The Isode II Road Bike Helmet distils Giro's professional road helmet expertise into an accessible sport model designed for serious cyclists entering the category. Its compact, aerodynamic profile mirrors the geometry favoured by elite riders, whilst the lightweight construction and strategically engineered ventilation channels deliver efficient cooling during sustained efforts. The intuitive fit system offers 7cm of dial adjustment, accommodating a broad range of head shapes without sacrificing the refined feel and performance characteristics that define Giro's premium lineage. A gateway to pro-level helmet technology for ambitious road cyclists.

QUICK LINK REMOVABLE VISOR

IN-MOLD CONSTRUCTION — In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.

ROC LOC® SPORT FIT SYSTEM — The Roc Loc Sport fit system offers easy one-handed operation with a 7cm adjustment range. Its confident clicking feel and sound lets riders know that the helmet is adjusting to a comfortable fit. With comfort similar to Roc Loc 5 and ponytail compatibility, the new Roc Loc Sport fit system brings premium function to sport level helmets.

DEEP INTERNAL CHANNELING — Combined with the massive vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power.
