[Closed] Is 11spd Shimano Road and MTB kit compatible?

Di2 ones are, no idea about mechanical, I'd go with no if I was a betting man.

Looking for a cassette bigger than 32t? The 105 11-speed stuff has a rear mech and cassette thats goes up to that without mixing and matching.

i have a feeling the 10 speed DYna sys (shadow plus) mtb mechs have identical cable pull to the 11 speed stuff.
WIll be trying my spare xt clutch mech with my 105 11 speed STis later today.

Daver27 - can you post up your findings.

Got 1x10 11-36 with a 38t chainring on the cross bike, a 11spd 11-36t would have a bit better spacing between the gears smaller jumps

Will the new M9000 XTR derailleurs work with 11-speed Dura-Ace, Ultegra or the new Shimano 105 STI shifters?

In typical new component group fashion, no. The cable pull is different. No clutch option for road Shimano road shifters yet.

Not quite sure why you'd have that feeling, FWIW [url= http://www.cxmagazine.com/shimano-xtr-m9000-11-speed-road-compatible-questions ]this[/url] disagrees, no compatibility between 11 speed road and 10 or 11 speed MTB. But that is the party line, so could be a slightly biased view. That said, not sure what Shimano would stand to lose by saying that aren't cross compatible.

Edit: actually you may be onto something, from [url= http://velonews.competitor.com/2014/07/bikes-and-tech/technical-faq/technical-faq-1011-speed-compatibility_337803 ]here[/url]:

Shimano’s mechanical road 11-speed cable stroke is a road version of 10-speed Dynasys for mountain bikes (which has a longer cable pull per millimeter of derailleur movement than 9-speed MTB shifters).

I'm certainly interested!

Presumably shimano mtb 11 spd doesn't need the wider cassette body like the road stuff due to the overhang of the larger sprockets missing the spokes due to the wheel dishing.

But is a 11 spd mtb cassette the same actual total width (i.e not cassette body width ) not as a 11spd road cassette? How thick are the sprocket spacers?

Exactly.

They'll be close enough - the 10 speed MTB/road ones are actually 1mm different over all and they work interchangeably (although Shimano say they don't). The issue is cable pull on the mechs.

and me!

Does that mean i can use my xt 10 speed clutch mech with my 11 speed shifter?

If that statement I quoted is true, then yes.

I'll be trying it as soon as my 11sp 'cross bike arrives any time in the next two weeks...

I'll be trying it this week. Just need to get an 11 speed power link

Er.. anyone know where i can get an 11 speed powerlink? Seems the one's i've found are non reusable or you need a special tool.

i've always ran sram powerlinks on all my bikes

Tricky - try a KMC 11 speed chain link - should fit.

Sram's are power locks in 10 & 11speed, they can be removed (unofficially) but you'll need the plier type tool to do it unless you've got fingers of steel.
Try KMC or Wippermann

That's exactly what I read njee. I'll be giving it a go tomorrow so will let you all know!

Righto, just gave it a go. It's a resounding NO! I get 9 gears working flawlessly and there are 2 points it needs a double up/down shift to make it change on sprocket and I can't get the last 2 sprockets. Oh well

Worth 10 mins to try it tho.

Booo 🙁

Why the hell can't shimano make a clutched rear mech for cross is beyond me! Were they the first to come up with it?

Sram have got ahead of them on that front with the cx1 groupset

Just a shame it's tied to their chappy brakes.

Double post

If it's that close can you not change the pull ratio slightly with washers/spacers? like you can with the 9/10 speed sram/shimano mixing?

Going on from the 11 speed powerlock/link post. I decided to try a 10 speed link and it worked fine.

Raced cyclocross today runnung 1x11 with a narrow wide chain - no clutch and no chain guide. Worked perfect in very sloppy mud

Also.. the rs685 brakes are amazing!
