29″ MTB is also known as 29er. It is 3 inches larger than the traditional 26″ mtb wheel size. When come across of performance of the bike whether 26″ and 29″ wheel size, it is always come to the debate among the cyclists. Different cyclist has different experience, views and perceptions. If you are good in physics/science, you may know the pros & cons of riding 29″ MTB bike. Let’s see what are the pros & cons of 29er MTB.
- Larger wheels roll over obstacles more easily due to decrease in approach angle
- The larger diameter wheels have more angular momentum so they lose less speed to obstacles and rough sections
- 29″ bikes tend to offer taller riders a more “natural” frame geometry
- Increased wheel weight and rotating mass (the spokes, rim, and tire are all larger) makes the wheels harder to accelerate and harder to brake
- More force needed to change steering angle due to greater mass and longer contact patch.
- Longer spokes and decreased angle between hub flange and rim result in a more laterally flexible wheel (all else equal).
- Many types of bicycle tires, tires, rims, forks do not come in 29″-compatible versions, though the expanding popularity of the size is reducing this problem.
