- Not noisier than the summer hakka green 2, they make noise only when accelerating (the work of the lamellas is expressed, a slight heavenly rustling). Strong. I got into pits / crooked manhole covers, everything is ok. In the snow they row with dignity, on clear ice they are a little worse than spikes. More details in the comments.
- I don’t know about other Velcro, but these ones lost 1.5-2 mm on the drive axle in one winter season (about 10 thousand km, highway / city). I will write down the shortcomings, but I think this is the norm for soft rubber.
