I'm sad that they're going to replace the Deore series. I think Deore has been the standard for many mountain bikers. I've been running my m5100 for 2 years now and it has been great.
My brothers bike has a M510 deore that after a jockey wheel replacement is still going strong, hoping to upgrade my bike to the 12 speed deore before its gone.
I totally agree. I also have M5100 cassette now and it is great. Before I had M4100 11-46 also great casette but M5100 has more range so that’s why I replaced it. I even use M8100 mech on it with M8000 shifter, works like a charm. I like M8100 clutch adjustment option.
@@aaivilchip my bike has always been "hybrid" or whatever, been doing it for more than 25 years. I am glad that Shimano is at least trying to make their parts a lot more cross-compatible, this should make getting parts easier whether the bike is a hybrid or not. Gravel bikes are basically hybrids, they are pretty much 90's rigid mountain bikes with drop bars.
I use my 10 speed 11-42 4100 cassette and 4120 rear mech with a friction shifter on my commuter. It needs 180 degrees of lever throw to cover the entire range. It might seem odd but the large angle of shift lever movement makes it very precise to operate.
I notice 10-11speed cassette and group set are more reliable than 12speed. The gap between cassette on 12speed is so tight meaning slight bump will change the derailleur indexing unlike with 10-11 speed not only it has smoother shifting it is more reliable as well
Your videos are always pleasant, because you have an upbeat nature. And its good to see someone speaking positively about Shimano. The components may not be flashy, whisper light, or the handiwork of extensive machining, but they get the job done.
I have a 90’s steel MTB frame I converted to a drop bar gravel bike. I was looking at Advent X, but went with 4100 11-46 & 5120 w/goatlink, shifting w/Microshift bar end shifter. I’ve really been loving it! And way cheaper than Advent X RD, cassette, and brifters.
Why add goatlink, was it not shifting properly? I have 24inch kids bike that swapped from 8 speed to 10. I got same as you M4100 11-46 and 5120 derailer but M820 for a shifter. It shifts smooth from small 11-32, some not smooth at 37 and will not go on 46.
Oddly enough, after built a m5100 groupset last week on a FS, I am looking into building a cheap HT with the m4100 groupset 2 days ago. I was wondering if the m5120 derailleur have a clutch or not. No info on shimano site/image or anywhere on web. I am so glad you did a review and answered my questions/doubts. Appreciated!
1:46 The correct term is riveted, these are rivets. Bolts are threaded in and can be removed, while rived are meant to be permanent. But Garbaruk, has the biggest cog bolted on with Torx bolts.
Another excellent video thanks. I have the 4100 10 speed set up on my Hybrid that I use to ride on the streets and paved trails. Yes you are correct it works well and is tuff as nails.
I use the m4100 10 speed on my retro bikes along with the xt shifter so you get the rapidfire plus. It works great in uk mud, 10 speed chains are more robust than 11 or 12 and are much easier to dial in the shifting
really nice drivetrain, my bike came stock with 2x10 M4100 and i converted it to 1x11 using the 11 speed deore shifter, kept the M4120 derailleur and bought 11-46 sunrace cassette and 30t deore chainring, works like charm, i even swapped pulleys for M8000 ones. the chain retention with this non-clutch derailleur is okay-ish, but once i'll definetly replace it with something with a clutch
@@LoveMTB yeah, my aluminium rigid fork is 836 grams before i cut the steerer tube to length. An 800 gram cassette is just not worth it if you're not riding an e-bike.
The M4100 brake levers are very nice levers. Lowest price (I think) point to get the EV mounts ;) Other than that, I am still on M8000 drivetrain. Works perfectly fine with 11-50 cassette. But that M5120 is interesting, if I will run out of M8000 GS spares ;D
Currently I use Deore Trekking Group set. And this is problematic to me if I use CUES. Since Trekking series is basically give you high ratio to speed up and also low ratio that good enough for road climb. I tried to count the high and low gear ratio in the current CUES, and only find closest specification when I mix Cues 10 and 11 Speed groupset. If the information is correct, CUES Rear Derailleur will compatible for different CUES speed. This is my only hope to obtain similar speed ratio with my Deore T6000
3:36 I had this cassette, I did not like the big jump between the gears. So more even jumps would be nice. The M5100 cassette is much better gearing wise, I think it even shifts smoother. But a con of the M5100 is the weight and plastic spacers, but spacers can be replaced anyway, but as they are plastic, don't fidget, fiddle with them, don't step on them. I managed to snap them using my fingers. Yes intentionally did it to test how much abuse they could take. But I had a lot of spacers on hand from the XT M8000 cs's I wore out.
@@LoveMTB so what you are saying Shimano Deore I'd being discontinued? Which will remain then? I have d1xtrail so I can use any Rd as long as it works with cassette size i use. So pull ratio won't be an issue for me.
@@LoveMTB But Deore is 12 speed. I have the Rd m6100 sgs but us eit with 11-50t Garbaruk. I guess they are going away with some of the models then. The older design with the old school link is probably going away. The m5100 sgs does same range looks the same, seem slike just same Rd apart from adding Shimano to the Deore logo. But not tried it so don't know for sure.
Some other RUclipsr mentioned the M4100 has the largest cog sitting more to the center of the wheel than the M5100, because the M5100 has a certain offset between the spider and the largest cog whereas the M4100 has not. Can you confirm this? To me it would mean the M4100 offers a better chainline, correct? I´m runnning a Garbaruk 40T chainring with 48 mm chainline and a 135 mm QR rear end. Thanks for your detailed tec info!
Excelente trabajo, muchas gracias por la información. La diferencia de precio entre el grupo 4100 y 5100 hace que me incline por el primero. Cuatro dientes de diferencia en el piñón más grande no me parecen suficientes para pagar un 25% más de precio. Excellent work, thank you very much for the information. The price difference between the 4100 and 5100 group makes me lean toward the former. Four teeth difference on the largest sprocket doesn't bother me
I am a complete component snob but bought the Giant E+ Elite 3 about 2 months ago. All of these low-end components are annoyingly excellent in use. I was looking forward to upgrading stuff, but nothing would be a substantive improvement! Oh, I did replace the DHF up front with an Assegai I already own, but otherwise, this stuff works really well.
While I do not consider myself a component snob, we alll like "nice stuff." I've always said my favorite groupsets are 9-speed mountain drivetrains. I have SRAM X-9 on one old hardtail, and Shimano Deore on a rigid GT Peace 9r. Both are 44-32-22 triples coupled to 11-34 cassettes. People may laugh, but in all honesty, the SRAM/Shimano 9-speed mountain drivetrains just W-O-R-K. The total range and jumps between gears is just hard to beat. Are they "race" bikes? Absolutely not! My modern hardtail has a Deore 11-speed drivetrain, and my 11 or 12 year old Synapse has 10-speed 105. Upgrade? I honestly can't see a reason why. The mid-grade components honestly just work too well to consider replacement. Yes the components add a bit more weight, but for even heavy recreational use, I don't feel it matters.
Before buying a bike last week I vacillated between the 2x and 1x drivetrains and ultimately chose the cheaper M4100 2x. Right out of the box the front derailleur is causing me problems. 😕 Wherever I set H/L limits the chain is rubbing on it somewhere, and the bolts for adjusting the other axis are completely obstructed by the big crank.... Pain in the ass. No wonder they started getting rid of 2x drivetrains.
I am on a brand new M5100 with 11-42 cassette from Sunshine. The shifting isn't great and I could never index it properly. The upshifts are especially painful. I have zeroed in on the cassette as the problem and have an M5100 unit coming in soon - hope it solves the issue. It is surprising because I have used numerous other Chinese cassettes and none had this problem. After many frustrating hours to index it I finally gave up and made it so that it AT LEAST shifts to smaller cogs smoothly and leave the downshifts on my thumb's expertise to push up the shifter. If Shimano cassette doesn't solve the problem, whole drivetrain is going away and be replaced by M8100 XT with SRAM PG1230 cassette soon.
@@LoveMTB just look at the shape of teeth on the inner site. IMHO (I believe it's 4 largest cogs) are shared between 5100 and m6100.They're just placed on a different spider (hg11 vs MS12). I don't own any of those but If You have m6100 cassette by chance You could compare those and let me know? I think they reuse 4 largest cogs for m5100 just for production cost savings vs. performance.
@@LoveMTB Right now I'm comparing photos of M6100 and M5100 on the internet and first 4 cogs are IMHO the same HG+ on both. 5th cog is kinda hard to say cause M5100 has drilled holes vs no holes on m6100 model. Anyway I assume it's safe to compare M5100 to any Shimano 10-51 12 speed as shape of the teeth is the same.
There is still quite a bit of 10 speed Deore out there including the T6000 trekking series triple cranksets (48,36,26) of which I have stock . I have 592 and 593 rear derailleurs (10's) as well ,.SGS .
I actually switched from deore 6100 to deore 4120 on my ATB bike packing rig. totally worth it. and you said 4120 doesn't come with a clutch... my rear mech has one, so maybe its a new thing?
@@LoveMTB the range. 6100 was my first foray into 1x and while I can see some value in it, it doesn't match the needs of my application. Korea has great bike infrastructure, but it often means some paved riding, but then we're all mountains here too. with 1x I had to compromise either my top end speed or my top end climbing. 2x10: 38/24, 11-46 get's the job done. Cheers
Pretty sure it's the same HG freehubs they use. Don't know about cog spacing but if they don't talk about thicker chains - and they don't - it should be the same. They will use 11 speed chains for this so worth testing it.

I use the 11-42! Perfect for road and gravel 1x with a 42 or 40 teeth crank at the front.
