The Shimano Tiagra BL - 4700 brake lever set is a top - notch choice for flat bar road bikes. It's compatible with V - Brakes, New Super SLR calipers, and mechanical disc brakes. This comfortable, ergonomic lever has a reach adjust feature and pairs well with the SL - 4700 shifter. The Super SLR technology in this lever is a game - changer. SLR means Shimano Linear Response. Its design reduces friction in the caliper, lever, and cable, enhancing response and modulation. The ServoWave mechanism in the lever provides quick shoe - to - rim contact and a longer stroke from the start of braking for better control. It's also what makes the Shimano dual - pivot caliper more powerful than conventional side - pulls. The reach adjust mechanism is another great feature. You can adjust the distance from the handlebar grip to the lever to fit your hand size, riding style, and personal preferences.

Using your Shimano Tiagra BL - 4700 brake lever set is easy. First, make sure the reach adjust is set to your comfort. You can do this by adjusting the distance from the handlebar grip to the lever according to your hand size and riding style. When you're ready to brake, simply squeeze the lever. The Super SLR and ServoWave technologies will ensure a quick and effective braking response. Here are some things to keep in mind. Don't use the brakes too hard suddenly as it may cause the wheels to lock up. Also, make sure the brake cables are in good condition and properly adjusted. You can use the cable adjust feature if needed. For maintenance, regularly clean the levers and the braking components. Check the clamp band to ensure it's securely attached with a diameter of 22.2 mm. If you notice any unusual noise or reduced braking performance, it might be time to inspect the cables, pads, and other parts. Keep the internal bumper stop in good shape for smooth operation.
