’t be done. If you deal with the lowest bidder, it’s well to add something for the risk you run.
And if you do that, you will have enough to pay for a Dualever  kit
