Very detailed video! Thank you for this.. been using that 5100 crank for about a couple of years now without issues. Was planning to upgrade to the 7100 slx cranks but keep my 11spd 5100rd and m8000 shifter. Didn't realize that slx 12 spd chainring might have problems if I used it with the 11spd rd/cogs.
I'm brand new to "upgrading/servicing etc" a few weeks ago I spoke to someone at Sheffield Decathlon who worked at the bikeshop and he information bombed me when I was looking for a new suntour crankset as my pedal had fell off and couldn't find any online as I thought I needed the exact same one, he explained so many options and showed me examples of what people used for trail riding and the huge cassettes which I didn't know was a thing etc. So when i got home i researched.. alot. My voodoo hoodoo was a 3x9 shimano alivio groupset but now i run a 1x11s (11-51t) deore m5100 groupset, 32teeth 175mm crankset using a bb52 bottom bracket, a 150mm dropper seat I internally routed by drilling my frame once, new brake pads and I bled my own brakes and fitted the groupset.. I also replaced my freehub as that had massive play. I replaced both bearings and bearing cups in my headset along with the crown race and opted for new sealed bearings and better cups.. isn't the Internet a wonderful place for newbies like me to do everything! Last month I thought a bike was a bike. Now I feel like I know so much! Haha. Hardest part was the rear derailleur adjustment BUT I recently bought a bike stand for £30 and it took me 1 try to dial it in today, having to either flip the bike over or lift the bike to pedal it to adjust a derailleur is so hard as a newbie. Thanks for reading, I felt like sharing haha.
Got myself a FC-M4100-2, it's a regular chain line out of the box. Sold the 36/26 chainrings, replaced with narrow-wide. Works great and it's a bargain.
I've been running Shimano M5100 groupset for about 1 year now. No problems. Just wish Shimano did not abandon non-boost chain lines. I was able to reduce chain line from 52mm to 49.5mm by swapping one 2.5mm bb spacer to non-drive side. I have also used chainring spacers with longer 16mm chainring bolts to reduce chain line. I recently purchased SRAM SX DUB crankset for another budget build that I plan to pair with M5100 cassette/Derailleur. Honestly the SRAM SX DUB crank is little lighter than the M5100 crank, has direct mount chainring and offered in chainrings offsets for non-boost (49mm) and boost (52mm). Seems like SRAM did their homework with the DUB system. Hopefully the 28.99 aluminum spindle holds up as well as Shimano's 24mm steel spindle.
Running 5100 on my 1 X Shimano 105 commuter mtb. Irish coas here, so didn't want hollow tech as possible failure due to water ingress over time. Weight penalty is minimal. Running a 36t TA Specialties chainring. Very solid.
Great pickup about old 135mm and 142mm through axle non-boost chainlines. I've found the cheapest option for a correct chainline, is to find an old 3x (NOT 2x) shimano crank from the 9 speed or 10 speed days with 104BCD. Then install a wolftooth etc narrow/wide chainring on the middle mount. This gives a perfect 49mm chainline. You can buy both 10/11 or 12 speed chainring options in alloy and steel from wolftooth or others.
As always great and most informative video. The best on RU-vid for sure. I went Deore 12 speed on my recent build and they work excellent for me. How has the riding been this season so far?
I am testing a 5100 cassette on my 2018 Trance with an SLX 11 speed drive just to get that better 51 tooth climbing gear, and so far I like it. Just a bit more weight in specs but I really only notice the better climbing and not the weight at all.
I have the 5100 cranks on my 1x conversion. Was actually available at the time and a bit cheaper. No problems with 141 boost using the BB spacer/s. I used MT800 BB as preferred black to grey. Sunrace 11-51 cassette, but also have a Shimano 5100 to try with second wheel. Thinking 34 tooth front for more on road downhill speed too.
Starting from SLX Shimano provides stainless steel bolts in many of their parts, which is another bonus when spending bit more. Especially as you do need to service cranks, thus using crank arm bolts on regular basis. Same goes in rear derailleur, where small allen key needs nice, u corroded allen head, not to strip it. Although adjustment doesn't require much torque
My 5100 crank arm fell off my brand new bike after 2 weeks of use. I got it on and re tightened. Looked like no damage to the splines. I'm just hoping whoever assembled my bike just did it wrong and it's not a sign of things to come.
Engineering and materials science does not lie. I like an all steel 11 speed rear cluster and front chainring or chainrings they last very well. The great thing about the M5100 is it was designed for a single and double front chainring. The M5100 rear derailleur has jockey wheels that can be upgraded to XTR bearing jockey wheels and also has a clutch. The latest Deore equipment has all bases covered for reliable long lasting performance.... The move to 12 speed has not been well liked by many people for good reason. The 10 to 51 rear cluster holds no interest for me. Once you start using exotic and light weight materials and make things thinner and much lighter the life of the drivetrain is reduced which is okay if you replace parts all the time. But for the normal rider a half a kg weight reduction in not relavent but a reliable long life is.....
I have a Deore m5100 175mm lenght now. Am i able to change out the crankarms/chain ring to a shorter one without having to replace the rear Derailleur, group set etc? Im finding the length too long. And would like to try something in the 165mm range. Please forgive if this is a Newbie question.
Hi from Puerto Rico 🇵🇷🇵🇷do you know the difference between SLX an XT maybe SLX with aluminum chainrings and bolts weights the same. Thanks for sharing 👍
Hi! Do you know if exists a tool with the accuracy specific for measuring chain line? (i.e. 49.0 +/- 0.1 mm) I have a calibrated Mitutoyo caliber but the result of the mesurement is influenced by the alignment of caliber, error and uncertainment from the calibration certificade and assuming that the hole under the frame is the middle line. Always super interesting content. Thanks and regards from Argentina.
Still running the 600 series Deore 2x10 on my old devinci hardtail. Not as light as the better ones, but good value and reliable , good enough to get 6th place in the Paris 2 Ancaster Gravel race ( on a mountain bike, clydesdale category) :)
I just ordered m6100 upgrade kit and i totally forgot that its microspline and and i cant decide if i should get a new hub or should i just get another 12s hg cassette. Any suggestions?
I have a 2022 Marlin 6 and ordered the Shimano M5100 Crank, a 32T chainring and a Saint BB80B Hollowtech II. It seems the chainline will be 52cm. How do I know my original chainline? Its the 135 O.LD. QR with the Deore 10 speed. Do I need spacers?

Is there a chainring compatible with the 5100 that is larger than the 36 tooth? 42 or 46, 36 is not enough for me.
But will the pedals fall off? I saw it happen on the these Deore M5100/ M6100 cranks, A dude with a polygon had it happen, but he blamed himself, but I doubt it was his fault, I've had the same issue on two sets of M552 cranks from several years before. that's what you get if you use cheesenium alloy I don't remember the name of his channel. It happen on left side on one and right side on the other, but I combined them into one so I could continue riding, but I bent the spider. I am not a fan of a spider as a part of the crank arm it self.
@@LoveMTB I got my 165 second hand, but bought one before in 175mm years ago, for about half price. Second han done even cheaper. But I've not seen them in stock in Norway anymore. I also have turbine, lighter, but bit flexier, but good cranks. Only thing I don't like is the plastic preloader so have Cane Creek preload ring. Smooth, does not round off as easily.
Are you saying the pedal threads were stripped? I saw a video where the entire arm came off the spindle but I don't think the user had the arm properly secured from the start. I've been running the M5100-1 crank for over a year with no problems.
@@mtbbiker6401 The guy thought the overtightened the pedal, resulting in failure, But I doubt that he managed to do that I guess it could be due to ridding with loose pedals, but In my case it definitely was not any if the potential user errors. I've not had this issue with Race Face Turbine, Atlas, been using them for several years, no problem.
i was running the new deore m615 brakes and there good....not bike park good but good enough on the second bike, the trickle down tech that shimano offers makes Deore or SLX good enough for 99% of mtb'ers it's mostly marketing that puts people off buying those group/parts, i've no issue running slx cranks .....switched the deore 615 out for the hope for the trip i'm taking shimano have lowered the price of there xt 8000 range in uk.....there's new stuff on the way, think i seen somewhere it's a colour change...there making a steel/grey look range
Great video, I need your assistance, Can you help me out ? I'm in a dilemma trying to upgrade my bike from 10 speed to 12 speed Shimano. Can I use same cranks M5100 with a 32t 12 speed chainring? I just want to replace the old 10 speed 32 chainring for a new new 12 speed 32 chainring using the same cranks.. thanks in advance for your help.
Yes, you can fit a 12s chain ring on the M5100. I don't think Shimano sells a 12s one with the weird asymmetrical design, but there's 3rd party ones available.
Just the video i was looking for. I have a '22 Trek Marlin 7 and wanted to upgrade the crank to a 32t. From your video it appears that Deore M5100 crank would fit my 10speed cassette just fine. Since my frame is 135mm (non-boost) i would need to use the 3mm spacers, correct? Since my current crank is a 3 peace, that means i would need to change the BB to the Shimano SM-BB52?
@@LoveMTB could you help me out I can't find any based on thumbnail or title? I'm curious because I want to grab a 12s kmc chain for my 11s conversion (can't find any 11s chans rn). I saw a lot of people say 12s chain would work just fine maybe even better on 11s cassette
Hi, thanks for this video, very helpful. I was actually looking to replace my 32t chainring on my Shimano Deore 10 speed to a 30t to make it a little easier going up techie hills. Do you have any recommendations on budget friendly but good chainrings that are compatible?
@@LoveMTB they're only a year old, wait till you've ridden in the rain for 3years putting down 1000 watt sprints. You can find hundreds of pictures of the ultegra versions splitting then snapping
This is mostly an issue with Ultegra and Dura-drace drive side cranks and mostly the new series, because the integrated spider is also hollow on those, it never happens with 105 or Tiagra. MTB cranks are stronger and have a separate spider/DM . It does suck that Shimano seem to be kind of brushing off the issue with the new road cranks as "rare occurrences" though.
I need some help, I have a 2021 Giant Talon 1 10 speed with a 30T and I like to change my crankset to an upgraded 10 speed 30 T model like an XT or what you think i should get can you help me get all the right parts so I could order what I need ? I would really appreciate it. Thank you
Getting an XT 10 Speed crank today is really diffilcult, especially because you would only find 12 speed chainrings which aren't compatible with you chain. The best thing you could do is to buy the m5100 cranks that work with 10 and 11 speed chains.
Not quite if you plan on using the 12s chain which you should, I have a video about chainrings here - Garbaruk, 5dev, absoluteBlack - Top 5 REASONS to use 3rd Party Chainrings vs Shimano and SRAM ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eQIro27Ar6k.html
Casi idéntico. Éste es parte de la serie M6100 de 12 velocidades, el M5100 es de 11 velocidades. Por lo demás probablemente idéntico menos los elementos gráficos.
Are the Shimano 12s cranks really not compatible with non-boost frames? Or are there other shimano-compatible direct mount chainrings available with the correct Chainline?
Probably not relevant for you anymore, but yes, with 3rd party chain rings. I'm running a 1x12 using an M5100 and 36T chain ring. 36T because it's an older frame with uses 26" wheels and M5100 because I needed the ability to modify the chain line to fit the older 135mm QR frame width.
@@LoveMTB most people are not serious mountain bikers. 99.9% of mountain bike use is by people commuting or traveling on roads or dirt paths. And many people ride their bikes in very cold winters.
@@LoveMTB I see. Well, I don't argue with you, but it still seems stupid 🙂 it would cost nothing, weigh nothing, and it avoids the hassles of using those Velcro straps to bind your pants legs. Thank you for your reply 👍
@@LoveMTB 40t chainrings do exist that has the same bcd as the m5100 crank but that its not a shimano chainring, so my question is can I put a 40t chainring on the m5100 crank? Will it hit the crank arm since its big?
thanks i am thinking i will upgrade my super old 26 mountain bike from 9 speed to 1x11 or 1x10 but with current availability i dont know what to choose ... maybe even 12 speed non boost crank so i can reuse it later in life :D but thanks for videos they are very insightfull
