Things that keep me coming back to Shimano in my limited experience, the ergonomics work better for my hands, the brakes feel superior, and everything in general just feels a little more polished.

Shimano does actually produce a dropper post marketed as the "Pro Discovery" dropper. I have used on my gravel bike for 2 years and it's been flawless.

I'm just here for the JOM/BD collab intro 😆

My goodness, the last couple minutes are hilarious. Someone make this man a shifter display 🤣

Watched the whole thing without any skipping, which never happens with this type of content. This is a compliment, by the way. To my mind, 11s was/is a handicap for GRX. I’m glad to see them address it, but the the people want Di2!

Thanks for always doing a thorough, professional job.

Looking forward to seeing if the revised GRX 2x still plays well with larger cassettes. I currently run a 11-40 on my GRX 2x and having a 10-44 with a 46/30 up front would be a great climbing setup.

Love how you break everything down into digestible bites for newbs like me...thanks!!

That outro is priceless. I don't race and my fitness isn't what it should be, so I'm typically looking for low end. I like the Shimano BB design, preferably non-pressfit and T47. That stated, I've used Shimano cranks with what is otherwise Campag Ekar (9-42t, Checkpoint SL5) and SRAM AXS (10-52t, Checkpoint ALR4) drive trains with good success. The 'glue' ends up being the chain ring, which is Ratio (36t) for the Campy and Wolftooth (40t, 42t) for the SRAM. I like the Garmin power pedals with the Campag and Stages double-sided on the SRAM. I also appreciate that with a little internet research I can find 3rd party parts to mix and match to get what I need. I want this new mechanical Shimano GRX group set for my ALR4. Thanks for sharing your experiences!

BD - you are just prolific cranking out new videos these days, seems like a new one almost every day. Appreciate you keeping me up to date on all the latest and greatest, but I'm really happy with my 11 speed Di2 (2X). Don't feel like I'm missing anything, don't need 12 speed, just like I won't be looking at 750D wheels.

Those GRX levers on the bench certainly know the new trend of leaning levers at extreme angles! 😂

Come on Shimano, help us out here! Di2!!!! Another great review, Ben!

Nice to see that they are still supporting mechanical shifting. But I will stick with my 11-speed 105/Ultegra gravel setup.

Great video as always! Thanks for putting the Stages code in the description. I was needing a new power meter for my dream build I'm getting built up now.

My favorite gravel setup that I've used was GRX 46/30 with an 11-40 XT cassette. The range was great for long distance audax road rides and for steep gravel routes. Bummed Shimano didn't make an 11-40 GRX official cassette.

The Ride down that last hill was freaken awesome! 🌞

Love the addition of the blooper section.

Waiting on the full review. Hoping soon

Sorry if this has already been pointed out in the comments but I believe that it's actually the 2x option which can be accomodated by the 11 speed body and not the other way around.

the best part was the falling levers at the end lol

I was hoping this group would be available soon. I currently ride GRX one by with a Wolf Tooth 38 tooth front ring. Not having a big front ring doesn’t bother me. For the racers they can go with an Ultegra crank. I also prefer mechanical shifting. I don’t think electronic shifting makes a huge difference on the rear. For adventure riding mechanical makes for one less thing that needs charging. It’s also less expensive to replace in the event of a crash. 1 x 12 mechanical is my group of choice.

AWESOME! I often feel like an old man riding 2x 11spd Shimano GRX around Denver. That stuff just works! I have SRAM force on my road bike....SILLY! What was I thinking!

Nice to see the production upgrade, multiple camera angles and nice lighting. 👏👏👏

12:20 Apex 😉

Brian, great video and comparison to SRAM’s offerings. Loved the outtakes!!😂

Nice to see you in Bend. I instantly recognized those trails.

Eagerly awaiting a GRX 12 speed DI2.Hoping for wireless instead of less wires.

Great video! Thanks for doing this. Living in Bend, I recognize those places you were riding. Some great riding in this area.

I strongly relate with the outtakes in this video at work today. 😂

Your gear reviews are always grxat!

Great video. Really enjoyed the blooper reel at the end😂.

Love your videos Ben, keep up the good work

I never know what model of GRX is the more premium. Unlike Dura-Ace, Ultegra, 105... GRX is just all GRX and if you look at part numbers sometimes it will have a 400, 800 but even on their GRX page they don't say anything about 400,600,800. They just have how many speeds in the rear cassette and whether it is Di2 or not. I was looking at a bike at the shop and both models had GRX, I only could assume that since one bike was more expensive than the other... that GRX was "lighter?" Shimano needs to do a better branding and aesthetic distinction between their GRX tiers, because honestly it's all GRX to me.

Got tired of waiting on 12s Di2, bought an Endurace CF7 105 Di2. Guess I'll keep waiting for Di2 version. Good info.

That ending was fantastic 😂 Ill hold out until a Di2 option is available, but im happy that 12 speed is finally out. Hopefully the hoods have been made larger like the new road 12speeds, as I have very large hands and the 11speed Di2 hoods are too small

it annoys me that the don't offer a 165mm crank option in the 800 series.

Really happy with my 2 x 11 shimano GRX on my Topstone gravel bike .I can ride road events and most MTB areas .I also have Shim Di2 and sram eagle on other bikes .My best MTB groupset was also a 2 x 11 .Don,t see the need for this 1 x 12/13 setup anymore .The casettes are way to exspensive to replace .My new Shimano GRX 11 speed cassette costs 10% of a sram eagle one and i prefer to stand and cycle in a larger gear at the back and not murder a 10 cog eagle cassette .Long live Shimano 2 x 11/12

Di2 baby! I’m waiting…

Agree with the 42t 1x chainring. That will not work in local varied terrains and gradients of various lengths. Spun out 42x11 with 11-36 rear on a rival 1 setup on long descent as the group rode away. Also overgeared on the long canyon climb. So will need 2x the but rear gearing is too high from shimano to buy as is. Will have to modify the shimano gearing a bit to work for me. Or just buy sram rival axs which has what said with all the sram options. But love the new shimano wheels.

Loved the video you did a good job of presenting everything. Good enough that now my twin is interested in upgrading to this instead of MicroShift Sword.

Nice video man. If you're a one man squad props. Sick quality

Agree on chainring. When I see 40T on a gravel bike I'm like whaaaat!? I use Garbaruk rings and don't care what manufacturers do. And the time it will get to customers/builds/stock there will be plenty of options. Btw I used x12 chain on a regular chainring (x11) works fine. Try any ring you have.

Very nice video! How about the mentioned update-video? :)

Hooray for ultra-sonic cleaning.

Di2 GRX 12-speed is in the making, Shimano confirmed it.

I have been totally impressed with the HG+ shifting on XTR. Really psyched to get the 12 speed GRX 10-45 on my gravel bike, with a 44 T ring (I run a Red crank for the power meter, and aftermarket 12 speed HG+ compatible rings are available). One question: is the cable pull for the mechanical group here now the same as with the MTB stuff? If so this would allow the option of using XT or XTR derailleurs... Would be nice to know.

Mullet out of the box. Nice.

don't forget your chain catcher this time

GRX crank arm spacing is 151mm and road is 147mm.

Love the out takes.😂

I was hopping to see a 11-45 12 speed cassette with 1 tooth jumps on the 3 smallest gears. Sram released something like this in their xplr line.

Great video as always .

I was wondering if some sneaky behind-the-scenes GRX testing was going on. For an all-road bike that 48/31 with 11-36 seems like a good fit for range and cadence matching but they really should have come out of the gate with the Di2. The 1x should be at least finally comparable with SRAM, in fact besting their XPLR group unless you use a SRAM mullet setup but I think the steps are just too great to use on longer rides with mixed road or flats.

Really like Shimano stuff, especially the brakes but man do I love my new xplr axs 1x set up on my checkpoint.

I have 11 speed Shimano road, and SRAM AXS mullet and honestly, I’m leaning towards going Microshift Sword next because it’s 1/4 the price of GRX mechanical. If it was hydro it would basically be game over Shimano/SRAM in my opinion.

JOM sighting... outstanding. Not sure if the 12sp really is much more than an evolutionary step and certainly not going to rush out and retire my current GRX 800. Might help on the pricing come the next time. Thanks for the details Ben

Ben, Assuming interchangeability between road and gravel groups, do you prefer Shimano road levers or the gravel levers? I don't think I have big hands though apparently the cycling industry does, and standard hoods seem small.

So, how's 1x treating you ? I have changed recently on the gravel bike, and chose the ring size to maintain lowest gear, and had a slight drop in highest gear (no real issue) but the 2 tooth jumps really bugs me when on fast sections ... Thinking about mixing and matching with other cassetes to get smaller jumps there. I don't mind any of the other gear jumps, and as a whole 1x works better for me, as most of the time I use the middle range, so no need to change chainrings on bumpy stuff is definetly a +.

Do you know the pull ratios? Will these shifters work with the Shimano MTB 12s derailleurs?

Have you had a chance to look at the L-TWOO offerings?

Hey Ben! Off topic. Want to see you on a time adhx. I love and trust your reviews. (Got a giant revolt advance 0 on your recommendation, and it has not disappointed. I LOVE this bike!) Im always looking for the next bike, and am very interested in the adhx. Please check it out when you can 👍

What I really want is gravel 12-50(-53) cassette. A range of 10-44 but with small high gear ratio changes. I guess derailleur adjustment screws would allow for 12 tooth smallest cog.

Dang I'm waiting on parts tocdo a mechanical XPLR build. I wanted the GRX stuff but it seemed iffy as to when that would be released. Really tempted to fall back on XPLR and build a 1x GRX. I have a 2x GRX 400 bike and honestly love it so wouldn't mind sticking with Shimano

Ben, great review and honest feedback on this release. Question: is that 10-51 cassette just an XT/XTR cassette or something new specific to GRX? Also, while I appreciate 12 speeds (from Shimano) now being offered to the masses for gravel bikes, I'm sticking with 11spd GRX Di2. It's easily my favorite groupset that I've used. As well as XT is set up on my mountain bike, it's rare that I'll ride that and not wish it was Di2.

What are the shifter options for flat bar bikes? Could you speak in terms of gear range than teeth? That makes more intuitive sense.

Small correction, Shimano does have dropper posts - Tharsis, Koryak and Discover afik

I'm waiting for a new bike with this 10-51 drivetrain and the new 750x40 tires/wheels.

Seems like shimano has carved out the lower segment of gravel groups, while SRAM has the higher end. Makes sense why they only have mech for now.

a 2x mech? New touring bike groupset maybe? Should have good climbing, and be a good upgrade to a sora setup I have atm

@TheRidewithBenDelaney are you waxing chains now? (noticed the ultrasonic cleaner on your bench). Could be a good video on the practicality of doing regularly. Also isn’t that garage cold with no insulation in Boulder?

Still no post mount brake calipers! I have a Post Mount and a flat mount on my CaadX. It would be nice to buy both GRX calipers instead of an MTB caliper on the front and GRX at the rear.

Any chance we can see the route/ride course? Scenery looks beautiful 😊

Do we know if the new brake calipers are compatible with the 11spd grx brifters? Out of all the changes, the part that really perked my ears up was possible relief from rubbing chirping brakes as a big guy.

I’m hoping the new 12 speed DI2 GRX will be semi wireless

What is the point in 1x setup 40 chainrings and 51t cassette when you can go lower on a 2x setup with 46/30 and 11-40cassette? At the same time your highest gear will also be higher. What is the point?

I wonder what the gearing difference is with this new 10-51 compared to the XTR 10-51. The XTR is lighter by quite a few grams...........

Like you said the 2.5mm extra on the Q-factor on gravel groups allows wider tyres, however Shimano thinks anyone riding gravel, at least at the top tier doesn't deserve any cranks shorter than 170mm. Stupid, especially considering studies showing the benefits of shorter cranks, and of course people like my 5' 2" wife are just screwed if they want to keep a whole groupset.

any facts on cable pull specs? will the new RD's shift shimano drivetrains setup with 810 11 spd shifters?

I wish you had taken Shimano to task for only offering up to 11-36 cassette for 2X. Is that the best they can do? Why aren’t they designing it for 11-40?? The masses want wider 2X gearing (or at least the option of it) for a gravel groupset ..

Can you put Shimnao MTB derailleurs on GRX shifters (same pull ratio)? HG Free hub body no longer work with my existing I9 torch hub?

Awesome

Any insight on RD max tolerance- I ran my grx 600 46/30-10/42 no problem with a loaded bike often climbing fairly rough terrain. The 1x option looks good but I’m hesitant to let go of the 2x I often use my bike for road riding as well.

Ben, DI2…. Any ETA? In your opinion?

I really miss Bend. Watching this video reminds me of the smell of pine tree.

Is the coating on the levers different from the 11-speed version? I was not a fan of that stuff at all. Way too fragile and you can just tell in about ten years it’s gonna degrade into a sticky bummer.

It seems as though the 11-32 cassette is not made for Shimano 12 speed. This eliminates my perfect everyman gravel gearing of 46/30 and 11-32. I know 48/31 and 11-34 is very close but the cassette, chainrings and chain are heavier.

Are the brakes new from previous 11speed GRX? Also, anything other than GRX 11speed crankarm are compatible with 12speed GRX?

I feel like I'm missing something. Are there ANY wheels out there (besides these brand new Shimano ones) that have 142mm microspline hubs? How do they expect anyone to spec this on gravel bikes when their hub is only available on mountain bikes? Who can actually install this right now on a drop bar bike without having to replace their wheels? Genuinely curious.

Street price on this is about 20% higher than Ultegra Di2 street price ...

I am suprised you would choose 2x against 1x. I always thought you are a 1x guy. I may remember wrong but when you talked about giant revolt you mentioned that it's 2x and you would prefer 1x. Why did your preference changed Ben?

What is the blue bike in the background?

Shimano do dropper post options under their PRO brand. Also - isn’t the freehub for the 2x set up not the same freehub they’ve used for years? The Road 11spd HG freehub?

A few questions - Assume the cassettes are XT MTB 10-51 and 10-45 cassettes? Not sure if you explicitly said -the 2X option is 12 speed - if so I think this is a big miss that they should have an 11-40 rear for us less fit riders. Finally - is the pull on the cables the same as 12 speed MTB?

This was low hanging fruit for Shimano. Let's take our 1x Mountain bike drivetrains with 10-51 cassette and make a mechanical dropbar shifter. Shimano and Sram should have done this years ago! It's what everyone wanted. Instead they only made expensive 1x electronic drivetrains with 1x wide range cassettes so that they could milk people out of their money.

Do you really want the Shimano power meter on GRX, though? It's pretty bad.

Why do you say the rotor is new? It looks like their current second level XT MTB model… just curious.

12speed mechanical? Goodluck fine tuning that and keeping it tuned!

GRX rd with road fd and road crank 50/34 ftw

Where is that road or path at the end of the video? 🤩

The idea you are going to spin out is a little silly. 42x10 is equivalent to 52x12. So sure it’s possible, but it’s not really worth mentioning is it? 58kph at 110rpm.
