Moooving Posted October 26, 2018 Share Howzit guys Seeking some advice please. I am looking to buy myself a new crank - Shimano 105 7000 53-39T 11 speed. I currently have a 10 speed drivetrain with the following components :Shimano Ultegra 6700 10spd cassette 11-28TShimano Ultegra 6701 10spd chain The big question is will I be able to run an 11 speed crank on my 10speed bike?

seven Posted October 26, 2018 Share Yes, as stated. Chain width is identical... Edited October 26, 2018 by seven Moooving 1 Link to comment Share on other sites More sharing options...
urbanroyal Posted October 27, 2018 Share https://www.cyclingweekly.com/news/product-news/shimano-105-r7000-vs-shimano-105-r5800-what-are-the-key-differences-374671 These guys reckon it might not work due to the inner ring of the crankset being moved.I've seen guys using an R8000 crankset with older front derailleurs . It worked but not a 100% due to the smaller ring being moved. Moooving 1 Link to comment Share on other sites More sharing options...
Butterbean Posted October 27, 2018 Share Nonsense... I'm running an 11 speed crank right now... Hell, I'm mixing and ultegra 11 speed crank with a Sram red 10 gruppo and it works beautifully. Moooving 1 Link to comment Share on other sites More sharing options...
Cippo Posted October 27, 2018 Share I would recommend to running an 11spd chain though Moooving 1 Link to comment Share on other sites More sharing options...

Zatek Posted October 27, 2018 Share Cool...is it a 6800 or R8000 crank...Just a quick question. The shifter and limit screws a deterimne the move of the chain so if the distance is smaller it should work unless the chain width might be to big but I doubt it. Assuming the distance between the teeth didn't change which is unlikely. Link to comment Share on other sites More sharing options...
Jewbacca Posted October 27, 2018 Share I use an 11 speed chain on my 1x10 speed Gravel bike. It shifts better and SRAM have made a retail price R275 11 speed chain to help us all prolong the life of our kit by making an affordable chain option. The differences are so marginal that neither you, nor your bike will know. Moooving 1 Link to comment Share on other sites More sharing options...
KurTieB Posted October 27, 2018 Share Yes. I just purchased an 11 speed Sram Red crank and have it setup with my 10 speed Sram Force. No hassles except when I sometimes go from small to big chain ring. The chain just needs to be not too high up on the cassette otherwise it takes too long to catch onto it. I therefore drop a few gears down in order for it to catch onto the big blade quicker then go lighter on the cassette if i need to. Not ideal I know but wanted to upgrade whole system but circumstances didn't allow me to, unfortunately. Link to comment Share on other sites More sharing options...
Thomo Posted October 27, 2018 Share Manufacturers will generally cover themselves by recommending that 10 and 11 spd parts not be mixed ... but most times there's no issue when doing so. Link to comment Share on other sites More sharing options...
Me rida my bicycle Posted October 28, 2018 Share The chain links are the same length the 11 is just a teny tiny bit narrower so small difference that I have fixed a buddy's 10spd chain out on the trails with a 11spd link it fits but makes the link stiff. Not sure about running a 11spd chain on a 10spd group as I have not done it but running 11spd crank with 10spd and visa versa works perfectly.

The thinner chain means there's more room Me rida my bicycle 1 Link to comment Share on other sites More sharing options...
