Rockbros bicycle helmet in size M 55-58cm in perfect condition. Optimal for Gravel, MTB and trails due to improved protection of the back of the head. The shape of the European head is an oval. I've been on 3 trips around the area. From the comments, there is a micro-abrasion along the edge in 8 photos and there may be something else like that. But there are also advantages: an upgrade of the fastener has been made - 6 levels of adjustment. 1 800 ₽
