Dura Ace 7800 Vs 105| In Detailed Comparisons
I have to be honest, when I was first introduced to the Dura Ace 7800 group set, I thought there was no way I could afford it. My 105 group set had been serving me well for a few years and I didn’t see any need to upgrade. But then I started doing some research on the differences between the two and discovered that the extra cost might be worth it. In this blog post, I’ll compare the two group sets in detail, letting you decide for yourself which is best for you. Spoiler alert: Dura-Ace is pretty amazing. But let’s not get ahead of ourselves…read on to find out more!
Dura Ace 7800 Vs 105
There are key differences between the Dura-Ace 7800 and 105 groupsets. The Dura-Ace is Shimano’s top-of-the-line offering, while the 105 is their entry-level groupset. The most obvious difference is in the materials used; the Dura Ace uses higher quality alloys and carbon fiber, while the 105 group uses lower quality alloys and plastic.
This results in a weight difference of about 200g for a complete groupset. Another key difference is the shifters; Dura-Ace shifters use titanium internals for smoother shifting, while 105 uses steel internals. Finally, Dura-Ace brakes use ceramic pads for better performance and durability, while 105 uses rubber pads.
These differences result in a significantly higher price tag for the Dura-Ace group.
When it comes to choosing a groupset for your road bike, you have a lot of options these days. But if you’re looking at Shimano, two of the most popular choices are Dura Ace 7800 and 105. So which one is right for you?
Here’s a quick overview of the main differences between these two groupsets:
Dura Ace 7800 is Shimano’s top-of-the-line offering. As such, it features all the latest technology and materials. It’s also significantly lighter than 105.
However, all that performance comes at a price
– Dura Ace 7800 is quite a bit more expensive than the 105. 105 is Shimano’s more budget-friendly option, but don’t let that fool you
– it’s still a high-quality groupset that can perform exceptionally well. It doesn’t have all the bells and whistles of the Dura-Ace 7800, but it’s still an excellent choice for many riders.
And because it’s less expensive, 105 may be the better option if you’re on a tight budget. So which one should you choose? Ultimately, it depends on your needs and preferences.
If weight is important to you or wants the latest Shimano technology, then Dura Ace 7800 is worth considering. But if cost is a factor or you don’t need all the extra features offered by Dura Ace 7800, then 105 could be the better choice.

Which is Better, Shimano 105 Or Dura-Ace?
There is no definitive answer to this question as it depends on personal preferences and what you are looking for in a bike. However, we will compare the two groupsets so you can make an informed decision. The Shimano 105 is considered to be the more affordable option between the two, while still providing great quality.
It is an excellent choice for those looking to get into road cycling without spending much money. The Dura-Ace is Shimano’s top-of-the-line offering and is used by many professional cyclists. It is very lightweight and provides smooth shifting.
It is also more expensive than the 105. So, which one should you choose? It depends on your budget and what you are looking for in a bike.
If you are just starting, the 105 would be a great option. However, if you are an experienced rider or are looking for a high-performance bike, then the Dura-Ace would be a better choice.
What Year is Dura-Ace 7800?
Dura-Ace 7800 is a Shimano groupset that was released in 2005. It was the first Dura-Ace groupset to use 10-speed cassettes and chains and featured an updated crankset design. The 7800 series was Shimano’s top-of-the-line groupset until it was replaced by the 7900 series in 2009.
Is Dura-Ace Compatible With 105?
There is a lot of confusion out there about whether Dura-Ace and 105 components are compatible. The answer is yes, they are compatible. Here’s a breakdown of how the two groupsets compare:
Dura-Ace is Shimano’s top-of-the-line road group, while 105 is their entry-level offering. As you would expect, Dura-Ace offers better performance and durability than 105. It’s also significantly more expensive.
One area where the two groupsets differ is in their shifters. Dura-Ace uses Shimano’s STI (Shimano Total Integration) system, which places the brake lever and shift lever together in one unit. 105 uses a separate brake lever and shift lever (known as Dual Control), which some riders prefer.
Another area of difference is in the crankset. Dura-Ace offers both standard and compact chainrings (50/34 or 52/36), while 105 is only available in Standard (53/39). This gives you more flexibility when it comes to gear ratios with Dura-Ace.
Finally, Dura-Ace wheels tend to be lighter and of higher quality than those with 105 groupsets. However, both groupsets will provide you with reliable performance and durability if properly maintained.
How Many Speeds is Dura-Ace 7800?
Dura-Ace 7800 is a 10-speed groupset.

Shimano 105 R7000 Vs 5800
There’s a lot to love about Shimano’s 105 R7000 groupset. It offers much of the same great performance and features as the top-end Ultegra R8000 but at a more affordable price point. For many riders, 105 is the perfect balance of quality and value.
But what about when you compare it to Shimano’s previous generation 105 groupset? Is the newer R7000 worth the upgrade? Let’s take a look at how these two groupsets stack up against each other.
Regarding shifting performance, both the R7000 and 5800 are excellent. Shifting is crisp and precise with either groupset, so it really comes down to personal preference here. The big difference is in the hood design.
The R7000 has been updated with Shimano’s new asymmetrical hood design, which many riders find more comfortable to hold onto. The biggest update for the R7000 is definitely a wider range of cassette options. You now have 11-30t and 11-34t cassettes available, giving you much more gear choices for climbing or riding on hilly terrain.
This was a welcome addition for many riders who felt limited by the older 5800 cassette options. Another nice update for the R7000 is that it now includes disc brake compatibility out of the box. With the 5800, you had to purchase a separate disc brake kit if you wanted to use them (although some bikes came stock with disc brakes).
Now, all you need is an adapter kit (sold separately) and you’re good to go with hydraulic or mechanical disc brakes. This makes it easier than ever before to upgrade your bike to discs if desired. So, which one should you choose?
If you’re considering upgrading from an older 105 groupset or even lower-end Shimano components, then going with the R7000 is definitely worth considering. The updated hood design, a wider range of cassettes, and disc brake compatibility make it a great option for today’s rider.
Dura-Ace Groupset
When it comes to high-end road bike groupsets, there’s really only one option that stands out above the rest: Shimano Dura-Ace. This Japanese company has been making bicycle components for over 90 years, and their top-of-the-line Dura-Ace groupset is the result of all that experience and expertise. So what exactly is a groupset?
It’s simply a collection of all the parts needed to build a complete road bike, including the frame, fork, wheelset, drivetrain (crankset, chain, cassette, derailleurs), brakes, and handlebar/stem/Seatpost. And Shimano offers three different versions of their Dura-Ace groupset: mechanical (shift levers connect to cables that operate the derailleurs), electronic (shifters send wireless signals to motors located in the derailleurs), and hydraulic disc brake (shifters and brakes both use hydraulic fluid for ultimate stopping power). No matter which version you choose, you’re getting some of the best components money can buy.
The crankset is incredibly stiff and lightweight thanks to its hollowed-out design, while the shifters are sleek and ergonomic. The chain is also very strong and quiet thanks to special coatings applied to both the inner and outer plates. And perhaps most importantly, each component works seamlessly with all the others to provide an amazing shifting performance that will make even the most experienced cyclists drool with envy.
If you’re looking to build up a new road bike or upgrade your existing ride with some quality components, look no further than Shimano’s Dura-Ace groupset. It’s simply unmatched in terms of performance and reliability.
Ultegra 6800 Vs 105 R7000 Weight
When choosing between the Ultegra 6800 and 105 R7000 groupsets, one of the key considerations is weight. So, which is lighter – Ultegra 6800 or 105 R7000? The answer may surprise you… both groupsets weigh in at around 2,200g.
That’s right – there isn’t a significant difference in weight between these two popular groupsets from Shimano. So, if weight isn’t a deciding factor for you, what else should you consider? Well, Ultegra 6800 does offer some slightly nicer features than the 105 R7000.
For instance, it has better shifters, brakes, and slightly lighter crankset options. However, these benefits come at a higher price tag. Ultimately, the decision between Ultegra 6800 and 105 R7000 comes down to your budget and personal preferences.
If you’re looking for the best possible performance and aren’t worried about spending a bit extra, then Ultegra 6800 is probably the better option for you. But if you’re on a tighter budget or prefer simplicity over bells and whistles, then 105 R7000 could be the way to go.
105 Groupset
If you’re shopping for a new groupset for your road bike, the Shimano 105 groupset is an excellent option. It’s affordable yet still provides high-quality performance. Here’s everything you need to know about the Shimano 105 groupset.
The Shimano 105 groupset is designed for entry-level to mid-level road cyclists. It offers many of the same features as the higher-end Shimano Dura-Ace and Ultegra groupsets but at a more affordable price. The 105 groupset includes shifters, derailleurs, crankset, bottom bracket, chain, and cassette.
Shifting is smooth and precise with the 105 shifters. They have a slightly longer lever than the Dura-Ace shifters, which makes them easier to reach when you’re in the drop position. The front derailleur has a wide gear range that’s compatible with double or triple cranksets.
And the rear derailleur has a Shadow design that helps protect it from impacts and crashes. The 105 crankset is available in both compact and standard sizes. It has hollow forged arms that make it lightweight yet strong.
The bottom bracket is included with the crankset and is available in either English or Italian threading. The 105 chain is compatible with all Shimano 9-, 10-, and 11-speed drivetrains. It has been treated with SIL-TEC coating for smoother shifting and increased durability.
The cassette comes in several different gear ratios depending on your riding style and terrain preferences.
Dura-Ace 9000
There is perhaps no name more revered than Shimano Dura-Ace when it comes to high-end road bike groupsets. The Japanese component manufacturer has been producing top-of-the-line groupsets for decades, and the latest generation – Dura-Ace 9000 – is widely considered the best Shimano has ever made. Here’s a closer look at what makes Dura-Ace 9000 so special.
First introduced in 2013, Dura-Ace 9000 was a ground-up redesign of Shimano’s flagship groupset. Every group aspect was rethought and improved, resulting in a lighter, stiffer, and more efficient system. One of the most notable changes was the switch from traditional square taper bottom bracket spindles to larger diameter hollow axles.
This saved weight and increased rigidity, improving power transfer from the pedals to the drivetrain. Another big change with Dura-Ace 9000 was the adoption of direct-mount brakes for both the front and rear calipers. This resulted in a significant reduction in weight as well as an improvement in braking performance thanks to increased stiffness.
And while some riders initially expressed concern about losing the quick-release lever found on older designs, Shimano addressed this by including an adapter that allows standard QR levers to be used with Dura-Ace direct-mount brakes. The shifters were also completely redesigned for Dura-Ace 9000, ditching their bulky integrated brake/shift levers (ISBL) for sleeker separate units that are more ergonomic and comfortable to use. Other notable changes include shorter chainstays compatible with wider tires (up to 28c), revised gear ratios that better reflect modern riding styles, and an optional power meter compatibility kit.
All told, these updates make Dura Ace 9000 one of the most impressive groupsets on the market today – and it’s no wonder that it’s become a favorite among pro cyclists and serious amateurs alike. If you’re looking for top performance from your road bike, there’s simply no substitute for Shimano’s flagship offering!
Dura-Ace Groupset Price
The Dura-Ace groupset from Shimano is one of the most popular and sought-after options for high-end road bikes. It’s known for being lightweight, durable, and fast, making it a favorite among competitive cyclists. But all of that performance comes at a price tag that’s not cheap.
So, how much does the Dura-Ace groupset cost? The short answer is that the Dura-Ace groupset will set you back anywhere from $2,000 to $3,000. That might seem like a lot of money, but when you consider all of the features and benefits that come with this top-of-the-line option, it’s actually quite reasonable.
Here’s a closer look at what you can expect to pay for each component in the Dura-Ace groupset: Shifters: $300 – $400 Derailleurs: $250 – $350
Brakes: $200 – $300 Crankset: $600 – $700 Cassette: $200 -$300 chain:$100-$110
As you can see, the biggest expense in the Dura-Ace groupset is the crankset. This is because it’s made out of carbon fiber, making it both lightweight and strong. The shifters and derailleurs are also quite expensive because they’re integral to the smooth shifting that Dura-Ace is known for.
The brakes are also fairly pricey because they provide maximum stopping power without adding extra weight to your bike. And finally, the cassette and chain are less expensive than some other components but still essential parts of the overall groupset.
Shimano Dura-Ace
Shimano Dura-Ace is the top of the line regarding Shimano’s road bike groupsets. Its race-bred technology trickle down from their pro teams that have won some of the biggest races in the world, like the Tour de France. Every component in a Dura-Ace groupset is designed for one purpose: to perform at its best.
From the crankset and bottom bracket to the shifters and derailleurs, everything about Dura-Ace is built for speed and efficiency. The chain has been specially designed to work with Dura-Ace components for smooth, precise shifting. One of the most impressive things about Dura-Ace is how Shimano has made such high-performing components while still maintaining them relatively lightweight.
The crankset, for example, weighs just 665 grams (including BB). And despite all of its features and technologies, the entire group set only weighs 2,265 grams. That’s impressive, considering that some other high-end groupsets can weigh over 3 kilograms!
If you’re looking for the best possible performance from your road bike, then you need a Shimano Dura-Ace groupset. It’s simply unmatched in terms of quality and performance.
Dura-Ace Vs Ultegra
Regarding high-end road bike groupsets, there are two main competitors: Shimano Dura-Ace and SRAM Red. But within the Shimano family, there is another rivalry between Dura-Ace and Ultegra. So which one should you choose?
As with most things in life, the answer is that it depends. Here’s a rundown of the key differences between these two groupsets to help you decide.
Dura-Ace vs Ultegra: The Differences
1. Weight One of the key differentiating factors between Dura-Ace and Ultegra is weight. Dura-Ace components are generally around 10% lighter than their Ultegra counterparts.
This might not sound like much, but it can make a noticeable difference when climbing hills or accelerating. Every little bit counts when you’re trying to go fast!
2. Materials & Construction
Another area where Dura-Ace has an advantage over Ultegra is in materials and construction quality. Dura-Ace parts are made from higher-grade materials and tend to be better finished overall (e.g., smoother shifting). This results in slightly better performance, though the difference is usually quite small unless you’re a competitive racer striving for every last advantage.
It also means that Dura-Ace components will likely last longer before needing replacement or servicing.
Conclusion
In conclusion, the Dura Ace 7800 is a more expensive option than the 105, but it offers many of the same features. If you are looking for an all-purpose tote bag, the Dura Ace 7800 is a good option.
