Ace Low Classics are tried and true are a full (4mm) lower than the Classic. Recommended for use with 53mm wheels and smaller. These lower your centre of gravity for added stability and a slightly reduced turning radius. Industry-first features such as oversized axles and beveled hanger ends, both for better bearing performance. Made using industry standard 7071 alloy and 3056 steel axles, you can trust Ace Lows Classics to perform in the clutch.
