Using this Shimano Dura - Ace shift and brake lever is easy. First, install the lever on your handlebar using the band clamp that fits 23.8 - 24.2mm handlebars. Connect the 1800mm inner shift lever cable properly. When shifting gears, a short push on the lever will smoothly change the gears thanks to the shorter lever stroke. For braking, just squeeze the lever, and the hydraulic system will provide consistent stopping power in all weather. To adjust the lever to your liking, use the reach adjustment feature to set the lever blade position. As for maintenance, regularly check the hydraulic fluid level and top it up with mineral oil if needed. Keep the lever clean by wiping it with a soft cloth after rides. Avoid using harsh chemicals that could damage the components. If you notice any issues with shifting or braking performance, it's a good idea to take it to a professional bike mechanic for a check - up.
