Product Data

Rear Derailleur: Shimano XT
Speed: 10 Speed
MTB: Yes

This stunning direct mount model is specifically designed for 10 speed drivetrains as it offers reliable and precise shifting with a stiff and lightweight open design. Its super low profile and direct cable routing reduces the risk of damage from trail side hazards, so you won't have to worry about rocks and tree roots while riding.

Furthermore, it uses a chain stabilising switch which reduces chain bounce in rough terrain conditions, maintaining a more stable drive and shifting experience. This is a perfect choice of a replacement for your old or worn-out existing model, so you can get back to enjoying smoother and more accurate gearing performance all over the mountain.

Shimano Deore XT M786 Shadow+ Rear Derailleur is rated 4.8 out of 5 by 60.
Rated 5 out of 5 by sean73mans from Great quality mech Always have smooth shifting with xt or slx for that matter, usually buy slx, but this was on offer.

Rated 5 out of 5 by Klulor1 from Excellent RD This is an excellent rear derailleur, with instant shifting and easy installation. Looks great on the bike too

Rated 5 out of 5 by TheGdog from Nice piece of kit, no worries. I bought this mech to replace the clapped out SLX Shadow+ originally fitted to my Whyte 905. It was a simple job to remove the chain, release the cable and fit this new one, once the chain was cleaned and replaced it was then just a matter of adjusting the travel to suit 10 speed operation. It’s great to have slick and reliable changing back even on the extreme rough stuff. If this lasts for nearly 8k miles like the SLX I shall be well pleased. A Great service from Wiggle helps to.

GS or SGS?

I've got a scott scale 760 that's currently running an xt m781 long cage (38x24 rings and an 11-36 cassette). Should I replace with the m786 long cage or medium cage and would I need to shorten the chain?
Asked by: ChipCapman
A long cage derailleur will be required.
Answered by: WiggleKris

What is the difference between the long and short cage?

I ride a giant trance 3 and need to replace mine but can't seem to find in the specs whether its a long or short cage derailleur. Cheers
Asked by: Pattyoneill
Look on the inside of your current derailleur - it will show the model number (e.g. RD-M781) and the letters GS or SGS. The GS is the shorter cage, SGS is long cage. The length of cage needed depends on the ratio spread of your gears and the amount of rear travel. On a Trance you're more than likely running an SGS (long cage).

Does this come with the adapters to fit on a non-direct mount bike?

I have a Jet 9 RDO without a direct mount
Asked by: HouseNotes
This does fit a standard derailleur hanger.
Answered by: WigglePaul

Will this fit?

The picture shows the mount to fit to a standard "old" mech hanger but the description says direct mount, which is it???
Asked by: Bobiow
This will fit to a standard mech hanger.

shimano-deore-xt-m786 - cassette upgrade?

I bought this to use on a 9 speed shimano alivio hg30 cassette assuming if it covered 10 it would do 9, it won't reach the 2 smallest sprockets however. if i upgrade to a deore 9 speed cassette would that fit the same hub? and work with the xt mech? (full 10 speed upgrade is in the pipeline but couple months away)
Asked by: Mark276
I can confirm that the Deore cassette would fit on your freehub but the dérailleur is designed to only work with 10 speed cassette's and chains as the nine speed chain will catch on the cage and damage both the cage and the chain. I hope this helps.

Can I use this with shimano 10 speed road shifters

Can I use this derailleur with shimano 10 speed road shifters e.g. Shimano 105 5700 STI
Asked by: mrsix
Not 10 spd, I think the cable pull is different. Should work with 11 spd Sti though. somersetjack

Is it possible to buy the cage section separately?

Bent the cage section of my derailleur but the rest is working fine, just looking to buy a replacement cage. Is it possible to do that?
Asked by: Duchy
Unfortunately we're unable to supply the spare parts for the derailleur, however a local bike shop may be able to order the parts especially from Shimano's Supplier directly.

Chain Suck

My bike suffers fairly badly with chain suck even though the chain/gears are in good condition. Would this derailleur help me with this problem?
Asked by: Hodgeois
There are so many reasons for chain suck it's hard to say definitively, but the stronger spring would certainly help. Check your chain alignment, front chain rings (most common cause), chain condition and lube are important too. While you are at it, check the hanger. The new Shimano XT is absolutely awesome - adding that "clutch" makes the spring tension much better and yes, would reduce chain suck.

would this fit onto my 2010 specialized camber 10 speed and does it come with fitting brackets

Asked by: phil11
I can confirm that it will come with the fixing bracket and it should be compatible with your 2010 specialized camber.

what accessories come with this
Asked by: phil11
I can confirm that this would be compatible with your bike. This item does not come with any additional brackets or accessories I'm afraid.
