Cascade Components "Brake Feel" Dial 6

This one is pretty funky! It's basically an external brake lever add-on that allows you to move oil in and out of the lever reservoir. The effect is affectively adjusting how "full" the brake feels - like how if you overfill a brake when you bleed it, you get a really short lever throw. They're currently planning to make them for quite a few brakes where the reservoir cover is suitably shaped, stay tuned to this space!
