Shimano has released a special edition of its CUES groupset with a polished silver finish, which can be used for 1x 10- or 11-speed builds. The polished silver option is part of the CUES lineup, although it is unclear if this finish is exclusive to the CUES or also available on other Shimano groupsets, such as GRX. The release appears to be part of a broader trend of polished aluminum making a comeback in the cycling industry.
