Description
Giro's Synthe helmet set the design standard for their road lineup, and the Cinder MIPS borrows that visual language while hitting a more accessible price point. The compact shape and 26-vent Wind Tunnel ventilation system give the Cinder a profile that looks at home in a fast group ride, while MIPS technology adds rotational impact protection that wasn't available at this price tier a few years ago. If you want Giro's road helmet aesthetics without the flagship price, the Cinder delivers that balance.
The construction combines a hardshell exterior with an In-Mold Hardbody polycarbonate lower wrap, fusing the outer shell to the EPS foam liner. This two-piece approach maintains durability without the weight penalty of a full hardshell design. Inside the foam liner, Roll Cage reinforcement adds a web of structural support that helps the helmet hold together under impact rather than fragmenting. Air-FX padding manages moisture and comfort against your head during long rides in the heat, wicking sweat away from your forehead and temples.
Fit adjustment happens through the Roc Loc 5 system, which remains Giro's benchmark retention design. A single rear dial controls tension, and vertical adjustment lets you tune the fore-aft tilt of the helmet on your head. Both adjustments work one-handed while riding, so you can fine-tune fit without stopping or removing gloves. The system operates independently of the chin straps, meaning you don't need to over-tighten the straps to get a secure fit. The soft rubber over-molded fit belt hugs the back of your head and prevents the helmet from shifting during hard efforts or rough roads.... Read More
