The parallelogram suspension of Suntour seatpost has so many bearings that are exposed and thus are exposed to dust and dirt. Therefore, I have these finger guards ordered the same together with the seatpost. At the latest after the fourth attempt you will notice that the elastic fabric am extremely excited about the camp must completely enclose. Once attached, the fabric wraps but perfect the movable spring elements. I am happy with the purchase and may the "Finger Guards" necessarily a useful accessory highly recommend.
