Shimano Deore M6000 derailleur which size?

[Chief Broom]

Advice please, im fitting a ten speed 11-36 cassette on my Dawes 201 [1 x] and unsure whether i need a long or medium cage Deore M6000 derailleur. I would guess the medium but dont understand some of the terminology ie max low, max teeth difference. Chainring will be 42t. Thanks

Are there two Deore M6000 derailleurs? I'm surprised as being MTB should be long. If there are two either should be okay but check on the Shimano site, bearing in mind the specs can be exceeded by a small margin.

Think the shortest cage will do the business. Capacity required (NB a 1x) is 25t.
Have no idea whether it will manage a 36t (jgi - specs), but that's not what the OP asked (and cage length irrelevant).

still scratching my noggin am i correct in thinking the long cage can take up more 'slack' and for my purposes - 11-36t cassette 42t chainring the medium cage would be most suited.

Doesn't matter what front cog you have on a 1x you only need to worry about the range on the back, as long as that is in the capacity then you're good

Agreed you want a long cage for 36 or 42 cassette surely.

According to specifications,

medium cage

• capacity: 41T (Medium GS version),
• Maximum Large Sprocket: 42T

and long cage
capacity 43t
Maximum large sprocket 36t

This is from the Spa Cycles website...

Description	Wide link Shadow design Dyna-Sys 10-speed top normal Deore rear derailleur .... GS - Compatible with 42T low sprocket (single chainring) SGS - Compatible with 36T low sprocket (double/triple chainring)

So if you're going 1x it's the GS medium cage model you want (RD-M6000-GS info on Shimano product page)

Thanks Jenkins i do like an answer thats definite
I emailed a few sellers on ebay to see if i could get a consensus...the first reply i got was "it sounds like its the right one" i can imagine a politician answering like that

 

[Cycleops]

You can't rely on the answers from sellers who are just trying to move their goods

 

[Ajax Bay]

Well apart for one chatter above, the OP got a fairly clear and accurate answer, certainly with more reliability (and some basis) than the easy sellers who responded.

Thanks folks ive ordered up a medium, the rest of the components seem straightforward, just hope they all play together nicely!
