Replacing bicycle cranks on your road bike. Cranks Ultegra and Tiagra

Hello to all bike mechanics! This 13 year old road bike was fitted with Shimano Ultegra 10 speed cranksets. After so many years, the bicycle connecting rods have worn out. It is no longer possible to find parts for Shimano Ultegra cranks at 10 speeds. We were forced to replace the bicycle connecting rods with more modern ones, but of a lower level. This is a Shimano Tiagra level bicycle crankset. 00:00 Shimano Ultegra cranks. 00:05 Road bike cranks are worn out. 00:15 Unboxing shimano Tiagra fc-4700. 00:58 How to remove crank on a bike. 01:37 How to remove bike pedals. 01:53 How to remove bicycle crank Hollowtech ii. 02:28 How to remove bicycle Hollowtech bottom brackets. 02:49 How to lubricate bicycle Hollowtech bottom brackets. 03:05 How to installation bike Hollowtech bottom brackets. 03:28 Compare cranks Shimano Tiagra and Shimano Tiagra. 03:50 How to installation cranks on a bike. 05:56 How to clean and lubricate the threads of bicycle pedals. 06:59 How to installation move bike pedals. 🆗🎥🚲 Write in the comments, what you would like me to do in the new video. ⚠ ❓ ⚠ Ask your questions in the comments 👇👇👇
