Halfway between the Standard tire (35 mm) and the Balloon tire (50 mm), the Semi-Balloon (42 mm) strikes the perfect balance between comfort and lightness.
This is the most common tire for 650B rims.
650B tires are designed to fit rims with an outer diameter of 595 mm from rim to rim. Be sure to check the size of your wheels before placing an order.
The bestseller: the white or red 650B Semi-Balloon tire!
In the second half of the 1920s, some manufacturers began offering 650 Balloon tires with a 50mm width to provide greater comfort compared to 700 Standard tires with a 35mm width.
A few years later, a compromise between standard tires and Balloon tires emerged: the 42mm-wide Semi-Balloon tire.
It began to gain popularity in the early 1930s and became the dominant choice after World War II with the decline of the 650B Balloon tire.
Many manufacturers also prefer it over 700B Standard tires because it allows for more compact, lighter frames with better performance.
Still considered the perfect balance of comfort, performance, and lightness, it is the tire of choice for many cyclists.
This model features a "striped" tread pattern. In addition to offering a sleek and elegant design, this also ensures excellent rolling performance.
This tire model features asymmetrical sidewalls. On one side are the BERGOUGNAN markings and the tire size. On the other side are the drive ribs for a dynamo. You can see this side in the gallery above, mounted on a black rim. It has no specific direction of rotation; you can mount it either way, depending on whether the dynamo is on the right or left.
Our 650B Demi-Ballon tire is available in three colors: white, red, and black.
The white 650B Demi-Ballon tire will add a touch of elegance to your vintage bike. In red, it will give it a sportier look. Finally, the black version, which is more understated, will highlight your bike’s frame and accessories. It’s often the best choice when paired with a light-colored or brightly colored enameled frame.
