According to the product specialist
Pros
| Great shifting performance, quick and smooth shifting 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 less chance of cable breakage. |
| You can bleed the brakes without unscrewing the caliper from the frame. Pretty convenient! |
| The derailleurs only need to be adjusted once thanks to Di2 electronic shifting. After this, you'll be ready for the rest of your road bike's life. |
| 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, just a cable between the battery, front and rear derailleur. Easy to mount and low risk of cable failure. |
| You can bleed the brakes without dismounting the caliper from the frame. Pretty convenient! |
| One time only positioning of the derailleurs and you are ready for the rest of your road bike's life. The shifter's battery life lasts an impressive 3 years. |
| This groupset gives you almost the same experience as SRAM Force eTap AXS, but at a more affordable price! |
| This groupset has a very wide range, so you can cycle away both in the mountains or on flat embankments. |
| You can personalise the control of the groupset by using the SRAM AXS App on your smartphone. |
| Wireless groupset, making it easier to mount than a groupset with shifter cables to the derailleurs. |
| You get more consistent gear intervals thanks to the X-Range technology, making it easier to find the right gear. |
| This groupset gives you the same performance as Sram Red eTap AXS, but at an affordable price! |
| This groupset has a very wide range, so you will always find the right gear! |
| You can fully customise control of the groupset using the Sram AXS App on your smartphone. |
| The parts in this groupset are interchangeable with other AXS parts, including the Eagle AXS. |
| Fully wireless and therefore much easier to assemble! |
Cons
| Ultegra R8100 Di2 Disc is not the most lightweight groupset, and is heavier than Shimano Dura Ace R9200 Di2 Disc. |
| The Shimano 105 R7100 Di2 Disc groupset uses heavier materials in its components. This is reflected in the total weight of the groupset. |
| You need an XDR body to install the cassette. |
| This groupset is slightly heavier than groupsets from the higher price segment, because less expensive materials have been used. |
| You need an XDR body to install the cassette. |
