According to Shimano's figures, the new Dura-Ace groupset without wheels weighs a total of 2,438g with the regular non-power meter chainset, compared with Ultegra R8100's 2,716g, a difference of 278g. The previous R9100 Dura-Ace Di2 was slightly lighter at 2,403g while Ultegra R8000 was 2,705g, a difference of 302g.
Is Dura Ace Di2 better than Ultegra Di2?
It also means that Dura-Ace Di2 will age better than Ultegra Di2, keeping that new-bike feeling far longer into its life. So if you ride your bikes for 10 years, and expect to keep the same group that whole time, Dura-Ace Di2 may be the way to go. Second, Ultegra Di2 is a bit heavier, but not by much, as noted above.
What is better Ultegra or Dura-Ace?
Even if you are a serious racer, the Ultegra is a great option. The Dura-Ace, however, is an incredible groupset. Its performance is unrivaled and, despite the cost, there is a reason it's a go-to for pro racers. If a few grams of weight doesn't matter to you, opt for the Ultegra.
What is the difference between Dura-Ace and Ultegra cassette?
Ultegra is a groupset designed to be used for a variety of riding styles. To this end, Ultegra can now accommodate a 34t cassette, whereas Dura-Ace tops out at a 30t. Similarly, the Ultegra rim brakes are heavier because they have to be larger to accommodate 28mm tyres, which means more materials and extra weight.
Can you mix Dura-Ace and Ultegra Di2?
Di2 Compatibility - mix Ultegra, DURA-ACE, XTR, XT and GRX components. Did you know most 10-speed and 11-speed Di2 hardware is cross-series compatible? You can actually mix different series and even different generations of Di2 hardware, as long as you make sure you follow the Di2 compatibility chart!
24 related questions foundWhat happens when Di2 battery dies?
It doesn't switch back to mechanical when the battery dies
SRAM Red eTap has a slight back-up in that the batteries are interchangeable, so if the rear mech goes you can borrow the battery out the front and hopefully have enough shifts to make it home.
Is Ultegra Di2 lighter than mechanical?
For high performance bikes these days, half a pound is a lot. This being said, the Ultegra Di2 is only 80 grams heavier than the mechanical Ultegra group, so the weight penalty for going to electronic shifting is minor.
Is Ultegra R8000 Di2?
The new Ultegra R8000 series is taking our rider-tuned philosophy to the next level, with an extensive range of components for mechanical shifting, electronic shifting (Di2) and time trial / triathlon.
Does a Dura Ace cassette last longer than Ultegra?
If the Durace has better longevity, I might be willing to pay for the pricier cassette to save a couple of grams. A Dura Ace cassette will not last longer, in fact the titanium cogs will wear more quickly. If longevity is the goal, then Ultegra is the answer.
Is Dura-Ace less durable than Ultegra?
This is good news for the consumer because it means the two can be directly compared right from the start - which is exactly what we plan to do here. Dura-Ace has always been the flagship Shimano groupset - lighter, more durable, and very expensive. But in performance terms, Ultegra has started to close the gap.
Is Ultegra more durable than 105?
Conclusion. There is no longer any real technological difference between 105 and Ultegra, and the only real difference is that Ultegra is a lighter groupset.
Is Dura-Ace the best?
Two years, over 10,000 miles, one conclusion: Shimano's Dura-Ace 9000 mechanical group is the best human-powered drivetrain the world has ever seen. If you're a weight-weenie, look to SRAM, home of the best weight/cost ratio in the industry.
Why is Ultegra better than 105?
There is a difference in the materials used. Ultegra dual control levers have carbon-fibre reinforced plastic brackets and main levers while 105 has glass-fibre reinforced plastic brackets and aluminium main levers. The 105 levers are a little heavier but you won't notice any difference in performance.
How long does Dura Ace Di2 battery last?
A modern Di2 battery will last between 2000 and 5000 kilometers per charge. This depends a bit on how often you shift and also your shifting style. The front derailleur has to work harder than the rear derailleur and therefore also consumes more energy.
How much does a full Di2 cost?
An Ultegra Di2 front derailleur will set you back about $560, while Dura-Ace Di2 is about $780.
Is Ultegra only Di2?

How many miles can a Dura Ace cassette?
If those cogs are used a lot, they will wear out quickly. I've had severe wear on Ti cogs after only 4,000 miles of use. With a steel cog cassette, I expect it to last trough the life of the 3-4 chains in a rotation. With Shimano chains that might only be 9-12,000 miles.
Is Shimano 105 good enough for racing?
105 is the first of Shimano's “serious” or “proper” groupsets. Tiagra and below, despite being perfectly adequate for your first few sportives (probably all your sportives) and for your daily commute, should be eschewed in favour of 105 or Ultegra as soon as your functional threshold power hits 150W.

Wireless Unit (DI2 spec.)
Is Ultegra R8100 wireless?
The new Ultegra R8100 is electronic-only and, in the disc brake version, wirelessly communicates gear-change inputs from the shifters while maintaining a wired connection from the rear derailleur and front derailleur to a battery mounted in the seat tube.
What is Ultegra Di2?
Ultegra Di2 6870 combines newly designed dual control levers and smaller, ligher, derailleurs and a new internal seatpost battery, and uses the same chainset and caliper brakes as the mechanical Ultegra 6800 groupset.
Is Di2 worth the money?
If you have the money and you ride a lot, yes. It is so worth it. I'm big fan of Di2, but it's a luxury. You probably won't enjoy the ride anymore than mechanical, unless you enjoy useful gadgets and tech for their own sake.
What is the advantage of Di2?
The advantages of mechanical-free, electronic gear shift systems like Shimano's Di2 and Campagnolo's EPS include more precise, quicker gear changes, reduced chain wear, and the facility to allow multiple locations for shifters, making the process of swapping cogs as simple as the press of a button.
Do Tour de France riders use electronic shifting?
