Shimano has introduced new components, including an updated Deore group and XT mechanical derailleurs, shifters, and pedals. The new Deore group features cable-actuated shifting and updated brakes, while Shimano also claims to have developed a more durable cassette. It appears that Shimano is continuing to support mechanical drivetrains with these updates, although other companies, such as Microshift, are also releasing new drivetrain options.
