x 2, 10 vs 11 speed, quick Q

Coming into the road genre i am having some challenges understanding the difference and therefore what set up to go for. What exactly constitutes an 11 speed drivetrain vs a 10 speed one and are they interchangeable? Is it the chain disc sizes this boils down to or the cassette or is it the chain itself or frame compatibility? Looked around for a 10 speed Ultegra 8000 crankset with a 50/34 crank but these all seemed to be 11 speed. Don`t know what is so special about the 8000 series either. I know very little about 11 speed so i tend to look for 10 speed stuff. Any little clue helps

10 or 11 refers to the number of cogs on the cassette. The last 2 generations of Ultegra components, 6800 and 8000 are 11 speed. Earlier out of production generations, 6600 and 6700 were 10 speed. The only current Shimano 10 speed group of components is Tiagra 4700

I realize the part with the number of cogs on the cassette being either 8, 9, 10, or 11 etc. but not so much for compatibility issues and for that matter non compatibility issues.
So in keeping with todays "modern standards" i would do wise in choosing an 11 speed drivetrain or stand the chance of being made to look like some vintage freak?

As the 'Speeds' Upselling, goes higher in number the width of the chain got narrower to fit the tighter spacing.

But Wholesalers to bike shops carry replacement parts , for the bike components that the companies have moved on from..

To keep what you bought, before, working...

many online sellers are just dealing with the latest things..

What are you trying to do?

If you want an overall compatibility chart, you can probably find one at Shimano. If you ahve a bike with certain parts and need to update one or two of them and want to know specifically what you can or can't use then ask that question. Your original post is too broad to really answer.

I am trying to determine what speed drivetrain to go for. 9 is not an option for me so it`s either a 10 or 11 speed. 11 is such a big number for me so i need some confirmation this is what i should get

I have experience using 10 speed but not 11 speed, so i know very little about 11 speed and how this works but it seems to me this is what most road bikes come with these days. It`s not so much about compatibility issues but rather incompatibility issues and what absolutely not to buy in conjunction with eachother. I believe i am looking for a 46/36T crankset together with a suitable cassette but i don`t know what size cassette to merge with 46/36T and if these ratios are found on both 10 & 11 speed. I suppose the odd and uneven numbers get confusing. Anyway my simple reasoning is this. Buy the specific speed/size crankset first and figure out the rest afterwards. I have no idea what FD/RD to get for this set up, but thankfully i do know there is such a thing as a short, mid and long cage der. but which one fits what, no idea whatsoever. For the record by now i think i am leaning in the direction of some type of 11 speed drivetrain since i get the impression 9 and 10 is getting old.

Plus, you need both another shifter on the bars + the cassette.

Very many Nkr to be spent..

It is the Gear Ratio that, to me, matters, not upselling to the latest kit..
for more sprockets packed ever closer together..


in Bike shop repair chain of supplies lie a lot of the previous parts, to keep bikes on the road and trails, thanks to wholesale distributors ..

Not about to go into all the ins and outs of what 10 and 11 speed things are interchangeable, but I can tell you that you can use an 11 speed crankset with an otherwise 10 speed drivetrain no problem.

I actually work at a bikeshop but it`s only part time and i`ve only been there for 4 months so i still have a lot to learn. Were very busy on the job so not a lot of time to go into all the details. As i`m new i don`t get to do any repairs yet, just assembling new bikes which isn`t exactly super enlightening. I was hoping i could supply some odds and ends in here which would speed up my learning curve. By chance i read a review of the new soon to be released Shimano 105 R-7000 groupset. As for the rear derailleur, it says that the short cage (SS) is intended for the 11-25 to 11-30 size cassettes and the medium cage (GS) 11-28 to 11-34 cassettes. I was wondering what GS and SS implied, and well now i know. Didn`t say anything about any long cage though but i am lead to believe (fancy term eh) this is for bigger 36T cassettes if there is such a thing. IDK.

Read all about it why don`t you :

https://www.bikeradar.com/road/news/...details-52035/

I like the term "trickled down technology" but i don`t enjoy reading about 6800 cranksets that start to disintegrate between the metal and the exterior composite/plastic cover so i will probably go for the newer duralumin 8000 crankset.

After doing some more thinking, i am again more inclined to buying a 10 speed set up but then again i can`t because the new 8000 series only caters for 11 speed. I realize 10 and 11 both will fit on most wheelset freehubs but the miniscule differences seem obscure to me. Is there a difference in lenght of the chains or are they all the same length between the links or just not the same thickness/width? I feel i have to go into the small details to see the big picture here.
