Bike Helmets

Frequently Asked Questions

• What should I prioritize when choosing between a road, trail/MTB, or full‑face helmet?

  Road helmets: low weight (200–300 g), aero shaping and high vent count (20+ vents) for racing; trail/MTB: balanced ventilation, extended rear coverage and an adjustable visor for falls typical of trail/enduro; full‑face: chin bar for DH/bike‑park use and the larger chin‑mouth gap (~30 mm) specified for impact management.
• How do MIPS, WaveCel, SPIN and KinetiCore technologies differ for rotational impact protection?

  MIPS is a low‑friction layer that lets the shell slide ~10–15 mm to lower rotational forces (Consumer Reports notes up to ~43% reduction), WaveCel uses a 3‑D crumpling mesh to manage linear+rotational energies, SPIN uses shear silicone pads, and KinetiCore creates engineered crumple zones — choose the tech that pairs with a helmet’s VT rating and intended discipline.
• What fit features matter most for performance and comfort on long rides?

  Measure head circumference at the forehead and use size ranges (e.g., S/M 52–56 cm, M/L 55–59 cm); prioritize a micro‑adjust dial (Roc Loc/Boa), well‑placed pads, and a secure, non‑slipping chinstrap so the helmet sits snugly without pressure points.
• How do I balance weight versus ventilation for road racing vs hot endurance rides?

  For road racing prioritize lower mass (sub‑250 g ideal) and aero shaping, whereas for long or hot rides prioritize higher vent counts (15–30 vents typical, 20+ for many road helmets) and comfort features — expect road helmets ~200–300 g and MTB helmets ~300–500 g, so choose the balance that matches your event and climate.
