i got the c50s. very good rims but a bit porky at 1780~1790. reviewed them on my blog.


Good review, thanks. Really just looking at the front for a goto TT wheel. Toss up between these and HED Jets at the moment.

This is THE post I have been looking for. If you could get out and put both combinations through some serious 'real world' tests it would be most appreciated.

There's been a great deal of speculation flying around about these combinations but no one has actually made a FULL report.

Did anyone try the Dura Ace 9000 bottom bracket with older Dura Ace cranksets, like 7900 or 7800?
I guess that they should fine, however it would be great if someone already has first hand experience with this setup.
Thanks in advance.

The new 9000 bottom bracket is intended to be used with the same 24mm BB spindle as the 7800 and 7900 cranksets have. It is only the bearings and, thus, the outer diameter of the cups that are smaller.

That's why there is an adaptor included by shimano to allow use of existing hollowtech II BB tools.

Thanks for the information.
What I was mostly worried about is the width and if eventual spacers might be needed, if the cups diameter are the only size change then this should fit well, and it will also be fairly light, 70 grams or so from what I have heard.

Has anyone had their hands on the 9070 DI2 shift levers yet? How is the hood shape compared to the 7970? It looks a little smaller in circumference. Is that actually the case, or is it an effect of the different coloring and texturing on the 9070 hoods?

So does that mean the press-fit 7900 BB is compatible with the 9000 crankset?

Not quite what you're asking, but for reference people may find it useful to know that using a 9000 bottom bracket with a 7800 crankset is an extremely tight fit - it works fine, but just getting the spindle through took a lot of force.

On the other hand, I found a 9000 crankset fitted easliy into a 2009 Hope bottom bracket and works fine.

That in fact is exactly what I wanted to hear.
Thanks a lot for the info! :thumbup:

The KMC webpage for the X11SL chain now has an explicit statement of Shimano compatibility again - interestingly, there is an implied compatibility of the MissingLink 11 with Shimano based on the chain's webpage, but the MissingLink 11's own webpage is notably devoid of any statement regarding fitting to Shimano chains or general Shimano compatibility.

Strange that the Shimano references disappeared and have now returned......

Interesting that a shop in Glasgow seems to be the first to have all the parts of Di2 9070 in stock...now they are selling it at full SRP so £2.8k for fr & rr mech, fr & rr brakes, internal battery & charger, cassette, chain, cables, crank, bb & sti's.

They seem to have 3 of everything you need though...now can I find any spare change down the back of the sofa....

I doubt you can checkout with the items and get a next day ship-out for them. :roll:

The bigger German websites do not have them but they usually will indicate that its a 20-day or more wait time if they do have them soon. I seriously doubt a less than "well-followed" website actually has them. Especially if you're outside Japan.
