Ok, for Shimano the new models numbers typically go to the next number in the series (+100). i.e. 6500 -> 6600 -> 6700 - > 6800

It was the same for Dura Ace until they hit 7900 and jump to 9000 but is now continuing again with 9100.

So, I'm wondering if they will really +100 to the latest model designation for Ultegra or not when 9100 trickles down. Considering the innuendo associated with the leading 2 numbers if they do so.

Should we start a pool on what they end up calling the next Ultegra model #?

Sitting here at work trying to get my mind off of a perfect **** storm of delays on a project I'm working on.

I won't bet on what they'll name it, but I think it'd be cool to revive the 600 name again. Then again, there's a lot of things I like about old-school bikes.

Why would it not be called 6900?

Dura-Ace skipped 8000 because 8000 belongs to MTB. There is no 6900, so I see no reason why they wouldn't call it that.

XTR - Dura-Ace's dirty cousin uses the 9000 series.

Shimano is in a common predicament (SRAM is there too) - completely future-proof naming systems are tough. Using numbers can be limiting. Look at BMW. Once it was 3, 5 and 7 and sometimes 8. Now, it's 1,2,3,4,5,6,7,8. They have no more room if (not sure how) they wanted to squeeze something in between the 2 and 3.

Contrast that with word-based system, e.g. Ford Mustang, or Scott Addict. There's no limit to where the brand can go - up or down market, renew every 2 years or 10 years. Companies can add more and more brands/names and nothing is "out of order".

Shimano's is sort of a hybrid - using both, e.g. Dura-Ace + 9000. They've used the "M" designation on the dirt for a while, e.g. M9000 (XTR).

They'll figure something out - could be D9100 and U7000... or some other system we'll mindlessly adapt to, learn and use like a second language

Yes, there is no "6900" officially at the moment...but with the ultra-over politically correct environment we seem to live in you wonder if they skip that number because of the number "69" itself and what it can also mean....or did you not get what I was implying in my original post?

Looks like the cassette spacing(edit width) is now that of the MTB line. I wonder what that will do with compatibility with 5800, 6800, and 9000 shifters and/or rear mechs.

Also, does that mean that if you have a 8,9,10 spaced hub that you could use it with the R8000 cassette?

Shouldn't affect compatibility with the current gen of 11 speed. The Shimano charts show that 9100 works with 9000/6800 shifters and such. Rear mechs obviously you'd need a long or medium cage (per Shimano) to run the 32+ cogs (I bet the 30t cog works just fine on a short cage). I wish they'd bring back a 12-28 for the Ultegra 11 speed though. Not willing to spend Dura Ace money for 1 cassette when I can buy 3 or 4 Ultegras.

I doubt you can fit a R8000 cassette on a 10 speed max hub....it would be the same as a 5800/6800/9000 cassette spacing so it would be a no beuno.

Looks like I didn't read it close enough its the 11-34T Cassette that is different.

"With the addition of the new 11-34T CS-HG800-11 cassette, ULTEGRA further expands gearing options for riders of any terrain. Designed to fit both MTB- and road-specific (with spacer) wheelsets, mixed terrain riders are provided with more wheelset options than ever before."
