| WEIGHT DISCLAIMER | The most accurate way to determine a product’s weight is to have your local dealer weigh it for you. Because we understand that weight is an important metric, we strive to list it when possible. When listed, weight is based on a single sample in a specific size and with all items as shown in the photo. It is not an exact indication of what your bike or frame will weigh, as there are tolerances in many variables involved (size, finish, hardware, components, and accessories). Felt continues to be an industry leader in weight and performance. | SPECIFICATION DISCLAIMER | Specifications subject to change without notice. |
