The new Speed M-Series 20 frames are the backbone of what may be the fastest BMX bike design ever offered. Pair up one of these babies with a Sinz Elite 20-Mil Carbon Pro fork and Sinz Elite 20-Mil iHub wheels and you the most efficient pedaling BMX bike made.
Can’t get all that right now? Not to worry. The new M-Series 20 frames are designed to work with traditional 10-millimeter axle hubs, too. Each frame includes two sets of chain tensioner blocks that make them compatible with standard, as well as the Sinz Elite 20-Mil iHub wheels. This means you can buy a Speed frame now and use your current parts and upgrade to the full 20-Mil system later.
All Speed Expert XL and bigger frames now feature the 10/20-millimeter-compatible dropout system.
Available in four 20” and one 24” cruiser sizes, the new 10/20-Mil frames have updated graphics like a new head badge and seat and down tube graphics. Each frame includes a anodized, aluminum, 10- and 20-millimeter tensioner blocks and a set of tensioner bolts.
