Yes common failure that almost broke the cycling interweb a while back. Here's the AI summary:How did that happen? Was that a "common" failure? Do you have any proof or documents about it? If that was a common failure of that groupset, I am very sure there is plenty of documents, threads or info about it out there.
Or was that some african lorry that blew over some random biker in Spain or a sledgehammer that demolished the bike and a pic was taken to make some weird story about alleged failing 6800 Ultegra cranks?
I absolutely agree, it is the groupset that I am chosing for all my roadbike projects. It is much better designed than the modern Shimano stuff, it doesn't have the cranks breaking issues nor the later dura ace shifters cable eating issues. It is absolute reliable, lightweight and well engineered. In second Dura Ace 7700I'm gonna have to say Dura Ace 7800. Beautiful, light, stiff, no fuss, shifts like butter and could still win Grand Tours today.
2. SRAM Red 1st Gen - super.
3. Tiagra 4700 - excellent, shifts like top end groups.
4. 5800 shimano 105 - the best all rounder.
5. Ultegra 6500.
Campagnolo - not much experience from me.
That is why I always avoided the 11speeds Ultegra and Dura Ace seriesYes common failure that almost broke the cycling interweb a while back. Here's the AI summary:
