Is MIPS worth the extra cost?

Yes. MIPS and equivalent rotational protection systems address oblique impacts—the most common type of cycling crash—by reducing rotational forces transmitted to the brain. Research shows these systems reduce rotational acceleration by 10-35% in oblique impacts, which can meaningfully reduce concussion risk. MIPS-equipped helmets are now available from $80, making the technology accessible at most price points. Given that brain injury is the most serious potential consequence of a cycling crash, the modest additional cost is well justified.
