The Maple Wheels Bowls are handmade in Quebec, Canada, with care and passion reflected in the wheel's quality. The Bowls are Maple's largest wheels currently and come in at 9mm in diameter and 5.5mm in width. They're constructed out of urethane and feature a 70D durometer. They also come with ABEC-9 bearings that are locked into the wheel, making them have less chatter/wobble.
