According to the product specialist
Pros
| Great shifting performance, high shifting speed and smooth shifting even when you're standing on the pedals. |
| This cassette contributes to 1/3 of the gear shifting speed compared to the 11 speed Shimano groupset. |
| The sweet spot between the 6th, 7th and 8th sprockets has been taken into consideration while developing this cassette. |
| 11-44T with a 400% geare range to be used with a single front chainring. |
| Suitable for Shimano Race HG 10-11 speed bodies as found on the majority of race and gravel wheels. |
| Compatible with Flattop chains for a unique look and better performance. |
| Reliable shifting performance and high shifting speed even when you're standing on the pedals. |
| This cassette contributes to reducing shifting speed with 1/3 compared to the 11-speed Shimano groupset. |
| When developing this cassette, Shimano took the 'sweet spot' between the 6th, 7th and 8th sprockets into account. |
| Suitable for mechanical as well as electronic groupsets. |
Cons
| Compared to the Shimano Dura Ace R9200 12 speed cassette, you compromise somewhat on durability and weight. |
| Does not fit Sram XDR bodies. |
| Only works with SRAM flattop chains. |
| As the 105 cassette is ground using Hyperglide technology, it shifts slightly slower than the Ultegra and Dura-Ace 12-speed cassettes, on which the Hyperglide+ technology is used. |
