Using your Cube Attain GTC SL road race bike is a breeze. Just hop on, adjust the seat and handlebars to your comfort, and start pedaling. When riding, use the Shimano Ultegra 2x11 transmission to shift gears according to the terrain - lower gears for uphill and higher for downhill. The all - weather Shimano Ultegra hydraulic disc brakes are very reliable, but make sure to give them a gentle squeeze first to test their responsiveness before you start a fast ride. Regarding maintenance, keep the bike clean by washing it regularly with mild soap and water. Avoid using high - pressure water on the internally routed cables. Check the tire pressure frequently, as the lightweight Fulcrum Racing wheelset performs best with the right pressure. If you notice any unusual noises or changes in performance, it's a good idea to take it to a professional bike mechanic for a check - up. Also, since it has mudguard compatibility, you can easily attach mudguards in wet conditions to protect yourself and the bike.
