Thousand Chapter MIPS review

The Chapter MIPS is built for the commute that ends with a walk: you lock the bike, and the helmet locks with it. Thousand's Secret PopLock is a hidden channel behind the logo that takes a U-lock or chain lock, and the company backs it with an Anti-Theft Guarantee. Safety features include integrated MIPS and certification to CE and CPSC cycling standards, and a 30-lumen magnetic taillight ships in the box, running 1 hour solid or 2 hours flashing. An integrated dial and a one-handed magnetic fastener make it quick to put on, and visors in several finishes cut glare. Thousand lists 8 vents with internal channeling and weights of 360 to 410 grams by size. The tradeoffs: it is heavier and less ventilated than the road helmets here, the light's runtime suits short trips, and the $149.95 price is more than double the Align II. Thousand's cheaper Heritage 2.0 at $99.95 drops MIPS.
