A few years ago we tested Shimano's 105 and Dura-Ace mechanical groupsets against each other, and learnt that they were pretty much, in terms of feel, exactly the same. But Shimano has since released new versions of both, and what's more they're both Di2 only! So is there any difference? Is Dura-Ace still virtually exactly the same as 105? Alex and Si conduct a series of tests to find out!

What do you think of Shimano 105 being Di2 only? Let us know your thoughts in the comments below!👇

@chones_ Год назад

Ok, I'll bite. What is Shimano 105 DI2? Pretty sure it's more rare than the Hooded Grebe

@ragwort3369 Год назад

Having used Di2 for a while now, it still strikes me as a solution looking for a problem, and doubly so at the riders 105 is aimed at. My experience is that Di2 does nothing that well set up mechanical shifting won't do, only at considerably more expense and without the "fixability" of mechanical systems. I'll be moving the bike on soon and going back to an exclusively mechanical fleet. EDIT: In fairness, I should say that mechanical shifting doesn't allow me to have "extra" shifters on top of the hoods, which I can see is a possible advantage (although I can shift mechanically from most hand positions anyway). Nor indeed can I control my Garmin using mechanical shifters, but given that it's on the handlebars anyway, that doesn't seem like a particularly useful feature!

@strawhorn1 Год назад

So from this and previous videos should we update the rankings. Tiagra mechanical groupset of the people and 105 di2 electronic groupset of the people. My next bike will be 105 di2. Got a close up view at a Ribble test day.

Three reasons I went Ultegra 8100 over 105 for my upcoming build. First, the hidden buttons are meaningful to me. Second, the brakes.

Another brilliant review! Glad noone wiped while blindfolded. I am really fortunate that I have a Trek Domane ProjectOne with Ultegra Di2 12 (2022) and I bypassed the DuraAce (a fantastic option, but at a substantial price jump) because the group weight and the performance differences would be imperceivable for me as an amateur athlete (and still in my first year back in about 35 years off of cycling). At the time of my purchase, the 105 group wasn't available in a Di2 12 cassette version. Any of the 3 top Shimano groups are so good, for most people it comes down to budget and preference than performance.

@trainiax Год назад

@@whatwelearned Well, if you limit "entry level" to bikes with named groupsets with STI levers above a certain price point, then of course the shifters are more expensive - but that somewhat misses my point. The point is that a mechanical shifting mechanism by itself is not expensive to produce - Acera or even Alivio flat-bar shifters (equivalent to Claris or Sora) are indeed not much more than $25. But that's the only potential cost savings for Di2 since it's the only component that's eliminated. STI levers are more expensive in part because they combine the braking mechanism - and that doesn't change with Di2. I also mentioned derailleurs - because up to now, Di2 derailleurs have been massively more expensive than mechanical: 3 to 4 times the price of their same-tier mechanical counterparts, and 10 to 20 times the cost of an entry-level derailleur. That huge price gap will never disappear as long as they have all the same mechanical bits with a motor and electronics added on top.

Am I right in thinking that swapping the cassette for an Ultegra cassette to get the Hyperglide+ would result in *almost* the same shifting feel as Dura Ace? A new CS-R8100 (Ultegra) cassette is £80-£90 in the UK at the moment, depending on the size. Swapping it appears to be one way of addressing one of the few real shifting differences, and would seem to be a sensible upgrade. Is that correct, or am I missing something?

@chrisridesbicycles Год назад

Having a sleeker front derailleur near the ankles might be a big plus for some. 🙃 I was riding 12s HG+ on the MTB for a few years before I got my road bike (11s Ultegra mechanical) and shifting to a harder gear immediately felt clunky. HG+ makes a difference.

Me too, and honestly, if you shop around and wait for sales and bargains, Ultegra can be had nearly as cheap as 105 - and when I was building up my last two bikes, Ultegra was still a HUGE jump up in performance over 105. That gap has closed somewhat though. Today, if I was building a new bike, I'd be taking a very serious look at 105 and weighing out the prices.

@Metal-Possum Год назад

Meanwhile I still have Campagnolo Veloce 10 speed. It's not perfect, but they made absolutely no effort to make it look or feel cheap, which is why I like it so much.

@lukewalker1051 Год назад

I rode Campy 10s for years. Btw, there was virtually nothing between Veloce and Record for Campy either. 10 speed is the sweet spot. If you want good, economical cable shifting and my preference, try Sram Rival 22 mechanical. I even prefer it to Campy mechanical and I rode Campy for decades. No electric shifting for me and I build all kind of bikes including high power ebikes.

@Metal-Possum Год назад

@@lukewalker1051 I'll never use SRAM except for 7/8 speed cassettes for random builds. I work as a bike mechanic and SRAM is by far the least enjoyable stuff to see coming into the shop apart from Shimano Tourney. I'm a big fan of inexpensive 8 speed drivetrains, Shimano Altus, Acera etc. They shift flawlessly, cost very little, and are much more forgiving. Yeah, the pivots might wear faster but the tolerances are so forgiving that it doesn't really matter.

@alexmichl3137 Год назад

Wait so in "tests" you basically can't tell a difference, but the conclusion is there is a difference? Plus you said at the start that you have identical bikes, but at the end you justify the overpriced dura-ace by saying that the bike overall is much better equipped? Like guys at least dont dismiss your own points when you try to sell these overpriced components and bikes.

@All4Grogg Год назад

Shimano and Sram are getting close to having their gigantic mountain of patents expire for their original electronic group sets. I wouldn't be terribly surprised if they continue down the hierarchy of product offerings, knowing that "generic" offerings are coming soon to compete. Most patents expire after 15 years, di2 was released 13ish years ago which likely means - if you include tooling/manufacturing lead times taking it from patent to test to manufacture to test then to produce- that the bigger broader patents are months away from expiring. Also, Sram's wireless shifting glove patent as well, apparently, thanks google.

@BM-xm1zz Год назад

Alright so I firstly, get job guys this is a very comprehensive comparison. That being said, one particular mention stood out to me. The feeling a light bike has as you push up a climb - bikes today weigh a sh*t ton in comparison to a few years ago. With most high end bikes weighing the same as 105 spec bikes from 2016, have we actually moved forward? Yes disc brakes help and improve confidence but gone is the sleek short cage derailleur instead of the one size fits all and the actual lightweight sub 16lb bikes that used to be attainable. People today pay 16000 for a 17lb long cage, wide ratio bike. It’s too bad we have to compromise straight blocks and lightweight builds to satisfy a need to continuously change standards

@RichardMigneron Год назад

Maybe a combo of all the 3 groupsets would be the perfect bike. For exemple, I ride long roads and don't use my brakes much, but I constantly shift in the rear and only when climbing hills in the front. So a combo of mainly Ultegra with a rear Dura-Ace derailleur and 105 brakes would be perfect, and an extra climbing shifter on the bars (105 can't do that). But my big pb with all these are the cassette options which don't suit me at all. Love my current 12-25 (got an 18 instead of the useless 11), which is perfect !

But you can narrow the gap significantly by upgrading to the 105di2 to the Ultegra front mech and casette (8170). Those upgrades would cost an extra £300 rather than an extra £1,600. Then the only thing you don’t have the is the servo wave technology and the extra di2 buttons.

@lukewalker1051 Год назад

Now an honest assessment. For twice the price there is nothing between these two groupsets. The weight diff is nebulous. So, why did Shimano do this? Because they could commonize tooling for the 105 with cheaper materials...same design language and architecture...and charge twice as much for DuraAce for poseurs that have to have the DA name and....upcharge the consumer for 105 for more profit over cable 105. Cable 105 is what it still should be at a lower price point. The cycling industry fleecing the consumer who succumbs to marketing. There is absolutely no reason for DA to even exist with Ultegra other than Shimano knows people will pay for the name. Marketing and profit. Last thing is, there is nothing between the performance of these bikes tested. You could perform the same experiment on any pro team...or rank amateurs. Biggest difference was the deepness of the wheels for aero difference and that didn't matter to change the balance of which rider won the sprint. In a short race, Alex can hold Si's wheel until the sprint and then Alex's bigger sprinting wattage wins the race on either bike. Si would likely beat Alex in a long race again on either bike. In all my years racing, the fastest guy always wins independent of which bike he brought the race. One of the fastest racers I ever knew raced 105 cable on an old De Rosa aluminum bike with box section wheels. PS. who really wants 12 speeds in back with narrower cog spacing and narrower chain? 10 speed was the sweet spot.

@mikew9743 Год назад

Mechanical 105 had a major flow in that if you were trying to shift into big ring middle of a hill its often not very effective. Otherwise it was a good groupset and more importantly a cheap groupset. Mechnical dura ace on the other hand was the best mechanical groupset ever made frankly and it was very light. Really diff between DI2 DURAACE and 105 is really about the weight which might seem small until you add up a entire build. Full dura ace builds can often be 2-3kg lighter than a 105 di2 build and that kinda of weight especially for a lower weight rider could be a fairly substantial advantage on the climb.

I've got Ultegra Di2 on my spare bike, race bike and TT bike and I think it offers the best value. Use a DA cassette and there's very little difference to a full DA set up that costs much more

@ericcoxtcu8037 Год назад

I love the conclusion - Ultegra is where I usually end up. We just ordered my son his first real race bike (he's in college), and made the decision to move from the 105 bike to the Ultegra for a bit more. Like Orbea, the move brought upgrades to the frame, wheels, and handlebar/ stem for not much more.

I remember my first bike had 105. And I was like man I wish I had Durace like my friend. And then I stopped riding and sold bike. That was 10 years ago in college. Now I have a gravel from Cannondale with Adventx and to be honest it’s all same thing for me. I’m not that advanced to care. If I learned one thing, just ride and have fun. If I lose 40 pounds by riding bike I’ll be way faster than upgrading to Durace.

Great point! The top end parts are really nice, but enjoying the ride is the most important thing 🙌

I think Ultegra Di2 11 Speed with 105 Crankset and Cassette. Is still the way to go if you want Di2.

@lamaralvarez7385 Год назад

The long cage of shimano 105 is more versatile with more group sets.The shimano 105 long cage is more robust and can even wrap around a mountain range 11 42 cassette, something that the short cage of Dura Ace is incapable of,which gives 105 the upper hand.

What 11-42 12 speed cassette have you tried?

@thevintagehifiambassador8524 7 дней назад

so, if the answer would have been: "Nope, Dura ace not better than 105, not one slight bit" , what would the industry have thought about such a statement especially Shimano and the their dealers ... is there any price difference from 105 to Dura Ace? Don't know as I have not cycled for 25 years now :-)

@thereisnoiindaly Год назад

So, is there a single 105 component that can be switched out that would close the gap and make it more difficult to tell the difference? Can the electronic groupsets even mix and match the same way that the mechanical ones can? Obviously, GCN could put the exact same wheel or crankset on both bikes. How about other components? That would seem closer to the type of setup someone who builds a bike up rather than just buys it outright would have.

@JDMthwmn 9 месяцев назад

Use the Ultegra 8170 front mech and cassette. You’d then have a claimed 45% faster shifting.

@vustatube Год назад

I'm curious to know, I'm running ultegra 12sp groupset, can I use the 105 12 sp cassette? Only because of cost difference.

@Wazi1989 4 месяца назад

yes you can, but max to 34s on back

@janwillemkuilenburg7561 Год назад

105 di2 is faaaaar too expensive. NO chance that I will ever spend that cash on that groupset. It would mean a shift to a more reasonably priced brand.

@DG-tf9rp Год назад

If both bikes would have the same cassette (ultegra ultra glide+) chain, and good bottom Bracket, after a shift. what would be the difference? they should both Di2 shift the same. . And pedal the same. Stick with 105?

@edoaditya8982 Год назад

Even with all of the videos from gcn and other youtube channel , i still cant see the justification that i need before switching to electronic groupset.

@JIMMYHIBBS1 Год назад

105 with a Dura-Ace cassette is all you need then ?! …. When I was a kid (and fast) I had Dura-ace …. The first gen STI levers - OMG - coming from 105 down tube shifters at the time - I could tell the difference 😂

@glyndonwakeman7420 Год назад

Exactly what I was thinking. Swap out a cassette for D/A and the weight diff decreases and so does the diff in shift quality, and some of your hard earned $. But the fact they had to listen to the sound of a FD motor says they couldn't tell the difference blindfolded.

@gcn Год назад

Could you go back to Down tube shifters 🤔

@@gcn well - at the time I was doing mostly 10 and 25 mile time trials with Tri-bars on my road bike - so actually down tube shifters were pretty good

@philthewriter Год назад

Don't see how ramps on the cassette would make any difference at all to the feel or speed of shifting into harder gears - the chain only touches the sides of the cogs when shifting into easier larger gears? Know it's a paid promotion, but sounding incredibly all-out advert with the promotion of "Hyperglide Plus".

I’m assuming you can run a DA cassette with 105Di2 but would be more restricted with gear range?

@GilbertTang Год назад

For the stationary tests with someone else shifting, I would have really liked you adding an unidentified third control groupset, perhaps even from another brand (which is admittedly hard when Shimano is paying for the piece). Plus, not just blind but also put some ANC headphones on with music playing to mask the shifting sound.

@gcn Год назад

Masking the shifting sound is a great idea, next time 🙌
