According to the product specialist
Pros
| Great shifting performance: quick and smooth shifting even when you're standing on the pedals. |
| Amazing modulated braking power without abrupt clamping of the brakes. |
| Semi-wireless: there's only a cable connection between the battery, front and rear derailleur. This makes for easier mounting and a low chance of cable breakages. |
| You can bleed the brakes without unscrewing the caliper from the frame. Pretty convenient! |
| The derailleurs only need to be finetuned once thanks to Di2 electronic shifting. After that, you'll be ready for the rest of your road bike's life. |
| This upgrade kit enables you to replace only the essential components of your bike. |
| The upgrade kit allows you to adjust your bike's drivetrain to your liking |
| Sram eTAP AXS offers unparallelled possibilities on and next to your bike! |
| The wide range of this 12 speed groupset is well suited to all surfaces and environments. |
| No more chain slap thanks to to the innovative Fluid Clutch. |
| You can customise this groupset to your preference. |
| The groupset has many of the properties of the pricier Red AXS. |
| You can switch the parts of the groupset with SRAM Red and SRAM Eagle AXS parts. |
| Precise shifting performance and high speed shifting, even when standing on the pedals. |
| The brake lever is adjustable and the rotors are less prone to rubbing, improving your control while braking. |
| Semi-wireless, with only one cable between the battery, front and rear derailleur. Easy to install and low risk of cable failure. |
| You can bleed the brakes without dismounting the caliper from the frame. Pretty convenient! |
| You'll only need to position your derailleurs once, and then you're ready for the rest of your road bike's life. The shifters' battery life lasts an impressive 3 years. |
Cons
| Ultegra R8100 Di2 Disc is not the most lightweight groupset, and is heavier than Shimano Dura Ace R9200 Di2 Disc. |
| The front derailleur shifts less smoothly when the ratio between the front chainrings is different than 13 teeth. |
| Cheaper materials make this groupset heavier than the Red AXS groupset. |
| You need a special XDR body on your wheel to mount this cassette. |
| The Shimano 105 R7100 Di2 Disc groupset uses relatively heavy materials in its components. This is reflected in the total weight of the groupset. |
