91 mountain helmets tested by VT (21 5-star), best STAR score 6.82.
Every mountain helmet in the Virginia Tech Helmet Lab's STAR registry (91 of 304 tested), sorted by STAR score (lower is safer).
| Lower is better — VT's predicted-concussion-risk score. Not a percentage. | VT's 1-5 star bin for the STAR score; 5 = best available, 0 = lowest-scoring tested helmets | VT's own category — Road, Mountain, Urban, Multi-sport (commuter/rec), Full-Face | MIPS or equivalent — derived from model name only, not independently verified | Safety standards met; CPSC is the US baseline floor nearly every row meets | VT's listed test-time price — street estimate, verify before publish | ||
