The gears at the front provide large jumps, which effectively change the range of your gears, so they are more suited to high-speed, flat-terrain or low-speed climbing. The cassette enables you to select your gear more precisely within that range as you modulate your effort. Automatic transmissions are complex systems that facilitate efficient power transfer and seamless gear shifting in modern vehicles. Among the key components that make this possible are planetary gears, which operate on intricate mechanical principles. In this comprehensive article, we will delve into the fascinating world of planetary gears, exploring their structural composition, working principles, modes of operation, advantages, common maintenance issues, and potential future advancements in automatic transmissions. Buy Shimano Dura-Ace R9200 Di2 if you want the state-of-the-art Shimano (and arguably the overall state-of-the-art when it comes to shifting speed and customisability). As you come to a tight corner, anticipate that you will need to slow down and shift into a lower gear so you can accelerate out of the corner more easily.

The bike may also have a front derailleur, which shifts the chain between chainrings, which are part of the crankset. If you don't want electronic shifting and prefer rim brakes, you're probably better upgrading to the newer 12-speed 105 mechanical groupset; but there is still availability of Shimano's previous generation R8000 11-speed groupset with rim brakes (and disc brakes in various places) and it's usually cheaper, so we're keeping it in this groupset guide for now. As explained in the full article above, CUES (which stands for Creating Unique Experiences) will see Shimano amalgamate its mid and budget-range city, touring and mountain bike groupsets (everything with flat bars essentially) into one family of interchangeable 9-speed (U4000), 10-speed (U6000) and 11-speed (U6000 and U8000) components. This means that parts can be mixed and matched, which should make sourcing and fitting replacements much simpler. There are no rim brakes in the range, just hydraulic disc brakes, and you can either have a single chainring or a 2x set-up, leaving no room for the almost extinct triple chainset.

With an identical feature set to Dura-Ace R9270 Di2, the latest Ultegra is less a budget performance groupset and more a sort of Dura-Ace SE. In the past Ultegra offered a wider range of options than Dura-Ace. For example, you could get an 11-34 cassette where Dura-Ace only went up to 11-30, and there was an Ultegra 14-28 cassette for junior racing that was previously gear-restricted; Ultegra offered a 46/36 chainset for cyclocross racing that wasn't available in Dura-Ace. Now, both groups offer the same options and all the same headline technology.

You used to (and sometimes still do) see a lot of entry-level and mid-range bikes specced with mechanical Shimano 105. It’s the workhorse of the Shimano groupset range and features on bikes covering a really wide price band. Sometimes it gets mixed with other branded parts to meet key price points, but a full 105 mechanical groupset is definitely something to look for, as it really has very few weaknesses. Like the Di2 version, the new Shimano 105 R7100 Mechanical is disc brake-only, and features a redesigned gear range with the ability to accommodate (officially) up to an 11-36T cassette. The wider gearing range is arguably the biggest chance from the 11-speed version, other than the new look and extra cassette cog.

It’s a favourite with amateur racers because the weight penalty is minimal, especially if built onto a decent carbon fibre frame, and the performance is nearly identical. You still get the carbon fibre brake lever as well like you do on Dura-Ace, and the cranks, brakes and derailleurs share the same design as Dura-Ace. If you’re riding up a hill or into the wind, your perceived effort will increase, so it makes sense to shift to a lower gear to account for that. Shimano Ultegra is the company's second-tier groupset, with all the features of Dura-Ace for a bit less money because Shimano uses less expensive materials and surface coatings. It's long been considered the working-man's performance groupset; though you might argue that this new version, with its substantial price hike over its predecessor, yields that title to 105. Your gear development – how far your bike moves with each pedal stroke – is typically described in gear inches, i.e. how many inches your bike will roll forward with each full rotation of your cranks.

DeploymentsShimano's engineers say they've learnt their lesson from the transition from 10- to 11-speed cassettes, which left many riders with collections of wheels that didn't work with the new gearing. They've also admitted that the previous Dura-Ace power meter had accuracy issues. This time, the power meter and crank design teams have worked together to ensure the power meter works properly.
