STUDIO COMPOSITE RC-SS EX Concept Destruction for Shimano 55mm #Black/Gold

The R27XXL knob has been redesigned as a long knob that can hold three fingers. Lightweight and highly rigid, the monocoque (hollow structure) carbon knob is coated with a special matte rubber for maximum sensitivity.

Highly bonded 5mm carbon prepreg on 55mm length. The specifications combine sensitivity, delicacy, and strength.
The shaft is the tough 5Φ SUS shaft used in the 5mm-thick RC-SC EX PLUS, combining strength and rigidity to the limit.
