You realise chucking a 9070 RD into a 6770 setup will only test one of the disputed points, that being if 10 & 11-sp F&RDs will actually talk to each other? 'Cos you're proposing to test it in a 10-sp. system, you're not adjusting the chainline as an 11-sp. will do, so it won't test the disputed trim difference.
What you need to do to test it all properly is chuck a 6770 FD into a 9070 system. I'm quite keen to test it out myself if I get a chance at work, I've got everything I need to try it.....

All I want to test if a 11 speed rear will work 100% in a 10 speed setup and make sure my sprint buttons keep working etc.
Then ill buy 2 rear mechs, 2 chains and 3 cassettes and ill be 11 speed on both my bikes..

how the hell are you going to test a 11 speed rear mech with a 10 speed cassette? are you that stupid that I have to spell it out point by point for you to understand? it seems everyone is on the same page but the pro bike mechanic just misses the plot all together..
FWIW I have already ordered 2 6870 rear mechs, 2 chains and 3 cassettes for my 2 bikes and 3 sets of wheels because I already know it works and works perfectly but I didn't take any photos to prove it to knobs like you.. If you had done your research on me you would already know that I have cracked the shimano DI2 protocol and am able to replicate it and don't even require shifters etc to make the system work properly so I dare say I have a little more knowledge on how the DI2 system works than you do..
lucky for me ive already converted 10 speed wheels to 11 speed with out changing free hubs. lucky shimano and zipp said it cant be done and you need to buy new hubs etc to do it.. no you don't, you just have to not be a bike mechanic to do it and actually have some brains in your head..
shimano 10 speed hub.. count how many cogs are on there..

If so it's nice to see someone circumvent to the planned obsolesence built in by shimano

Well do spill the beans Pics and a step by step guide would be nicedale79 wrote:yes you have to machine both the free hub and the cassette, but you have to do it in such a way that the cassette is not wreaked and cant be used on another wheel.. so its not just a matter of machining the back of the cassette..

Out of interest are any of the parts that make up the 6800 cassette carbon?
Cheers

Having now noted that 6870 is only a few months away I'm probably just going to wait until then anyway so it's a bit of a moot point for me now as I don't already own 6770.
