About :

105 Di2, Ultegra Di2 and Dura-Ace Di2 are the three electronic road groupsets from Shimano that you're probably already familiar with. They all share a very similar design, performance and aesthetics, have a 12-speed cassette, wireless shifters and are 100% compatible with each other. But... what's the difference? Exactly how much does each groupset weigh in total? And each component individually? Is the more expensive Dura-Ace also far superior in performance? And does the more modest 105 really measure up? In this video we have the answers to these and many other questions. All the components of the three groupsets, including their options, have been weighed separately on the same scale. We have also disassembled and examined them as best we can - each new generation makes it more difficult for us to verify the real differences between each groupset. We haven’t provided official prices due to the variations they often suffer, but we have provided the percentage difference between them: -The price of a complete Ultegra groupset is 44% higher than the 105 -Dura-Ace is 129% higher than the 105 -Dura-Ace is 58% higher than the Ultegra bike.shimano.com Chapters: 00:00 Introduction 00:43 Levers 02:22 Rear derailleur 03:36 Front derailleur 04:23 Calipers and pads 05:16 Rotors 06:49 Cranks 08:16 Cups 09:06 Cassette 10:33 Chain 11:20 Pedals 12:38 Common components 13:17 Total weights 13:52 Which one to choose? 14:52 Conclusion ------------------------------------- FOLLOW US ON THE INTERNET AND SOCIAL NETWORKS: WEBSITE: https://www.ciclismoafondo.es/ Facebook: / ciclismoafondo.es Twitter: / ciclismoafondo_ Instagram: / ciclismoafondo_oficial Other Sport Life Ibérica magazines: https://www.sportlifeiberica.es
