Item # GIR00DF


Don't overthink it.

You don't have a full race calendar or a spot on the local cycling team, so gear should be more about function than style. Open, empty roads and long sojourns on Sunday afternoons are where you find your joy in cycling, and gear that helps you stay out longer always ends up being what you reach for first. The Giro Cinder MIPS Helmet fits that description aptly, so if your old lid has seen better days, protect your grey matter and stick to your principles by upgrading.

Inspired by the competition-minded Synthe, the Cinder shares more than just a similar sounding name with its pricier sibling. Giro anchors the Cinder with a streamlined, aerodynamic shell much like the Synthe's, and ensures it maintains ample airflow out on the roads by carving 26 vents into its shell. Its light, unfussy design succeeds just as well in weekend fondos as it does on weeknight group rides, while inside the helmet, a MIPS liner adds subtle, but important protection. MIPS, or Multi Directional Impact Protection System, refers to the Swedish technology that appears in the form of a thin inner basket, which rotates upon impact to absorb brain-damaging rotational energy generated in certain crashes. The fifth version of Giro's tried-and-true Roc Loc 5 fit system makes lateral and vertical fit adjustments easy to do with one hand, while Air-Fix padding and a ponytail-compatible design give the Cinder an adaptable, versatile fit.

  • Protect your brain with this classic, lightweight helmet
  • MIPS technology reduces brain-damaging forces in some crashes
  • Capable In-Mold construction lends impact protection
  • One-handed fit adjustment makes on-the-go tweaks easy
  • Wealth of vents keep air moving while you're riding

Excellent Pricing on a Quality Helmet

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Large

This helmet was my 1st purchase with Competitive Cyclist. I was able to snag the helmet at a 50% savings. It shipped and delivered as promised.

Fit is great and provides enough room for a winter shell and sunglasses. This is a MIPS system and worth the step up in safety.

I highly recommend Competitive Cyclist. Great pricing on a consistent basis.

Very Nice

  • Familiarity: I've used it several times

I really am pleased with this helmet. I have 3 different brands the straps on the Giro are the best. MIPS is very comfortable.

great helmet

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: medium

Wanted to try a MIPS helmet, also like that this doesn't have the long "duck tail"/aero back end to it like most helmets. Light, looks good and vents well. Fits true to size and price and service were great.

Great Helmet

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

Excellent construction, and good looks, if you are on the edge of a size if you can try the helmet somewhere before you buy it will be preferable
