What are the key features to consider when choosing a front fork for a mountain bike?

When choosing a front fork for a mountain bike, key features to consider include travel distance, damping system, stiffness, weight, and wheel size compatibility. Travel distance refers to the amount the fork can compress and is important for different types of terrain. The damping system controls how the fork absorbs impacts and maintains control. Stiffness affects handling and responsiveness, while weight can impact overall bike performance. Compatibility with your wheel size ensures proper fit and function.
