GRX Goes 12-Speed! | New Shimano GRX RX820 First Look

[@yumyumhungry]

Wish they allowed for a proper 1x mullet dropping the chainring down to 32-36. 40t is waaaay too much for bikepacking. Even the pros have a 20 gear inch granny.

[@erlendsteren9466]

I would like 42 in front and 10-51 behind with 44 mm graveltyres. 40 + 11-42 is what I have and it is covering everything important, but I could be happy with one more gear in both ends. 40- 42 is average 7,5 km/t when going as easy as I can in long (30 minute)8% climbs.

[@Amerigo73]

Coming from a Shimano XT 3x8 GT Zaskar mountainbike from 1998, the GRX 1x12 is just the sweet spot for me. No more problems with a derailleur. I love it. The simplicity, and ease of use is amazing.

[@swray2112]

INSANE that their cranks start at 170mm considering the recent trend and studies showing the benefits of shorter crank arms in general, but it leaves people like my 5' 2" wife looking elsewhere for cranks. Other hollowtech II cranks have avaible shorter lengths, so it's not the technology. It's literally like they are trying to kill the 24m spindle or care only about OEM , knowing bike shops will swap on their small frames at the point of purchase.

Nice new gear for my next new bike, but my 4 year old bike with a few updates (lower gearing, 25mm internal width rims)...I'm set.

I'd like to try this on a pure gravel bike. Not on a gravel/touring bike loaded with gear, but on a gravel ride just made for its rider and a bottle of water. I think that would be a rather nippy ride. And no, I am not a 1x groupset person but I do think that with 12 gears you are incing darn close to not needing that front chain ring in most cases.

[@mh_dot_fm]

nice skids man!

[@Piplodocus]

This is a great move from Shimano. Kinda what I was saying about their 1x GRX options from the start: they should try match SRAMs wider range or use more MTB bits (which is why I run my 1x11 GRX with a SRAM 10-42t instead of the original Shimano 11-42t for more range). So, if you currently have 1x11 GRX on your bike, can you just change your RH lever and other 12-speed specific bits (and microspline), or will your levers then not match and you'll have to buy a new LH lever too else it'll look/feel weird? I already have a LH lever for the dropper/brakes. And I presume the old GRX in-line hydraulic sub-brake levers are still compatible? If you can do just a partial groupset upgrade at some point that makes the upgrade price more appealing. 🤓

[@matthewshultz8762]

Bold of you to assume any level of cross compatibility lol... I've heard that the brakes are the same from last gen.

[@Piplodocus]

@@matthewshultz8762 Yeah I presume the fact they describe the new levers as being designed for flared bars, but no previous mention on the 11 speed means I'd have to cough up an extra £250 (or whatever it is) for a new left hand dropper lever I don't really need, just to match a new right.

[@chrisridesbicycles]

Interesting that it‘s mechanical only. Shimano has either seen that electronic shifting is not a thing offroad or it comes together with an updated DI.2 XTR.

[@tonyg3091]

Electronic is not a thing off-road? 😂😂😂😂 SRAM AXS anyone?

[@jeskli11]

When I was buying my latest mountain bike (2nd hand), I originally wanted Sram AXS electronic shifting. In the end I found a good value bike equipped with Shimano XTR M9100 and honestly, the groupset is so well made and refined it really doesn't need to be electric. For riding on road, the shifter might feel a little too stiff as you are shifting a lot because of the jumps between the gears, but I can't notice any flaw off-road. I guess with the STI levers this only 'complaint' would be also eliminated. The Hyperglide+ is just that good if you have a high end lever (on the MTB side XT at least, SLX is way too clumsy and the feel is nowhere near as good).

[@chris1275cc]

Depends on what you want to keep and how big you want to go in the back. Other manufactures do HG compatible 12 speed 11-50,51,and 52 that means you could keep your wheels/hubs but loose the 10 tooth*, Left hand lever and (likely) both brake calipers will be fine if you can find just an OEM lever for sale. Chainset should be fine and the cranks look like the same BCD so at worst it would just be a new chainring. IF (and its a big fat IF) Shimano have used the same pull ratio you might be able to use your existing rear mech with a Wolftooth link or an aftermarket cage, might seem unlikely but they do have previous for this, Tiagra 4700 and GRX 400 rear mechs work fine with 11 speed 105 and above shifters (although you wont find it on any official compatibility charts). *If you really want the 10t (or even a 9!) don't forget Srams XD and XDR has been sub 11t for a while and you might be more likely to find an XD/XDR driver for your wheelset, defiantly worth looking into and weighing up the pros/cons before you go buying wheels or having new hubs laced.

For that specific setup, you would need wheels/hub with Microspline freehub support. Your existing road wheels most likely came with a HG freehub. But other than that, you shouldn't have any issues with converting a road bike to a 10-45 1x setup.

I have 11speed GRX 1x on my road bike (with a 11-46 garbaruk cassette and a garbaruk derailleur cage to make the it work with 11-46 (actually even 11-52 would be possible) work), the only problem is that the chainline is a bit wider and the Q-factor is also wider, I switched to a rotor road crankset and now the chainline and Q-factor are back to road standards. It's a nice setup, but if I would build a road bike again now, I'd probably go 2x Di2, sometimes I would like to have a bit smaller gaps between the gears, and the Di2 Shifters just looks so much nicer.

Can you mix the 10-51 cassette with the double 31/48 chainrings? When you mentioned the double setup, you listed 2 different cassettes, which suggests that they are the only compatible ones?

[@veganpotterthevegan]

I have serious doubts the derailleur could handle that. Your best option is probably a mountain crankset and the 2x friendly cassette. Or go 1x with a 36t chainring and something like the e*thirteen 9-50 cassette

[@simonstucki]

also you would have a lot of overlapping gears!

[@jonathanzappala]

A 31x51 is 4 mph at 83 rpm. I’d question why you want to go that slow. That’s get off and walk speed. If you wanted to go that slow why would you want a gear bigger than 50x11 to go along with it?

[@erlendsteren9466]

I think 12 speed with that 10 cog behind can increase descending 3% speed from 30 mph to 33 mph, allowing more power pedalling. Less descent it will not help me , because 11-40 is hard enough, more descent it will not help, because then I dont pedal anymore anyway. But I am tempted. It will convert the gravelbike to a combi- gravel-roadbike, putting the roadbike further away in my shed. The roadbike has several flaws. It cant go with fatter tyres than 26 mm, and the big cog on the cassette is only 25 teeth. And it doesnt have any suspension, and no dropperpost. Actually it is worse than gravelbike in sections of almost every journey, when the going gets rough.But it is a true pleasure going between 5% downhill and 5% uphill on good tarmac.

For a gravel bike mostly used on the road, I reckon the 10-51T with a 46T chainring looks interesting.

ok nice but nothing revolutionary, and I feel it would have made more sense to just go with micro spline for all 12 speed (also for road, so shimano should have ditched HG already back when they introduced 12 speed ultegra and dura ace). Why keep the HG body? What does it offer compared to the micro spline? (yes backwards compatibility for old wheelsets, but now if you want to go from 1x GRX to 2x, you need new wheels or at least a new freehub body if available) With micro spline you could still keep 11-xx cassettes but also offer (narrow) 10-xx cassettes and thus make life a bit easier for those who want a shimano road 1x setup (even though shimano doesn't offer a 1x chrankset, it's still something people want)

[@simonstucki]

Also I would really like some shorter cranks? 170, 172.5, 175, what is this nonsense? How about 155, 165, 175, would make a lot more sense.

No electronics???

Release dates please 🙏

[@jasonnorman6804]

It's available now, sigma sports have it in stock

[@serbanalexandru104]

I hope the prices of 2x11 and 1x11 grx will go down.

10-51, mmm just like MTB, I find it interesting groadies are using bikes which are essentialy using mtb tech ? Why not just get a mtb, then you can do real off road cyling.

[@erlendsteren9466]

I have a nice XC mtb bought used with slightly wrong stem and hilarious wide bar. Wonder if it would be nice to swop to dropbar and Grx brake/gearhandles? If it works it will be a fantastic gravelbike. I run it with 2.2 inch tyres now which maybe is the best graveltyres possible. Fast on smooth trails, fast on gravel, and fast on tarmac.

My SRAM XX1/force axs mullet setup is the same price. And lighter... 🤔

[@Csapi007]

Too little, too late! I've considered switching to 12 speed when I saw the GRX 12 speed at Unbound, back in the beginning of June (3 months ago). I've weighted my options and the track record of Shimano launches and went with a SRAM AXS equipped bike a couple of days later. Happy ever since. We've waited 3 months from the first sighting to the announcement. Considering Shimano's record, you could wait another 3 months for any of the components to be available to buy and you may get your 2024 bikes equipped with it in spring 2024. In contrast, when I've decided with SRAM AXS, I had the bike in two weeks time. Shimano always lacked on delivering what's announced!

[@FreedomOfSport]

Can already order it with delivery next day.

[@Csapi007]

@@FreedomOfSport Indeed. Unusual from Shimano.

[@cdeluise]

I want a Di2 version Shimano!

[@aux84]

Is shifter compatible (cable pull ratio) with shimano mtb x12 RDs? If not, it is a pure SCAM

[@MAGAIVER]

Ever since the 10 speed days road and mountain have had different cable pulls, I don't see why it'd be different now.
