Yes exactly, no need to take fingers off the brake when using them. They are for use on the climb.Are you talking about the hook like things that go on the ends of the handlebars? If so, no. I don't know if there was a section long enough that I would want to take a finger off the brakes.
An older friend who has been riding for 20 plus years suggested I try a set. Not sure about your area but places around her they are a must have .
