Shimano today releases its latest 12-speed MTB groupset, the SHIMANO DEORE M6100 series, alongside new 11-speed SHIMANO DEORE M5100 and 10-speed SHIMANO DEORE M4100 versions to bring premium technologies to a new price level.

 

The M6100 series is moulded from the same DNA the top tier XTR, SHIMANO DEORE XT and SLX mountain biking groupsets and is fully compatible with its more progressive companions so you can pick your favourite setup to match your riding needs.

 

Meanwhile the 11-speed and 10-speed versions build on SHIMANO DEORE’s mountain biking legacy, retaining technologies such as HG HYPERGLIDE shifting, 2-WAY RELEASE levers, SHIMANO SHADOW RD+ derailleurs and I-SPEC EV handlebar controls to broaden the versatility of this value-focused group.

 

 

Shimano DEORE M6100 Series (12-speed)


Shimano’s proven 12-speed technologies are inherent in every component at SHIMANO DEORE level.

1x12 Crankset: The SHIMANO DEORE 12-speed crankset (FC-M6100) with its sleek metallic colour shift design comes in single-only (1x12) configuration for drivetrain simplicity. It features the same DYNAMIC CHAIN ENGAGEMENT+ technology as XTR, SHIMANO DEORE XT and SLX cranksets which, with its narrow/wide tooth profile, provides the key to the improved chain retention, smoothness and quietness of the drivetrain. For secure and fast mounting of the chainring the crank is equipped with a direct mount system, making chainring changes a breeze.

Options include the choice between 170mm or 175mm crank arm lengths, 30T or 32T chainrings (although there is full compatibility between smaller or larger chainrings at SLX, XT and XTR level), or the choice between three different Q-factors (stance widths), 172mm (for an O.L.D. of 142/148mm), 178mm (O.L.D. 148mm) or 181mm (O.L.D. 157mm). Two alternative non-series SHIMANO DEORE-level cranksets are also available, the FC-MT511-1 (30T, 32T) and the FC-MT510-1 (30T, 32T, 34T). See table below for a summary:

Cassette & chain: The SHIMANO DEORE 12-speed MICROSPLINE cassette (CS-M6100) is made from 12 durable steel sprockets and comes in a 10-51T gear ratio. Complete with the unmatched shifting quality of HYPERGLIDE+ technology you can shift both up and down this cassette under load, making SHIMANO DEORE shifting smoother than ever before.

The SHIMANO DEORE 12-speed HG chain (CN-M6100) offers a smooth transmission with strong chain retention by extended portions on the end of inner chain plates to combine perfectly with DYNAMIC CHAIN ENGAGEMENT+ front chainrings and HYPERGLIDE+ cassettes to let you pedal continuously, even whilst changing gear under load.

 

Rear derailleur: The 12-speed SHIMANO DEORE rear derailleur (RD-M6100-SGS) enables precise and quick shifting within the 10-51T range. 13-tooth pulley wheels and SHIMANO SHADOW RD+ technology reduces chain chatter and gives you improved chain retention thanks to a stiffer derailleur arm and higher chain tension.

Shifter: The SHIMANO DEORE 12-speed right-side shifter (SL-M6100-IR) benefits from the same technologies as XTR, SHIMANO DEORE XT and SLX; I-SPEC EV. This offers you greater ergonomic adjustments like 14mm lateral movement and 10 degrees rotational movement so you can tailor your handlebar controls much more to your liking. Together with the speed of RAPIDFIRE PLUS and a 2-WAY RELEASE feature you can shift up and down the 12 gears of your cassette faster than ever before.

SL-M6100-IR_C219_1-d981ed-large-1586520818.jpg

 

Brakes: The SHIMANO DEORE M6100 brakes come in either an XC-specific two piston caliper (BR-M6100) or the trail/enduro four piston variant (BR-M6120), both with a redesigned brake lever (BL-M6100) resulting in a stiffer mount for better feedback and more power. The brake levers are equipped with Shimano’s proven SERVO WAVE technology which results in quicker pad/rotor engagement, improved power and a shorter free stroke. Both calipers can be used with resin or metal pads and are best used with the SM-RT64 or SM-RT54 rotors.

Completing the cockpit is an optional seat post lever, the SL-MT500. This allows riders to quickly operate the seat post without sacrificing their hand position on the grip. The SL-MT500 seat post lever comes either in a clamp band or I-SPEC EV variation for a neater handlebar set up.

 

Shimano DEORE M5100 Series (11-SPEED) And M4100 Series (10-SPEED)


The retention of a 10-speed SHIMANO DEORE series and the addition of 11-speed SHIMANO DEORE expands the versatility of the SHIMANO DEORE name as a groupset to cover many different riding styles, preferences and budgets.

DEORE_M4100_10s_1-565064-large-1586520492.jpg

 

Drivetrains: Unlike the 12-speed version, both series here retain a double drivetrain (2x11 or 2x10) option as well as single drivetrains (1x11 or 1x10). Gone are some of the advanced 12-speed shifting technologies but riders can still achieve great shifting performance with HG cassettes and HG chains, RAPIDFIRE PLUS MONO left hand shift levers and 2-WAY RELEASE performance.

FC-M5100-1_32T_C219_1-6d3a4a-large-1586520722.jpg

Riders choosing an 11-speed crankset will have the option of an 11-51T HG cassette with either a 30T or 32T single (1x11) drivetrain (FC-M5100), or a double (2x11) drivetrain in normal (FC-M5100-2) or Boost spacing (FC-M5100-B2) featuring 36T-26T chainrings and a close gear step 11-42T steel HG cassette (CS-M5100).

 

10-speed riders can pair their 1x10 chainrings (30T or 32T) with a wide range 11-46T steel HG cassette or, for the 2x10 (36-26T) set up they can also choose the close gear step 11-42T steel HG cassette (CS-M4100).

 

Derailleurs: Rear derailleurs are specific to your choice of drivetrain. The SHIMANO SHADOW RD+ RD-M5100-SGS rear derailleur is specific to 1x11 drivetrain chainlines and comes with a low-profile design to avoid damage from rocks plus a chain stabilizer to reduce chain drop and chain slap. It is designed to accommodate the lowest 51T gear on the 11-speed HG cassette. The RD-M5120-SGS rear derailleur also comes with the same SHIMANO SHADOW RD+ low profile and chain stabilizer and is designed for lowest sprockets of 42T (2x11/10-speed) or 46T (1x10-speed). A more affordable M4120-SGS SHIMANO SHADOW RD is also available for 2x11 or 2x10 drivetrains although it comes without the chain stabilizing function.

 

Front derailleurs (FD-M5100/M4100) allow for smooth, quiet and light action front shifting with optimum tyre clearance (up to 2.3” on wide rims). Both options also come in multiple mount positions (D, E or M) to suit different frame designs.

 

Shifters: Whether you choose a single or a double drivetrain the SHIMANO DEORE 10 and 11-speed shift levers (SL-M5100-IL/IR) come with I-SPEC EV positioning to give a simplified connection to brakes and dropper posts, allowing for cleaner handlebars (band-type clamps also available). On the left hand side of the bars the RAPIDFIRE PLUS MONO lever lets riders operate the front derailleur with a single thumb lever for both light and instantly responsive up and down shifting. Meanwhile the right hand side lever features an optical gear display for easily visible gear position. The lever features RAPIDFIRE PLUS speed to shift down three gears at a time whilst the 2-WAY RELEASE feature allows riders to quickly dump gears to approach climbs.

 

Brakes: At 10 and 11-speeds there is one brake lever and two caliper types (2-piston or 4-piston) available. The BL-M4100 lever is compatible with 2-piston or 4-piston caliper designs. It features an additional handlebar contact point design for a stiffer feeling and comes with quicker brake engagement and a shorter free stroke than its predecessor. The BR-MT420 4-piston caliper provides powerful stopping power for resin or metal pads, whilst the BR-MT410 2-piston caliper provides a lighter weight option (resin pad only).

 

Overview


This chart quickly shows the single drivetrain and double drivetrain options available at SHIMANO DEORE M6100, M5100 and M4100 levels.

I'm excited about this! Why am I excited about this?

Well maybe some budget 4pot brakes.

DieselnDust, May 07 2020 05:17

BaGearA, May 07 2020 05:33

BaGearA, May 07 2020 05:34

That's an affirmative on the 4potters!

Eldron, May 07 2020 05:38

Wow. Tons of trickle down tech and 3x12spd group drops by Shimano in short order. SRAM must be nipping a bit...

 

And interchangeability between the 3 - winnner winner winner!

Nick, May 07 2020 05:52

Shimano also announced flat mount MTB brakes for XC frames and no doubt riders will fit them to their (flat bar) gravel bikes too.

Flat mount brakes are the devil on XC bikes, not too sure we should be happy about this...

RiverInTheRoad, May 07 2020 07:59

Now there is no excuse to fit SRAM NX or SX to any bike, ever. Such a pity SRAM has the OEM market cornered, their budget components are terrible.

Fleming, May 07 2020 08:09

Very excited about this. My 2 year old 10sps deore has been rock solid. Haven't even changed a gear cable yet I have changed the chain.

Super Sywurm, May 07 2020 08:19

I am pondering what the price of the M6100 groupset will be.

morneS555, May 08 2020 06:05

these look so nice. proof that just because something is relatively cheap that it doesn't have to look like you bought it at the china mall....(i'm looking at you SX and NX).

You also better know that when you and your buddy both get bikes and he has SX/NX/GX on his and you have Deore on yours....that your casette wont look like absolute **** 500km into its life, thats if the derailleur doesn't explode first lol. i've never gotten why you'd want to coat a cassette in any sort of color....whether black or gold or whatever....the roadies still seem to have their heads screwed on straight in this regard.

 

edit: might also finally be time to upgrade my trusty Deore brakeset to the new 4 pot ones. Now just to convince the wife why she'd want my old ones on her bike :ph34r:

PhilipV, May 08 2020 06:26

Oooooh yeah!
4pot brakes, 11clicks and at deore price points without being SRAM. Yes please.
I'll change a freebody for this.

Me rida my bicycle, May 08 2020 06:46

This is great and but, it in the past price difference between XT, SLX and Deore was so small it never made sense to go full budget. So I am interested to see the prices.

BaGearA, May 08 2020 06:51

You could be a freehub and new cassette for less than gx a cassette if you shop around

Louis for real, May 08 2020 07:17

Thank you shimano!

Hopefully the 11 speed cassette comes in at a good weight.

The steel chainring is awesome

And deore brakes can not be beat for the money.
i have xt brakes and they feel basically the same.

Wish they would release a wide range 8 or 9 speed group.

I'd be on that like a rash

Meezo, May 08 2020 10:13

$300 according to the pinkbike review

MTB-More, May 08 2020 10:54

From looking at the current price point the cassette would be ($ converted with NO import markup) around the 2k mark... For that price I will stick to my XO1 1x11 speed as the replacement parts cost the same. 

 

Its a lot cheaper to have 2x chainrings and swap them based on the race type you are doing than to go 12 speed and has been working well for me so will stick with 1x11 as there is nothing wrong with it

T-Bob, May 08 2020 11:56

I've always loved the lower tier Shimano lists. just rock solid and unbreakable. Perfect to throw into any N+1 build or a rowdy hardtail, just forget about it and ride.

This, paired with an XT shifter....

That is a good call. Nice.

Makes sense to save a buck or 2. The shifting performance on the new 12 speed however is really something to experience.

ChrisF, May 09 2020 11:09

will the new 11 speed fit on the older hubs ?

I see Shimano these days like the iPhone crowd. Their fanclub is always out in force about how fantastic it is but in actual facts its just like the rest with new marketing campaine and a fancy new box. At the end of the day its still Shimano and 2 years behind the rest.

 

SRAM is more the allrounder as their top line XX1, XO1, XO sets dwarf what Shimano has on all fronts and then they open up the market for everyone with their plastic range on SX and XN... 

Like Android does. 

 

In comparison a 12 speed is just a 12 speed and if you cant get up that hill with the 11, 10, 9 or even 8 speed you have... Train harder, tell your legs to shut up and push though. I bet when its actually released to the public and they start riding with it there will be a host of complaints like with any other budget range. 

 

Isolated testing is very BIAS depending on how hard the sponsor pushes the "fancy" and currently only 10 ppl realisticly have tested it and gave their sponsored opinions EXACTLY the same that happened when the NX came out. Sponsor reviews cant be trusted.

Sorry, I don’t agree. I’ve got XO and XT. There ain’t 2 years difference!
