When you're riding on the tops of your bars, but still want access to your brakes, Tektro has the solution- inline brake levers that work in conjunction with your road levers! 31.8 mm clamp diameter allows you to mount them on nearly any modern drop bar.
With a variety of form factors to provide you with exactly the ergonomics you want, our Thumb Tap shifters combine light shifting effort with a wide range of derailleur compatibilities.
The FR-4 is designed to fit the 20-spline tool fittings found on older SunTour® freewheels. Constructed from heat treated alloy tool steel, the FR-4 features a 1" tool fitting for use with an adjustable wrench, socket, or bench vise.
