Shimano Introduces 12-Speed Disc Brake Only 105 Groupset

Shimano has announced the release of the new 105 mechanical groupset, featuring a switch from 11-speed to 12-speed and disc brakes only. This follows the trend of Shimano's higher-end groupsets, Ultegra and Dura-Ace, which have transitioned to electronic-only versions. The new 105 groupset offers similar features to its electronic counterpart, including chainset and cassette options, brake calipers, and rotors. The shifters and derailleurs have been updated, with a refined lever shape for improved reach. The groupset is priced at around £750 / €1150 / $1150 for a full set.
