[Closed] Twin Blade Brake Lever for Disabled Rider?

Hi

I've fitted a few twin pull levers for people over the years that would pull both brake cables with one lever so they can operate both brakes with one hand. Not an ideal solution but at least you can set the cable so the rear comes on a bit less than the front.

I've got a friend with no fingers on his left hand who wants to ride offroad a bit and obviously can't use a rear brake on its own.

When looking into twin-pull levers I did see some twin-bladed levers that had two levers mounted together so you could pull either one individually or both together with one hand. I can't find them now despite having a good Google and searching old threads on here too.

Anyone?
