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.

Are Dura-Ace and Ultegra cassettes interchangeable?

Shimano's Dura-Ace and Ultegra Di2 components are highly interchangeable provided they all bear the company's e-tube technology (the one exception being the original Dura-Ace 7970 groupset, which uses a unique wiring harness).

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.

Which is better Dura-Ace or Ultegra?

Although Dura Ace is considered to Shimano's out-and-out performance groupset, surprisingly, Ultegra is generally deemed to be much more versatile, mainly because of the lower range of gears that it offers. While Ultegra cassettes go all the way up to 34 teeth, Dura Ace cassettes only go up to 30 teeth.

How much lighter is a Dura Ace cassette?

If you compare the weight difference for the whole cassette, the Dura-Ace cassette is lighter than the Ultegra cassette by 64 grams, out of which 61 grams comes from the last 5 sprockets.

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.

Are Dura-Ace pedals worth it?

Serviceability, low weight, durability, and ease of finding spares all add up to a flagship product that is easily one of the best road bike pedals on the market, and since Shimano components can often be found with great discounts online, you'll likely be able to buy them for cheaper than the competition too.

Can you mix Ultegra and Dura-Ace 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!

Can I use an Ultegra cassette with 105?

There's no reason why you can't use an Ultegra cassette with an otherwise 105 groupset, or vice versa. With both 105 and Ultegra, the largest sprocket you can officially use is a 34-tooth, although in truth you can go much larger than that; we have gear systems with 11-40 cassettes that work very happily.

Is Ultegra worth the money over 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.

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.

How long does a Shimano Dura-Ace cassette last?

Lifespan is hard to predict... The life of any cassette depends on riding conditions and how often you maintain your bike and replace your chains. If you replace your chain at 1,500 miles (use inexpensive chains), your cassettes won't wear as fast.

Does Campagnolo cassette work Shimano?

Yes. Campagnolo wheels are compatible with both Shimano and SRAM components. In order to use Campagnolo wheels with any drivetrain on the market, Campagnolo produces two kinds of freewheel bodies: one specific for Campagnolo drivetrains (from 9 to 11 speeds) and one for non-Campagnolo drivetrains (from 9 to 11 speeds).

Can you put an 11 speed cassette on a 10 speed bike?

Luckily, many common and not-so-common wheelsets, as long as they're at least 10-speed, can be upgraded to 11-speed by purchasing a new cassette body.

Will 10 speed shifter work with 11 speed cassette?

No, that will not work. The shifts will not line up across the entire range, because an 11-speed cassette is not just a 10-speed cassette with an extra cog stuck on at the same spacing.

Are Ultegra brakes better than 105?

Ultegra dual-pivot brakes are slightly lighter in weight compared to the Shimano 105. The hydraulic disc brakes are constructed with engineered composite making them lighter by a few grams compared to the 105 sets. Braking's performance is as good as the Shimano 105.

Can I use Dura-Ace shifters with Ultegra derailleurs?

This means that all of the road bike Ultegra/Dura-Ace dual control brake levers/shifts, time trial shifters, and climbing shifters can be used with either Ultegra 6770/6870 or Dura-Ace 9070 front and rear derailleurs. Any of the Ultegra/Dura-Ace controllers (A Junctions) can be used with either system.

What is the difference between Ultegra Di2 and Dura-Ace Di2?

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 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.

Do Dura-Ace pedals come with cleats?

A pair of Shimano's blue-tipped SPD-SL cleats are included in the box, offering a middling (+/- 2°) amount of float (the amount your feet can move while remaining clipped in).

Who purchased speedplay?
