Specifically developed for the rigours gravel riding, this versatile suspension fork features 30mm straight wall aluminium upper tubes for maximum strength and durability on every mile. RockShox has also equipped this model with magnesium lower legs for additional stiffness, while also keeping its overall weight reduced. This means that riders will enjoy its superior strength to weight ratio wherever their next adventure takes them. Solo Air Spring and Charger Race Day Damper Whether you're wanting to explore the countryside back roads further or planning an epic weekend gravel adventure, this fork is kitted out with some of RockShox's finest technologies to make the ride comfortable, smoother and more rider-tuned. Its Solo Air spring is tuned for short travel, which makes it ideal for handling mixed terrains and mountain gravel road climbs. Another benefit is its adjustable Charger Race Day damper that provides a rock-solid lockout and a full range of rebound adjust. As a result, riders can use its external rebound and two-position (open/lock) compression to dial in their preferred settings to match their riding style as well as the terrain conditions.
