They?re alright. Overall, I am disappointed but remain hopeful for future drops. I have several of these, different styles. Very simple, very versatile, can do multiple different axle types. The rotation has good resistance and doesnt feel like it will wear out. Wife says super super confortable. I wanted to like this product but I can?t. (Bios Update nicht vergessen)Für mich lohnt sich der Umstieg allerdings einfach nicht. Just an all around disappointment. I loove it!
