Fit & compatibility notes
Fit note
77-LED turn-signal matrix
Front-and-rear LED clusters shine the matching side momentarily for a true turn signal — visible from a 90° angle at the crosswalk gap.
Fit note
MIPS rotational-impact protection
MIPS low-friction layer addresses the rotational-impact case the standard bike helmet tests miss — meaningful at the higher closing speeds e-bike commuters ride at.
