The Chorus Skeleton calipers are identical in design to the Record Skeleton calipers. They went through the same weight loss, they have the same enhanced rigidity under load, and they have the same differentiated design that makes the rear caliper 40g lighter than the front. Even after giving a set of Chorus calipers a long inspection, you'd think they're Record thanks to their elegant construction and their distinctive use of recessed pivots. All that separates them from the Record is the lack of titanium and alloy hardware. They're 36g lighter than the pre-Skeleton Chorus design, weighing in at 326g.
