Shimano Ultegra R6800 vs R8000
Anyone ride them, do you notice any differences between the two? Curious as I'm in the market for a new set to go with my R8000's

New set of what? There are a number of improvements to many of the components in the set, and I'd want a substantial discount to go with 6800 over R8000, or even over R7000. The exception would be the cassette and maybe the crank and chain.

I should have been more specific. The R6800 pedals vs R8000 pedals.

My 6800 pedals have about 18k miles on them without issues (and I am over 200 lbs). I doubt the 8000's are significantly better. I would get the 6800s if there is a significant price differential, and the 8000s if the prices are close

I know the topic was pedals. But I got a steal on a new-take-off R9100 crank, and the ramping and weight on that thing is stellar compared to my old 105 5800 crank I had. Like light years better. I went ahead and got R8000 FD, RD, and cassette also. I can feel some of the shift magic of R8000 that way, but miss out on the shifters. The most expensive and toughest parts to change over. But, still super satisfied.
I have the 105 or RS500 version of pedals from 3 or 4 years ago. They still feel fine. A few grams. I run speedplays on the TT bike for the aero and reduction in stack.

Um, once a bike has cables in it the hard part is done. Just run sleeve through it over the old cable before you remove it.

What difference could you hope to find between a perfectly good pedal (R6800) and the next model?

Had 6700 four 6 years??(about) thousands and thousands of miles. No problems
I had 8000 for a year and cracked the drive side crank arm. It was replaced under warranty. The 8000 was 172.5 vs the 6700 at 170. I’m not sure if that was a factor.
Also broke dura ace 9000 within a week of the 8000 on my only other bike and it was a week before vacation.

Yeah, not a fan of the bonded construction introduced on 9000...

Damn. How many watts you putting out. I broke an Ultegra 6800 a couple years ago and upgraded to the R8000 Crankset. So far so good. I'm a fan of Shimano despite that happened.

I was responding to the post about broken cranks.

My replacement 8000 and 9100(they couldn’t get a 9000) have held up about 6 months. Those both failed at around a year. The crack was identical on both. Maybe a coincidence
