The rubber stoppers that make contact with the front forks are very cheap. The rubber is ripping and almost chunking off in several places. The forks seem to slip every time the front end is lifted which jams the rubber pieces into the front brake system. The two arms also seem to be different lengths. Only the right arm stabilizes the front end while the left arm just barely touches and supports the fork. Seems to be a design flaw. I would not recommend this product to anyone!
