Imagine, you’re trudging along some long flat gravel road. You’re nearly falling asleep when ALAS a slight upward gradient! Now, most would simply tap the back of their brake lever sideways and off they go, spinning up the hill, but not you. You elegantly reach your hand down and ever so slightly pull your Silver Bar End Shifter upwards dropping a gear or two while simultaneously activating a tailwind that is not only refreshing, but pushes you up the hill without you having to spin at all. What bliss!
Sold as a set.
These bar end shifters have a similar power ratchet system to the revered Suntour Power Shifters and Barcons.
