What year is Dura Ace 7900?

2008
In 2008, Dura-Ace 7900 was launched, a radical redesign and new aesthetic direction over the previous version, gunmetal grey replacing polished metal. A year later Shimano went electronic, introducing its first Di2 (Digital Integrated Intelligence) groupset with Dura- Ace 7970.

How many miles does a Dura Ace cassette last?

I usually get about 2500 miles per Dura Ace chain, and swap the cassette on the fourth chain, at 9-10,000 miles.

Is Dura Ace made by Shimano?

Update 31/08/21: Shimano has now officially launched the new Dura-Ace groupset. Team DSM, which was Team Sunweb prior to the 2021 season, has a long-standing relationship with Shimano, so it’s not surprising to see the new groupset make its first official public debut on the team’s bikes.

Is Dura Ace more durable?

Dura Ace is less durable than Ultegra. Dura Ace is designed with low weight as the primary consideration. Good design mitigates this to some degree, but if 1/2 pound does not matter to you, and you want the set that will last longer and perform more consistently over time, then you want Ultegra.

What is the difference between Dura Ace 9000 and 9100?

Visually, there isn’t much to differentiate the new Shimano Dura-Ace 9100 shift levers from the previous 9000-generation. Internally, though, shift lever throw has been reduced by nearly 25% for faster shifts and less hand movement, especially when making multiple shifts.

Who owns Dura Ace?

We take years to give you seconds. The pinnacle of Shimano technology and innovation, the new 12-speed R9200 DURA-ACE is our fastest ever. Speed was the driving force behind this next-generation road group.

How many miles should an Ultegra chain last?

Varies widely depending on riding habits, environment and maintenance. But if all these conditions are average, a 10-speed chain should last around 3,000 miles, with the cassette also ready for replacement at the time you install the third chain.

Can I use Ultegra cassette with Dura Ace?

Thus, an Ultegra (6800/8000) 11-speed chain can be used with a Dura-Ace (9000/9100) 11-speed cassette. Similarly, there is no need to match the level of the chain and cassette to the rest of the groupset, so a 105 (5800) 11-speed cassette can be used with a Dura-Ace (9000/9100) 11-speed groupset.

Which is better Shimano Ultegra or Dura Ace?

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.

Is the Shimano cs-7900 Dura Ace cassette good?

Overall, this is a good cassette. With the new CS-7900 group Shimano answered a demand for wider range or gears. I used to have CS-7800, which only had 12-27 teeth cassette. Now I upgraded to 11-28 teeth, which makes it perfect for hill and mountain road rides.

Which is better Shimano Dura Ace or 7800?

Shimano Dura-Ace 7900 offers a variety of notable improvements over 7800 such as the absolutely fantastic front shifting and superb brakes. Weight weenies will also herald the 112g decrease for the complete group.

Can a Shimano 7900 be used with a 7800 derailleur?

Shimano say the revised cable pull ratios on 7900 essentially make backwards-compatibility with 7800 brake callipers and front derailleurs a no-no. Sadly, we’ll have to mostly agree. Mixing brake components yields either a too-firm lever with reduced power (7900 levers with 7800 callipers) or a somewhat spongy lever with grabby response.

How big are the cogs on a Shimano cassette?

Dual, 6-arm aluminum carrier design reduces weight and increases stiffness. 5 largest cogs mounted to carriers with 4 largest cogs in titanium. 163g @ 11-23t. Video Player is loading. This is a modal window.
