NEW Shimano GRX 12-speed gravel group: details and ride impressions

[@shawnoen1029]

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.

[@TheRidewithBenDelaney]

Thanks for the correction.

[@lukepranger1145]

I got it too but haven’t used it yet.

[@toomaslehtonen5055]

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!

[@joelv4495]

I beg to differ. We know what they say about "opinions" but I'm pleased as punch with 2x 810 (11-40 cassette), and I could skip 12s entirely...

[@thayerkids]

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.

[@patrickseibold3829]

100%. I’d still ride late 80s dura-ace.

[@trent7919]

I agree. Having had Campy in the past, currently have SRAM Force on my road bike, and various iterations of Shimano on many different road bikes, mtb's and gravel bikes, Shimano just feels more precise and refined, better engineered, and has generally worked flawlessly over many thousands of miles. Shimano will always be my preference.

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.

[@dermitdemkuchentanzt4026]

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

[@gregskinner9210]

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!

[@thomaskuhn6541]

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.

[@industryrule-4080]

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.

[@BoxCarBoy12]

I run the same setup and love it, but with a 105 groupset. Shame that with the change to 12 speed I don't think there are any first party 11-40 12 speed cassettes you can buy

[@YannickLB]

​@@BoxCarBoy12 Why would you need 11-40 12 speed when you have a 12 speed 10-36 tup to 10-52 with a chainring starting at 30, all the way up till 56...? All you have to do is switch from brand.. Wich should be a no-brainer on gravel and mtb already..

[@BoxCarBoy12]

@@YannickLB Because I want a 2x drivetrain and I want all the low gears, even lower than 30-36t. And you can't use the 52t cassette on the 2x. And also because I have a lot of HG hubs and want to hold off on shelling out the money for microspline hubs compatible with 10t small cogs for as long as possible.

[@thedownunderverse]

@@BoxCarBoy12pretty bummed with this too. Maybe they’ll release an 11-40 HG cassette whenever Di2 gets released. 11,12,13,15,17,19,21,24,28,32,36,40 That would be sweet.

[@YannickLB]

@@BoxCarBoy12 I mean.. to each their own, but why would you want that low on gravel with 2x? Seems like a handicap. I've got 2x 12 speed 46/35 with 10-36 and in my opinion i've got all the possible range I could need as far as my imagination goes. I've done 35% climbs with it, and 80km/h without spinning out. What more is their to have?

[@thedownunderverse]

Not that I disagree, but, what do you dislike about Force on your roadie?

[@patrickseibold3829]

@@thedownunderverse I personally get a lot of chain drop shifting to my big ring. It has to be in just the right gear in my rear cog, and that changes daily. I’ve looked DEEPLY into it but no cigar. Also, I feel the ratios just are not as nice as Shimano. It’s all personal preference, and I’m probably biased as I’ve been riding Shimano for decades.

[@thedownunderverse]

@@patrickseibold3829 Agree on all counts. I’m also not a fan of toxic DOT as I wrench my own bikes. I chose 105 Di2 (with Ultegra Di2 shifters, for the Servo Wave, hood buttons, satellite ports and warm to touch lever) and it’s absolutely sublime.

Di2 baby! I’m waiting…

[@markreams3192]

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.

[@hansschotterradler3772]

38t is still big; I recently switched from 38 to 34t single ring. Guess what, I'm still not using the 11t cog.

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.

[@RaMa-vg5xn]

+ 1 on the pull ratios. Would be glorious to mix and match stuff like in the days of 9 speed.

[@kbd13-n9c]

My understanding is no…

[@nicolasrestrepoospina8878]

Same question here.... Are the new Shifters compatible with mtb rear derailleurs... It would be nice to have a XTR rear mech to save some weight and get better precision...

[@barrowsworm1226]

Further research has confirmed that GRX 12 speed mechanical is using a different cable pull ratio from Shimano MTB 12 speed system, so one must use GRX derailleurs with gRX shifters... Oh well...

[@TheRidewithBenDelaney]

Yep, as @barrowsworm1226 said, they are not compatible. From Shimano: GRX uses the Shimano road pull ratio and XTR is MTB pull ratio.

[@ebenlaubscher4153]

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

[@sccxvelo]

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.

[@emusp]

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

[@Ridingonryeandjam]

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

[@dusty_hoods]

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.

[@stevenagy7152]

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.

[@neil78]

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.

[@markxkovacic]

Perfect ratios.

[@TyTy22_]

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

[@echtogammut]

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.

[@PauloSerra]

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 +.

[@BikeLife154]

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.

[@JulianKent]

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

[@stefankucher1081]

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

Ah, good point. Thanks for calling that out. It's just not packaged as part of the GRX group.

[@stefankucher1081]

@@TheRidewithBenDelaney Nope, not specifically with GRX but e.g. Koryak has a 70mm Version for 27,2mm posts, perfect for gravel and specified by Shimano for as such (no serious mountain biker would like top be seen with either the small diameter nor the small extension according to the gnarly guys...)

[@kbd13-n9c]

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.

[@veganpotterthevegan]

11-50s are easy to find and you can throw a 12t cog on to replace the 11. As for clearing the 12t, youn may not have to adjust anything as clearing the 50 may mean you're fine on the 12 too.

[@RadCJ33]

Finally someone is saying it. Tighter range cassettes should not end on a smaller cog, they should start on a bigger one.

[@glassacre]

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.

[@TheRidewithBenDelaney]

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?

The new rotor is a CL800 with a curvy black carrier. Confusingly, I've just got the MT800s there in the video. Sorry for the confusion!

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

Call me crazy, but I'd like to pair the 2x chainrings with the 10-51 cassette. Somebody clue me into why that's not an option. We don't all have the legs of Pidcock or MVDP, you know!

[@hansschotterradler3772]

Derailleurs don't have the capacity. Assume 46/30 chain rings. That's 16t differential + 41t differential for the cassette. Makes it 57t in total differential. Too much for derailleurs.

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 ..

Is reliability an issue with SRAM?

[@WordupG]

Hasn’t been for me at all.

@@WordupG same here. 2 AXS bikes, about 15k miles so far.
