Shimano 10 speed MTB/Road cassette compatibility
 

Does anyone know if the Shimano 10 speed road and MTB cassettes have the same sprocket spacing? I know the shifters and derailleurs are not interchangeable between road and MTB, but are the cassettes?

yes they do..

There are workarounds, I have this Tanpan ? wolftoothcomponents.com works well

From 6 to 10 speeds, MTB and road cassette is just a marketing term, explaining intended use (influences sprocket teeth number range - MTB ones usually go to as high as 36 teeth). They are 100% compatible. Wrote in detail here, what goes with what (pitch, spacing, sprocket thickness, compatibility):

2) Bicycle cassette compatibility - Cycle Gremlin

Maybe a few years ago, going to 42t for a 10 speed is normal now, 50t for a 12 speed is standard

Yeah for 1x10 or 1x11 drivetrains where those huge cogs are needed to get a sufficiently low gear, at the expense of BIG gaps in the interior gearing. They are still very unusual for 2x10 or 3x10 or 11 road and most MTB drivetrains.

Its mentioned that 6-10sp have the same spacing. I use a SRAM 11sp cassette thats 11-36 and run it with a 105 11sp shifting. Works fine. Just wanted to add that in since its 11sp.

With the exception of Suntour Ultra 6 speed being the same as 7 speed, you are totally wrong.

Add to that, when talking about cassettes, the 6 speed was was so short lived, the for almost all riders, they will have never heard/come across/used it. Even 7 speed on it's dedicated hub spacing was short lived.

11 speed is not compatible in road-MTB combination.

SRAM road 11 speed has almost the same spacing as Shimano road 11 speed.
For MTB they are both identical.

However, combining 11 speed MTB cassette with 11 speed road shifters won't work well (same as vice-versa combination).

Sure - though still expensive, exotic and won't work with most road RDs without some modifications.

These 5 things combined equal exact shifts all thru the 11 cogs and 2 chain rings. Not sure why this combo works...is the SRAM cassette not an MTB cassette?...i just assumed it was due to the wide gear ratio.

Expensive - no, they are just standard parts now (for Shimano, for expensive, see SRAM XD cassettes) (go back 18 months and you were correct)

Exotic - no, they are just standard parts now (go back 18 months and you were correct)

Won't work with road RD's - they will if your running 1x and a RD with the correct t count

I believe the cassettes have the same spacing. The difference is that an 11s MTB cassette fits on a standard 8/9/10 hub.

11 speed MTB spacing is 3.9 mm for both SRAM and Shimano.

For road 11 speed it's 3.72 for SRAM and almost exact 3.74 for Shimano.

I stand corrected. Thanks for the post. :)

Shifters and RD are Shimano road compatible, but the cassette is a MTB one. Spacing is off from road 11 speed by 0.16 mm, which should result in about 1.5 mm "miss" after 9 shifts. Inner roller width of a chain is about 2.4 mm. So guess it doesn't miss enough to really bother shifting, though it's not a perfect match. :foo:

Prices here in Europe.

11-36 just under 30 euros:

Wow, thats really interesting and something I didnt look into when selecting components for the build. I dumb lucked into it working!
It was a kludge job(albeit a nicely spec'd one) to begin with since I was looking to use 105 components and a large cassette to get better bailout gearing. At least it lucked into working.





edited- I did some reading, and it looks like the SRAM cassette I have is a road cassette, even though the gearing range is wide. https://www.sram.com/sram/road/produ...130-cassette-0
SRAM recommends, on their site, using it with the Rival 22 group which is a road group. That would explain why it works well with my 105 5800 setup.

Terrible comparison as not like for like, but low vs high end; low end Shimano (HG50) vs high end aftermarket Praxis; try Shimano XT (771 11-36) level vs Sunrace equivalent (MS3 11-42) and there is about a 10-15% price difference between street prices

I agree - different class equipment. However, where I live, over 36 is still expensive and exotic, unfortunately.
