*In the bicycle industry, suppliers and factories sometimes change specs without notice and state that they are "subject to change without notice". This is because bicycles are made from hundreds of parts which come from dozens of vendors. Parts are sometimes updated to the most current production generation/iteration one gets better or more current parts or a comparable part. Product specifications are subject to change without notice.
