Different wheel sizes give you the freedom to run whatever size or type of tire you wish. That’s why we made the Broam compatible with both 650b and 700c wheel sizes. The Broam comes standard with 700c hoops, the traditional size for road bikes. They can accommodate up to 45mm-wide tires, giving you the versatility to select your optimal rubber for whatever route you have in mind. If you opt to switch out your stock wheels for a set of 650 alternatives, you can fit tires that are up to 2.1 inches wide.
