Mountain bike chainrings are an essential component of any bike's drivetrain system. They are the toothed gears that are mounted on the crankset and work together with the chain to transfer power from the pedals to the rear wheel. Mountain bike chainrings come in various sizes and shapes, and their selection depends on the rider's preference and the terrain they are riding on. Some chainrings are designed to provide more torque for climbing steep hills, while others are designed for high-speed descents. They are made from different materials such as aluminum, steel, and carbon fiber, each with its unique pros and cons. Overall, mountain bike chainrings play a crucial role in ensuring a smooth and efficient ride on any terrain.

Frequently Asked Questions (FAQs)
1. How do I know which chainring to buy?
When buying a replacement chainring for your mountain bike, it's important to consider the bolt circle diameter (BCD) of the crankset. The replacement chainring should have the same BCD and bolt positioning as the crankset to ensure a proper fit. The BCD also determines the smallest compatible chainring size. For example, if your crankset has a 130mm BCD, the smallest compatible chainring would be a 38t.
2. Are oval chainrings better for MTB?
Oval chainrings have been proven to offer some benefits for mountain biking. They can increase force effectiveness by up to 9%, reduce oxygen consumption by up to 7%, decrease ventilation (breathing) by up to 15%, and lower heart rate by up to 10% compared to round chainrings. These advantages make oval chainrings a desirable option for some MTB riders.
3. Why do pros not use oval chainrings?
One reason why some professional riders do not use oval chainrings is the potential impact on the knees. Some riders experience knee pain due to the acceleration and deceleration of the legs caused by the 'whiplash effect' of oval chainrings. As cycling is meant to be easy on the knees, this issue is a significant concern for professionals, leading them to opt for round chainrings instead.
