Shimano M7100 M8100 M9100 Direct Mount Chainring Replacement

[@petterberard-andersen1485]

Very thorough and easy to follow tutorial - I just replaced my 32t SLX chainring with a 34t and the whole process was easy and went like a charm by following this video - thanks!

[@marktechsci]

Park makes the tools for this now. I just did it with them. LRT-4 lock ring tool TWB-36 Crowfoot to remove with a 3/8” breaker bar and reinstall with a torque wrench.

[@LD-bv1pm]

Many thanks, 34 now replaced with 30, now I'm gonna tackle that 24% again :)

[@Milessongs]

Thanks for yet another excellent tutorial vid! Yours are the most clear, detailed and easy to follow videos out there!

[@smithgov]

Helpful, thank you. I installed the chainring onto the crankarm not knowing I needed the lock screw to secure it. Well, there was lots of play after install so I knew I missed something. I found and watched your video, and sure enough issue fixed!

[@RJ-lp7lm]

Thanks for this detailed explanation... I installed it totally wrong but thanks to you I was able to fix the issue. Thanks a bunch mate.

[@Tommy_Teaspoon]

Thanks for posting this. I needed to change my chainring, and this was what I needed to know.

[@K2Rclan2]

Only proper video i found that explained it all. Thanks!

[@ridemore54]

[@mas465190]

thanks for the time and effort. Very informative.

[@rattshafta1820]

Great video. I'm just changing over to hollowtech from the old square tapered spigot variety. This looks so much easier and less hassle. Thanks for the video.!. I'll be subscribing

I need ANOTHER special tool for my shimano drivetrain. Annoying. 3 hex screws for the sram centerlock.

[@168grhp]

Excellent tutorial video! Thank you!

[@hoxtonloft]

Good job. Who make the adjustable spanner?

[@gavinheron1]

Great video.

[@MrPlanetmeier]

Thanks for the great video! Do you have any tips on what to do when one or more of the 8 bolts seen in 8:39 of your video come loose and are eventually being lost? Somehow I can't find anything on the internet about this at all 🧐

[@isakhaltli7323]

Hey! Did you find out anything? I’m currently in the search for the exact screws you are talking about. Nothing to find..

[@MrPlanetmeier]

@@isakhaltli7323 nothing at all … emailed Shimano and am waiting for a reply

[@marktechsci]

Per Shimano those aren’t for users. If they come loose they should warranty the part.

[@jmoney2724]

Thanks for the video. Nice to review prior to taking on the crankset swap. Curious about the portion around the 9:00 mark- I noticed there's no mention of spacers anywhere. I have an 8120 crankset with an XTR chainring on a 73 threaded bb with Boost spacing. Is there supposed to be a spacer installed (after you've done up the lockring) onto the direct mount chainring (in addition to the non-drive side spacer installed onto the bb)? Shimano installation seems to indicate so- (Ref. Page 29 of Shimano installation instructions) and two spacers were included with my XT crankset.

[@antc5010]

I'm assuming your setup is x1. With 8120's I think your chain line is 55mm and Q Factor 178. Depending on the type of BB you may need spacers. My old SLX M7120-1 with standard Shimano BB-MT800-P requires a 3mm spacer either side of the BB. I've swapped out to a M7100-1 to reduce the chain line to 52mm, matching the boost (148mm) 12 speed cassette. The change didn't require spacers and sorted the dropping of the chain on large cogs during back pedalling on techie rocky climbs.

[@jmoney2724]

Thanks. It escapes me which way I went here but it all turned out fine and yes, I'm running a 1x. @@antc5010

Nice, but i loose some of the torx bolt of my shimano slx chainring. Were can i foud new ones? (Name of the torx bolt to search) Nice work! Subscribed

[@JAM76ER]

Thank you

[@dombersot1]

Thanks, Good job

[@MKHLX]

7:44 is that knot is the same size from center lock rotors?

[@kenvysmiguel8817]

Does m7100 can be 1x and 2x? Is there spacer between chainring?

[@Badsneakers78]

Very helpful! What do you like for grease and what torque wrench is that? Thanks!

[@lucamottadelli7878]

brilliant! thanks

[@mjojrjr6231]

Is the chainring of this 3mm offset as standard or zero offset?

[@faridshoolizadeh]

Thanks

[@brutzkibrutstatte4379]

Great explanation👍🏼. Is there a specific tool for the 8 little bolts which connect the spider with the actual chainring because a few of mine came loose recently.

[@FreeToCycle]

T30 torx bit.

[@AM-yb1ez]

Do I need to remove links if I'm going from a 30t to a 36t?

[@roghax85]

hey bro, awesome video, can you help us to know what toos or how get a manual to replace de the chainring from the crankset, we are looking to remove the 8 bolts. Regards

[@marktechsci]

Old question but you don’t touch the 8 security bolts. You remove the whole thing like in this video.

[@adam1885282]

Is there a park tool version?

[@christiangabriel2620]

Hello Where can i order a new lockring for the chainring? Do someone know the partnumber?

[@thim8009]

Nice job, if your going from a 32 tooth to a 30 tooth, would you know if I need to remove a link or 2 in chain?

[@playgroundchooser]

32 to 30/34 won't need any changes.

[@lucijanojurisic297]

How do you actually remove the outter screw (11 teath) on crank arm that covers 8mm Allen screw (XTR M9100)?

[@ashrichmarco3332]

are there available bash guard for direct mount ?

[@sneakyray9160]

Where can I buy the tools that are needed? Amazon?

[@vorsprung04]

I'm unable to take the chainring off of my crank. Is there a special method for what appears to be a seized lockring?

[@keithyboyOiiOii]

Hi what’s the name of the tool to get the locking nut off so ya can get the chain ring off please?

[@FreeToCycle]

Cheers 👌

[@randy3014]

I want to buy xtr m9100 38t chainring, but im not sure if it is compatible to my slx m7100 crankset or not? I need advice thank you 😊

[@FreeToCycle]

The XTR chainring is compatible with the M7100 crank, you will also need to use the XTR lock ring.

[@FLBRGZ]

Hi, I am looking at the sigeyi power meters, the dont say if the are compatible with m6100 cranks, but they are compatible with m7100 up. Can you tell me if i can fit a m7100 chainring to the m6100 cranks, they look very similar, if they do fit I might take the risk, and try it, cheers.

[@FreeToCycle]

Yes the m7100 chainring will fit the 6100 cranks!

[@RiteshKumar-cf2yk]

Can I fit M8100 chainring on M7100 cranks. I want to fit a 36T chainring but on M7100 up to 34T is available.

[@FreeToCycle]

Yes!

[@SidiNic]

This aint to bad. Is this a hollowtech crank?

[@tenkonk]

can slx crank 7100 replace slx chainring to xtr?

[@mayleng1582]

Great thanks. If i’m going from same shimano xt 32t to 34t , do i need to add a link on chain? Whats your thoughts on that?

[@FreeToCycle]

No should be ok going up to a 34t, just check the the B screw when then chain is on the 51t to make sure it doesn’t need adjusting.

[@Chrhl01]

@@FreeToCycle is that the tool needed to disassemble crank arm from sprocket?

[@philschneider4840]

is it possible to tighten the lockring without TL-FC41 tool?

[@FreeToCycle]

No you need the correct tool to get to the specified torque!

Can you put an XTR chainring on the SLX crankset?

[@FreeToCycle]

Yes! To install the XTR chainring on an SLX crank you must use the XTR lock ring!!

[@karolisliutkevicius2223]

Thank you for this video! I know the XT crankset comes with the chainring tool, but does the SLX crankset come with it too?

[@Monosoma]

Yes. With the Shimano TL-FC41

[@168grhp]

Thank you for mentioning this! I have the XT crankset and was about to order the chainring tool. It's awesome that Shimano includes it with the cranks.

Friends i need a set from the bolts of the exact chainring on the 1x12, 3 of 8 are missing, I guess they weren't tightent enough. So I'm writing this if some of you can guide me and help me find the exact bolts on internet so i can order them.... please help!!!!!🆘🆘
