26-inch wheels were popular on mountain bikes for many years and were the standard for mountain bikes. However, they have become less common in recent years as larger wheel sizes, such as 27.5-inch and 29-inch, have become more common. However, some older mountain bikes and some specialized uses still use 26" wheels. Dirt jump and BMX, freeride and downhill bikes use 26" wheels, which are suitable for these disciplines, as the smaller diameter provides greater agility and control, which is essential for tricks and jumps.
Larger wheels are often preferred for their ability to overcome obstacles more easily and maintain momentum, especially when riding off-road and on trails. As a result, the availability of tires and other components for 26" wheels may be more limited compared to larger sizes.
What are the main disadvantages of 26" rims in mountain biking?
Although 26" rims were a popular choice for mountain bikes in the past, they have some disadvantages compared to newer rim sizes. Here are a few disadvantages of 26" rims:
- Limited availability: As newer rim sizes like 27.5" and 29" have become more common, the availability of 26" rims and tires has decreased.
- Reduced rolling efficiency: Larger rim sizes, such as 27.5" and 29", offer better rolling efficiency and momentum retention. This means that 26" rims may not roll as smoothly over rough terrain and may require more effort to maintain speed and momentum.
- Reduced traction and stability: Larger rim sizes generally provide better traction and stability due to a larger contact patch with the road. This can be especially noticeable on challenging terrain, such as loose or technical trails, where 26" rims may not provide the same level of grip and control.
- Less obstacle clearance: A smaller diameter can make it more difficult to overcome rocks, roots, and other obstacles on the trail.
- Limited compatibility: Some newer mountain bike technologies and components, such as some suspension systems and frame designs, may not be compatible with 26" rims.
Is weight a consideration when choosing 26-inch mountain bike rims?
Yes, weight is a consideration when choosing 26-inch mountain bike rims. The weight of the rims can affect the overall weight of the bike and can affect its performance. Lighter rims can make the bike more agile and responsive, especially when climbing or accelerating. However, it is important to find a balance between weight and durability. Extremely light rims can come at the expense of strength and durability, which can lead to an increased risk of damage or failure when riding in difficult terrain. The average weight of a 26-inch mountain bike rim ranges from 400 to 700 grams.
What materials are commonly used to make 26" rims?
The following materials are commonly used for 26-inch rims:
- Aluminium: Popular due to their weight, durability, and affordability. They provide a good strength-to-weight ratio and are suitable for most riders and terrains.
- Carbon fibre: Known for their exceptional strength, stiffness, and light weight. They offer increased performance and responsiveness, making them popular with professional riders or those looking for top-notch performance. However, they tend to be more expensive than aluminium rims.
