Shimano XTR 12 Speed Derailleur vs SRAM Eagle Rear Derailleur - M9100

[@evertonsilva-ne9bo]

Best (RD) XTR's video at the moment!

[@xxxxxx6337]

definitely. however, I was missing information. would like to know how far each one is reaching out the when mounted on the frame and how much clearance they have from the bottom when mounted on a frame

[@theodoredarian7889]

I know I am kinda off topic but do anybody know a good site to stream new tv shows online ?

5:23 - Note that the tension pulley on the Shimano derailleur is covered by the cage plates to a greater angle then the SRAM one. So in effect chain will be guided by those plates much more then on SRAM mech. I gather that SRAM gets similar effect using N/W profile on the tension pulley. EDIT: This bent on the cage _is_ intentional. The return run from the tension pulley to the chainring is very short when running on the big rear cog and on 12 speed that also means very, very hardcore angle of approach for the pulley. That in turn makes drivetrain noisy and causes excessive wear on the pulley. Offsetting the lower pulley makes this problem less apparent. I'll make a video about it, methinks.

[@WorldwideCyclery]

The review everyone was waiting for!

[@piciu256]

This bend in the cage is definitely intentional, once you install (or just look at another 1x drivetrain) you will notice how it would route the chain nicely along the sprocket, in both extremes of the chainline, that means you don't need the narrow wide profile of the jockey teeth, it's not really needed in general, but it helps with durability (I run 1x11 and when the lower jockey wheel is worn, and it wears pretty fast with those chainlines, the chain tends to climb onto it, aspecially in muddy conditions)

[@radred512]

Just ran across your review doing some 12 speed MTB compatibility research. Thank you for the excellent detailed review and outstanding camera work!!!

[@mtbsavant5414]

As a long time Shimano fan I'm so glad to see them in the 12 speed game. Looking forward to your full long term review.

[@jonienglish3231]

Shimano need to ADD a LOCK like Sram to hold the CAGE and Release Tension for Wheel Change .

[@phosphorbetamania]

and put more grams? nahh

[@seanhornchek6440]

it helps a lot, same grams somewhere else - like getting rid of the clutch lever

[@jonienglish3231]

@@seanhornchek6440 HECK _ Just get ridof clutch all together , MAke it Regular Derailleur even lighter

[@jonathankingstone3031]

Agree with this 100%. Hard to go back after using Sram's cage lock - wheel changes are SO much easier it's not even close

[@jtsimaras]

Only thing I dislike about my Xtr setup

[@albertmanzo9510]

Great comparison!! NO one beats the champ ...XTR!!

[@iancanuckistan2244]

Concise review, you always do a thorough job. Nice Joyride sicker on your scale!

[@superlongman]

I also noticed it after installing my M9100-SGS. It looks odd but the shifting is perfect, all cogs one by one. I was worried about whether my derailleur was a defect. Thanks for sharing, I'm relieved to know it's the design. I wanted to ask my friends about this but nobody has new XTR yet.

[@razorree]

did you measure Sram offset correctly? looks like 0 on a ruler is not on a bolt center ....

[@Will_i_am10]

good day sir! the same goes for the rd of the shimano deore m6100. also tilt the pulley cage

[@MTBfixHQ]

The bend would help to keep the derailleur a little further from the spokes :)

[@MoiPloy]

i ran into a bike shop to check it out and seems the cage is really bent

[@Silkl4sh]

Its cause big cogs bend cages themselves.

[@orjankarlsson9108]

Yes have a Slx 12 Speed same bend on that

[@fra93ilgrande]

Same here, on a Deore XT

[@gervaciosantos8331]

My new XTR 9100 GS RD also has that slight bend that you were talking about. I guess its a factory design???

[@LoveMTB]

Yup have a whole video about it - Shimano Cage BENT and Twisted 12 Speed ??? XTR/XT/SLX/Deore Derailleurs - M9100, M8100, M7100, M6100 kzbin.info/www/bejne/aXfLcpuYaaZ-j8k

[@JeffWagen]

Please take a look on how much the derailleur sticks out of the frame after you install it, Shimano always had the advantage of the shadow profile but this one appears to be way more bulky. Thanks sir, great video as always.

[@MrDjindian]

Starting to think I should run the XTR M9100 GS cage derailleur instead of the SGS for better clearance. My thought is to pair it up with a E13 11-46 cassette, until the shimano 11-45 12spd cassette comes out... with a 30t chain ring as opposed to my original idea of SGS with eagle 50 and a 32t chainring. Thoughts? How much more effort would the 30t-46t make as opposed to the 32t-50t when climbing...?

[@robinbreeds9217]

I am so glad all this is on line, i never used Sram before, i want to change to XTR Derailleur on the back and still use the Sram Cassette, there are already XT brakes on the Rocky Mountains i have am thinking of taking them to XTR 12 speed on the hardtail from the 11speed they came with, i have always been Shimano on all my bikes hard tail or full sust, i like the other videos you show it working

[@onilovni1234]

Can't wait for the Di2 version, I'll just have to sell one of my bike for it. Nice review.

[@andrewrockwell1086]

Really enjoy your in-depth look at this! I just got my identical XTR derailleur in the mail yesterday....looking forward to testing it out; however I'm waiting for Lindarets/Wolftooth to come up with an adapter to use my 9100 i-Spec EV shifter with M8000 brake levers.... I gambled on the fact that they'll come out with one, rather than buying the clamp-on version :P

[@derekhuber7239]

It might do with the shadow plus part of the derailleur to keep it closer to the rim I'll see if my XT derailleur is the same

[@RAUL-iz9lt]

What do you think about EAGLE 12s derailleur + Garbaruk 10-50 11s cassette + Shifter XTR 11s?? Will this work?

[@kianery]

Nice review, but I like Sram (xo1) shifter than the old xtr. Sram feels smoother and lighter shifting, how is the feel xtr 12 vs the xtr old one? Just curious!

[@zyoungson215]

Interested in this aswell

[@thermal868]

I noticed delta on my Deore, on XT and XTR all have that delta angle. Like you said it's some kind od new feature they put on this series.

[@thermal868]

@@LoveMTB It does.

[@NoBrakes23]

I wonder if my 10 speed Saint shifter or my 10 speed XT shifter would work with my 12 speed XT RD and a 12 speed cassette?

[@gbmtb187]

Do you know the part number for the little plastic sleeve that the cable goes through towards the pinch bolt? Cheers.

[@dereklawrencenitrogen_junk8168]

Do you think the 12 speed derailleur will work with 11 spd drive train ?

[@zyoungson215]

Thanks for the in depth review, cant wait to get one of these so I can get rid of my flogged out old eagle mech

[@karenstock8055]

These Eagle GX mechs catch every stick in the bush. Constantly stopping for removal.

[@imanayAieR]

the cage bend(pulley offset) are in the road series too, i first notice my R8000 after traveling, freaked me out thinking the airport dmg my rd but after check with the shop, it seem all their R8000 RD cage are slightly bend too.... it seem help to reduce cross chain when on the smaller chainring+small cogs(silent), but hell its noisy when on the large chainring.

[@alvarezherrera666]

yup yup, we all wanna go around the dedicated scylense microspline hub/cassette

[@andrewrockwell1086]

I'm also intending to run this setup, as I dont want to have to buy a microspline compatible hub....plus I think the eagle cassette has proven its durability.

[@derekhuber7239]

Yeah for 500 bucks a cassette sunrace is 100

[@andrewrockwell1086]

I agree they’re ludicrously expensive, but they’re crazy light, they shift well, and they last a loooooong time. Not sure Sunrace can make any of those claims... they offer a product with a similar function, but it occupies a completely different part of the market IMHO.

[@th_js]

How about the clutch? Is it as maintenance requiring as some of the older Shimano clutches? And awesome video as always!!

[@jonienglish3231]

Good Break Down and Review Question ? on the Guide Pulley and Tension Pulley - Any side to side Play ? on the older Shimano the Guide had lots of side to side play .

[@Tullebukk75]

No play on 10/11 speed Shimano. 9 speed and older had play.

[@lperezdav]

if I get a rear derrailour sgs 45 T will it work with a 51 t cassette?

[@elffiearshad4846]

Hi there,could you use m9120 sgs on 51t cassette?

[@art3m_t1mofeev]

As I commented in previous video, could you please try coupling M9100 der+shifter with some old 11sp cassette? I wonder if this will work.

[@alemaofloripa]

Please make a video of M9100 with a old one 11-50 11speed and shifter, for example a Xt m8000.

[@andreasmagli9862]

Hi, i have an xtr 9000 2/11 and i would like to mount it a a single chain ring. Since i m not super strong , i would need a 50 teeth cog for the climbs, a 46 teeth would probably not be enough for me. What would be my best option to mount this? And I have an other question, if i mount a oval chain ring on a sram 1 by 12 gx, is that going to bust the derailleur clutch? Thank u very much in advance. I found your videos very helpful and interesting.

[@callumgordon11]

works seamlessly with sram cassette and chain as well. much better upgrade from the horrible sram derailleurs

[@johannesheinonen9677]

My new m9100 RD has the same bend. Intended from Shimano :)

Hi! I have a question, i just bought a new bike with xtr 12 speed rear derailleur and xt 8100 cassette and while shifting gears uphill, it makes loud grinding noise. What causes this?

[@vlat18]

@@LoveMTB my friend tried to ride my bike and he said that his bike dont do noises like that but he got 400 euros cheap bike and i have 5,6k worth one. Maybe its the drivetrain what causes that.

[@gebhardt2]

Yes. The Ultegra 6870 Di2 Rear Mech cage is also bent in the same fashion. I bent mine back. I believe it is a bad design even if it is intentional. No mech manufacturer ever has done such a thing. It doesn't make sense to me. Shimano better answer this question and it better be good.

[@_systemd]

my handlebars came bent in bunch of directions, I straightened them.

[@bradcomis1066]

Campagnolo derailleurs also have a cage with a bend. Perhaps it is quite common.

I wish they would hurry and bring XT 12 speed and let me use on any wheels i want...

[@paradox963]

Really Shimano 3 different derailleurs. I can mix and match every version of eagle and it all works, Shimano you need to change the rear mech if you want a different cassette.

[@tamasvarga67]

Thank you for showing this, interesting to see that the dimensions are the same between SRAM and Shimano. I think because of the enormous pizza plate big cog there is no other choice. I had GX Eagle and I found it absolutely terrible on a 27,5 bike, the cage almost touched the ground catch everything and even the grass could bend it. I upgraded it to 11 speed XT and the difference is night and day. I rather train harder and get stronger than buying 12 speed again... 😀

Actually right now eagle is n1, I mean market say that. I'll compare both soon.
