Unleash the Speed of the 29er or Conquer any Terrain with Plus Bikes.

Plus mountain bikes and 29ers are related but not exactly the same. Let me explain the differences between the two.

Tire Size

One of the key distinctions between plus mountain bikes and 29ers is the tire size. Plus bikes typically have wider tires, ranging from 2.8 to 3.0 inches in width, while 29ers have narrower tires around 2.2 to 2.5 inches in width. The wider tires on plus bikes provide increased traction, stability, and a smoother ride over rough terrain.

Rim Width

Along with wider tires, plus mountain bikes also feature wider rims to accommodate the larger tires. These wider rims provide better support for the wider tires, helping to maintain a stable tire profile and prevent tire squirm under heavy loads or aggressive riding.

Wheel Diameter

29ers, as the name suggests, have a wheel diameter of 29 inches. This larger wheel size allows for better rollover capabilities, meaning they can roll over obstacles more easily, improving their ability to maintain momentum. Plus bikes, on the other hand, can have various wheel sizes, including 27.5 inches (also known as 650B) or even 26 inches, but with the wider tires.


Another difference lies in their intended purpose. 29ers are often favored by cross-country riders and those looking for speed and efficiency on smoother trails. The larger wheels help with faster rolling and maintaining momentum. Plus bikes, on the other hand, are designed for more technical and challenging terrain, such as loose or sandy surfaces, rocks, and roots. The wider tires offer increased traction and stability, making them popular among riders who prioritize grip and control over speed.

Frame Compatibility

While 29ers typically have frames designed specifically for 29-inch wheels, plus bikes can often accommodate both 27.5-inch and 29-inch wheels. Many plus bike frames feature adjustable dropouts or frame geometry that allows riders to switch between wheel sizes depending on their preferences and the terrain they plan to ride.


Plus mountain bikes are not exactly the same as 29ers. Plus bikes have wider tires and rims, offering increased traction and stability, while 29ers have narrower tires and focus more on speed and efficiency. However, plus bikes can be built with 29-inch wheels, and they are generally geared towards technical terrain, whereas 29ers are often used for cross-country riding.
