GIRO Aerohead MIPS time trial helmet Black Giro Aerohead MIPS time trial helmet Black / Titanium, Size L (59-63cm), new but unused. Purchased new in May 2025 from the bike INN website. It cost ¥41,546 including shipping, and it took about two weeks to arrive as it was an imported item. It has been used in triathlon races and for riding, so there is some dirt as shown in the photos, but it can be removed with polishing. There is no damage to the helmet body or visor, so there are no problems with its use. It will be packed in a cardboard box with cushioning material to prevent breakage. 100 size (width 43cm, depth 29cm, height 28cm), weight 1.6kg
