The board ranks 13 bike helmets from S (best) to F (avoid), last researched 29 Aug 2026, drawing on 116 outlet citations across the board. Placed in the bottom tiers as ones to avoid: POC Cularis, Giro Eclipse Pro, Trek Starvos WaveCel, and 3 others.",

Every run ranks a board of candidates that deliberately includes products buyers cross-shop but should avoid. Placements score on a ranked ladder (LP), and tiers are derived from LP, so no tier is ever assigned by hand.",
