Hi Omar... a question; What battery do you use on your helmet for riding at night? I participated in the 2019 PBP with a battery that broke after 850 km non-stop. Which one do you recommend? Another thing... are you taking part in the 1001 miles this year? I do. I'm from Borgo San Lorenzo (FI) if you happen to be in these parts and need even very simple help I'm happy to help you. My tel. 3356485266 Alberto
