When buying a new bike, there are a lot of choices to make, one of which is choosing what kind of groupset you want. If you want to do a mix of road and gravel riding, should you pick a road or gravel groupset? To help you out, Si rides Shimano’s GRX and Ultegra groupsets to see how they stack up against each other.

I decided to move(sell) from my old Canyon Ultimate CF 8 Di2 (rim brake version) to Canyon Grizl CF 8 GRX810 Mechanical, and buy 2 sets of wheels (1 - robust aluminum with thick tyres for Gravel and Bikepacking, 2nd - carbon light wheels with slick tyres for weekend road rides with friends). I think a gravel bike is really a "do it all" bike.

Did the same wuth the new endurace, gravel tires on the stock wheels, and 2nd pair of fancier wheels with narrower cassette and with the stock road tires. Got it with sram rival though which also has a clutch and doesn't give me any compromise on faster group rides on road ;) You have a small compromise on road, as much as i have small compromise on tough off road, but both are awesome :D

@runrideski6003 2 года назад

We bought Ultegra-equipped gravel bikes in the pre-GRX era. They came with the 46-36 (cyclocross) chainsets, 11-34 cassettes and the Ultegra rear mech DID have a clutch at that time. This setup has worked mint for us. I do go into the drops a lot for braking on steep downhills, so I'd really like to see how the braking from the hoods on the GRX levers compares.... that's the main upside I see to GRX.

@ad9898 2 года назад

I've put a GRX chainset and front derailleur on my wife's road bike mixed with 105 shifters and rear derailleur and it works fine. Giving proper low gears for climbing in the Alps.

@khaledzaidan 2 года назад

I run a mix of the two... Road chainset and front-mech (for the higher speeds range) with GRX cassette and rear mech (for the wider range and lower gears when climbing + the clutch mechanism)... and road shifters just because they were cheaper :)

@meister-t 2 года назад

Some things are just to create unnecessary incompatibility, like 2.5mm out on the front. limit screws can do that without requiring a new derailleur. The reason you do want a different rear derailleur, is because the progression is steeper as it moves from one sprocket to another. The angle is like that of a mountainbike derailleur, to accommodate the larger sprockets. But of course, they make sure you can't use a mountainbike derailleur with your road groupset, to force you to buy an entire groupset, if you want wider range on the back. There was a time, with certain groupsets, when rear derailleurs were interchangeable between road and mountainbike (same cable-pull ratio), but they quickly did away with that, when people started mixing in order to get a wider gear range. This is why there's a portion of the market that resists buying new stuff: because of all the BS where they intentionally make everything incompatible. You can't believe them anymore when they make up some reason/benefit to the change, because they've been doing that for too long (like a certain cable-pull ratio giving this or that supposed benefit, when they do the opposite years after, and when competitors aren't even in step with what direction to go). It's all just to make you spend money, again. Nothing is intended to last anymore. Not to mention how much it costs to replace a cracked rear derailleur.

@radzieckigraczproductions3 Год назад

This is why i didnt advance further than 9 speed, i can mix and match as much as i want with 9 speed shifters

@gratstagram Год назад

You hit it right on the head. Have you compared a GRX and Shimano mechanical road group? There are almost no differences aside from chainring sizes. It's literally a rebranding and some rubber coating on the brake levers. Boom. NEW GRAVEL GROUP. 🙄

@s.m.dickerson6712 2 года назад

Nice video... style and substance. I've run the previous generation Ultegra Di2 on my gravel bike for the last few years... has the clutch on the rear derailleur. I keep 11-34 on both gravel 650b and road 700c wheels, but do a seasonal swap of chain and chainrings - 50/34 for ~mostly road~ in the summer/fall, then 46/30 for winter/spring gravel.

@tomtiehatten8792 2 года назад

Nice presentation by Simon. I ride my Rose Backroad gravel bike as a recreational bike, not riding races. It works very well with a 1X set up, I'm only missing the very large gears when riding downhill but where I live there aren't any mountains so a biggest gear of 42x11 is more than sufficient (it's equal to a 50x13 gear). For riding on the road I use road wheels with 28 mm road tyres and I'm not slower/faster than on my previous road bike. For riding offroad I can choose 700c wheels with 40 mm tyres or 650B wheels with 47 mm tyres and these three wheelsets cover all of my bike activities. I think for someone who doesn't ride bike races a gravel bike is the all in one bike that many riders were looking for.

Really good for fast gravel; less so perhaps for knarly single track - but I have an MTB for that. A couple mates have a later Checkpoint with GRX and they are very happy, and other friends with later Checkpoint with SRAM gearing. They seem happy too….

@joefinlayson7738 Год назад

I recently purchased a 2022 Dura Ace Di2 groupset build with a new 2022 Cervelo Aspero 5. My plan has been to use the bike as both a road and gravel bike, as eloquently mentioned in this video, with two separate wheelsets. I started out by pairing 28mm road tires on ZIPP 303 Firecrest wheels, and it all seemed like a little slice of heaven. However, as soon as I changed to a gravel set up with ZIPP 303 Firecrest wheels running 40mm Pirelli Cinturato Gravel H tires, I learned that there is not enough space between the front derailleur pod, which attaches to the seat post, and the tire. My little slice of heaven quickly felt more like a kick in the nether region. After further investigation and MANY emails with Cervelo, I learned that they simply hadn't tested the 2022 Dura Ace Di2 12-speed groupset with this frame in order to provide guidance to local bike shops and customers. I was disappointingly told that Cervelo would do nothing to assist me as they apparently feel that making a disclaimer statement that "Cervelo does not guarantee compatibility with all groupsets" should suffice. (side note: I was very disappointed with Cervelo's customer service, as they simply told me I should've known better than to pair this groupset with this frame -- despite publishing very little information/guidance in the market). I am now left with the need to purchase another groupset (GRX 815 Di2) in order to use this rather expensive frame. So, in keeping with the question posed in here: what groupset do you use? My response is; I really love the Dura Ace Di2 12-speed -- its butter-smooth, nearly silent shifting is, like I already said, a little slice of heaven. Once I have a chance to ride the soon-to-arrive GRX 815 Di2 I will weigh in again with comparative comments. Until then, my $5k Aspero frame will need to wait to actually taste any gravel...

@swish6143 Год назад

How is the experience now with the 815? I am looking for a bike, and a 33/50t would be a nice option also on gravel or at least a 10-36 cassette. SRAM has that, but just with a 30/43t, so no gain since both ratios are almost the same.

I have Grx600 chainset on my Tiagra road bike, swapped straight on and lowered the front shifter a couple of mm. With an 11-32casette it is brilliant where I live in the Peaks where 20% climbs are 2a penny. You do have to spin 140rpm to get 70km/h though. I hardly ever miss the 50/34 chainset I took off. My gravel bike has a lowest ratio of 40/42 on 1x GRX, not quite low enough sometimes, and 40/11is frequently not high enough on the road. I will be fitting 2x to that when the chain ring is knackered

@marcusathome 2 года назад

Back in the day you could easily combine MTB with road groupsets, at least for 7, 8 and 9 speed. So you could combine the ST-6500 shifters with XT derailleurs and you had your perfect gravel setup. More compatibility means more freedom to chose, to mix and match. I'm still happy with this setup, great gear range, and easy to maintain.

Well these days they're no longer called "cyclocross", "adventure", or "monstercross" bikes; it's various levels of "gravel bike", that new invention that we never saw before, the one that needs to bring road levers to offroad bikes. Oh, thank you Shimano for delivering us the GRX, we never knew we needed it until you ended the compatibility between the road levers and MTB derailleurs, and also for being the godfather of our newly baptized bikes!

@swe223 2 года назад

A few years ago yes, but nowadays honestly there is no need anymore for MTB compatibility. You can use a 46-30 crankset, any road or GRX shifters with an Ultegra/GRX rear derailleur that can accommodate a 11-36 cassette natively, and even an 11-40 with something like a Roadlink. Honestly that's not bad, not expensive and very easy to find everywhere with good deals.

@alexshobbies2187 2 года назад

I have a road race bike with Ultegra R8020 and a gravel bike with GRX810 and they are remarkably similar. The big advantages I've noticed of GRX over Ultegra are that the rear mech clutch is a life saver on and off road (rough roads where I live) and the ergonomics of the the GRX shifters does not compare to the Ultegra shifters! The GRX hoods are the most comfortable place I have ever rested my hands on a bike! With the weights and looks being so similar I would say the only thing that I miss with GRX (I usually do mixed surface rides) is that I run out of gears on the top end very quickly. I have the largest ratio they offer at 48/31 and a 52/36 on my race bike. I think if I could have the perfect groupset I would start with Ultegra and swap in a cluthced rear mech and those amazing grx shifters!

I'm running my Foil di2 with an ultegra rx and 1x setup I use it for road duties and somewhat bizarrely bike camping too as I have an extrawheel trailer for glamping with the speakers and a lightweight bivvy setup for when I fancy waking up somewhere random but nice. Really easy to play with ratios plus running it 1x has more than doubled the di2 battery life.

Thanks for this cool video. I have a 2019 Fuji Jari 1.5 gravel bike with a Tiagra 2x groupset. Recently I've upgraded my rear mech with a GRX400 and a bigger cassette - 11-36 (prior to 11-34). Needed some time for fine tuning, but now it's working like a charm. At the end of the season I'll replace the front chain ring and the front mech with either ultegra or grx parts, depending what will be available.

I’m glad Si mentioned the looks as a factor - for me, I was trying to choose between the aesthetics of Ultegra (with RX RD) and the wider ratios of GRX. Didn’t want to choose “either, or” (I like to have my cake AND eat it), so eventually went with SRAM Force AXS Wide which has the looks that I like, with the wider ratios and available cranklengths too. It’s a great do-it-all solution. Pretty happy…except I do still lust after GRX 815 shifters - I think they’re the best looking component out there!

@ALeagueMan 2 года назад

My first "real" bike I bought last year has a 2x GRX. It was available within a week, and all road bikes had a 6+ month wait. Now I've never ridden a classic road 105 or Ultegra, however I'm not convinced I'm missing out on anything. I've put 32mm slicks on my bike in place of the gravel tyres, and just change them out when I plan to go out on the trails. Otherwise it basically lives on the road and I love it. One of the best purchases I've ever made. And for what it's worth I agree the GRX looks more rugged and less race like than Ultegra...but does that really matter to 99.99% of cyclists? Don't be put off buying a bike with GRX, you won't be disappointed...

@Fear.of.the.Dark. 2 года назад

Depends. You might be spinning a lot on road due to the grx speed combinations vs 105/ultegra. I have the 12-25 ultegra cassette which gives me single step combos for most road speeds as well.

@ALeagueMan 2 года назад

@@Fear.of.the.Dark. quite possible in some circumstances, but I'm not a competitive rider nor seeking to climb Strava leaderboards so I find it just fine. When it comes time to change my cassette I may look in to changing from 11-34 to 11-30. But these are minor gripes. I think if you're worried about spinning out on the road then you're probably not even considering a bike with a GRX groupset, and instead have a dedicated road bike.

@Fear.of.the.Dark. 2 года назад

@@ALeagueMan yes I do have one road bike only since I ride on tarmac most.That is point I am making since you said 99% of the cyclists will do fine with GRX. If you are really doing gravels majority of the times then it is ok to get gravel bike with gravel groupsets. If you get gravel bike with gravel groupset and you are doing road tarmac 95% of the time, then you will feel the miss of 105/ultegra gear combinations. Some people keep interchanging both road and gravel bikes and decide to buy one but they are not really built for same stuff. Very important to pick the right tool for the type of terrain you will ride in most.

@bitgeist21 2 года назад

I'm a generation behind the latest Ultegra 8100 Di2 group set, but what I do have (on my C-Dale Synapse) is an Ultegra Di2 Rx rear mech. So, it's a road mech WITH the built-in clutch for better chain control on "less than pristine" tarmac. In terms of GRX on the road; no me. Shimano designed these group sets for specific purposes and I, for one, like the right tool for the right job. If I'm building a Topstone Carbon for gravel riding; GRX. If I'm building a SuperSix to tackle the Alps or the Dolomites; Ultegra Di2. (Of course, your frame set of choice will do just as nicely as well :-)

I have an Ultegra RX rear derailleur on my Scott Addict gravel/road bike and it has a clutch. Additionally, I have fitted it with an 11/40 from my mountain bike with a derailleur adapter and it worked great for a very difficult gravel ride. I use a standard 11/30 for road riding. As long as you can do some simple mechanical work, you can mix and match pretty well. I find the 50/34 front will spin out at about 30mph on the road down gentle grades so I can’t imagine using a 48/31 GRX.

@johanreberg4872 2 года назад

When I bought a new bike coming in to this season I choosed to go for a gravel bike since I knew I was gonna go riding alot on the gravel roads close to where I live. The 2x11 gearing with 46/30 and 11-34 casette suits me both for gravel and tarmac. A setup with say 50/34 would not make ride faster since I hardly can use the heavier gears on the setup I got now. The power is not there. 😁

@marcvalade94 2 месяца назад

Over the years I have had more issues commuting with my hind derailleur catching in the spokes then I had flats. And carrying my patch kit and extra tubes was of no use when that append! To remedy this I am upgrading to GRX 10 speeds at the back with large gear clutter to minimize the risk of needing to go on lower gear and put distance between the wheel and the derailleur. I believe also that GRX will prevent much of the side motion towards the spokes being more sturdy and keeping the chain from swinging. An 11 or 12 speeds would keep me closer to the spokes it seems. Performance wise, I do only 40 km a days in two stretches so I don't really get to experience the need to time my cadence and breathing to perform against those who do! My ride is also very changing and not of long continuous stretches. I am lucky to pass 2 lights without a stop at time! I still do my road ride on a 54 teeth front chainring on the 12 and 11 teeth sprocket. I actually want to eventually go on a 55 teeth chainring. Reason is to even my wear on the cassette gears and get more torch downhill. For my gravel part of the ride, I will go down on the smaller chainring to keep the derailleur away from the spokes. Due to my use of unconventionally large chainring, I need to sacrifice some of the low gear at the back when I am on the 54 teeth. Over the last few years I found that I now do the full paved portion of my ride on the big chainring and rarely need the 2 larger sprockets at the back (34 teeth). I resume to them in snow when I am packing a bunch or in heavy winds. So my need to use the 42 teeth sprocket will probably never be necessary while on the large chainring anyway. I also lose some capability to get a much smaller small chainring. That means I am not as capable to climb bumpy gravel hills then a more mountain biker would be. I need to start hiking earlier! But that is fine with me. On the trail I then use my small chainring like a one-by 40 teeth chain ring over the full cassette. Over the next few months I will see if it is worth switching the front derailleur to GRX as well to allow reducing the small chainring teeth count. So my commuting bike is evolving versatile, and while it does you grow biking solitarily. In these lonely times, you have no care of being faster on the road or in the mountains since you are competing solely with yourself! But I have to admit that I enjoy racing e-bikes on the bike lane!

My Trek Checkpoint has the GRX on it and I daily commute with this bike and occasionally ride gravel. This is a great drivetrain for gravel and bike adventures but if you are out riding road, you're gonna max the bike out. The fastest I've had the Checkpoint up to is 36.8 mph, it was a very nice downhill with tailwind. If I'm in the flats and no headwind, I can maintain about 25-27 mph. So it does me good for commuting not so much in road races.

The range is 11-50 and my only complaint is cassette weight - it continues to rotate a bit when I stop peddling giving an unsettling feedback bump. I've ridden the ZRace for years on my mountain bikes and it has remained reliable and clean shifting. My upgrade will be a lighter cassette and maybe go 10-50 using an xD freehub to get more top end on the road.

I’ve put full grx 810 on it, 42-11/40. it’s flawless. I’ve got the same cassette on my road wheels as the chain will feel too long if I put a say 11-36 105 cassette on. I know as I have this cassette fitted to a turbo training wheel and it gets a bit noisy in the bigger cogs. the only thing I can fault is the slightly bigger jumps n cadence when I go for fast road only rides with the 11-40

I have two gravel bikes, Nina and Un are their names; both run Ultegra 50/34 crankset and XT 11-42 cassette and both are 11 speed 8000 series with hydraulic brakes and mechanical shifting. Nina is set up with a flat bar using XT derailleurs, shifters and brakes. Un has a drop bar using Ultegra shifters and brakes with an Ultegra front derailleur and an XT rear derailleur, he has a tanpan mechanism to change the Ultegra road pull ratio to the ratio required for the XT mountain derailleur. Both bikes function excellently but I would like it if I could get the same gearing with electronic shifting.

It may be worth knowing that you can combine 1x11 GRX rear mech with it 2x11 front mech without issues, allowing you to combine the 11x42 cassette with your 2x crankset of choice. Came across it on a few Velotraum bikes at work, works just fine.

@tomtiehatten8792 2 года назад

What also works if you use a 1x11 set up is a 11-46 cassette, although Shimano says something else. It's even possible to use a 51 cog if you replace the rear derailleur cage for a one from Garbaruk so if you want to use mountainbike gears with Shimano GRX there are some possibilities. The other possible thing is to use SRAM parts where you can mix road and mountainbike parts without any trouble.

@tongucyaman Год назад

This was the information that I was looking for. Can you clarify a bit more? I plan to use the GRX di2 RX800 in a 2x setup with a 48/31 Crankset and 11x42 Cassette. Simon, in this video, specifically mentioned that 11x42 is for a 1x setup. I hope that you are right.

@hzunasdfgbciw 2 года назад

The new Ultegra / Dura Ace shifts faster than the GRX, but old shifting speed is excellent, too. Ultegra doesn't need a cable connection to the shifters and adds the option for additional shifting buttons - good for TT, but not relevant for gravel. I don't own a gravel bike so far, but on my MTB 48:11 falls a bit short. So I'd like to have the option for 52:11 for rougher roads on a gravel bike.

For me: GRX 1x with a 38T absoluteBlack oval chainring and a SRAM XD driver freehub with SRAM 10-42 cassette for my gravel bike. I seem to be able to get up everything and not spin out too much on the road, for everything from fun-time random MTB-level trail stuff to bikepacking. I have no idea why Shimano use microspline on MTB so you get a little 10t for wider range (as well as bigger low end gears), but for gravel 1x they don't come with microspline, just standard shimano spline, so you just don't get the same range as SRAM 1x and I like that little bit of extra top end. 420% vs 380% gear range does make a difference. That's 96 vs 105.6 gear inches for the geeks amongst you, with the same 25 gear inches in the bottom end (and I reckon that oval helps a tiny bit getting those extra few crank rotations and stopping me "stalling" when I'm at the limit of a rough steep climb)! I've dropped the chain a few times when the clutch has accidentally been off and sometimes ridden through so much thick mud in the winter it's still forced the chain off the chainring, so as a MTB-er too, GRX 1x defo seems the one I'm most confident with for the riding that bike does. I'm going to pick up my new 105 road groupset I ordered tomorrow for the road bike. I would have been somewhat tempted to go 2x GRX on that, but there's unsurprisingly no GRX rim-brake option (and I don't think it "needs" a gravel groupset), so 105 is the sensible option, and variety is the spice of life anyway.

Larger tyres increases the circumference of your wheel and affects how far you move in a given gear ratio, so a 50-11 on 28mm tyres isn’t too dissimilar to a 48-11 on 42mm tyres.

@Philip_Hatchet 2 года назад

I feel you guys missed the most important aspect about these two groupsets. Is there a difference in the durability? People use their gravel bikes in the winter and worse weather, so is that a smart thing to do or does it not really make sense? There is no difference in the harm to the frame, there is no difference in price between an ultegra roadbike or grx gravel bike, so why do people still make this decision?

Because of the weight difference in the bikes I don’t find the easier gearing in grx makes much difference up hill but I used the gravel bike as a commuter with road tires for a while and definitely noticed the difference on the road. Really only because of the jumps in ratios on the flats and lack of bigger gears on descents. Having said that if I was comparing mechanical to mechanical I don’t think I’d care. The biggest difference in the bikes for me is the geometry.

We have both Ultegra R8020 and GRX400 hydraulic brake levers. Not sure if this applies to all but the GRX400 hydraulic levers feels way better than the Ultegra R8020 lever. The GRX have that ‘springy’ lever feel which makes braking much lighter on the hands.
