Single vs. Dual Lines From a hydraulics point-of-view there’s no difference. However, the two-line configuration has a longer total hose length so you’d expect that you’ll have a little more volume expansion under pressure than with the one-into-two line configuration. More expansion of the hose will give a slight springy feel to the brake lever but won’t affect stopping power. The difference is so slight that the other factors mentioned should be considered instead. |
