Pike - Not afraid of the rooty chutes. Unintimidated by the calf-crushing climbs. A fork designed to level up your trail game. Charger 3.1 with increased damping range and High Speed Compression, Low Speed Compression, and Low Speed Rebound adjustments ButterCups block 20% of high-frequency “trail chatter”. Limiting these vibrations massively reduces hand and arm fatigue leaving you feeling fresh with more control. DebonAir+ air spring is built to strike the perfect balance of what riders really want: a butter-like small bump feel, increased air volume to add support throughout the travel, and higher overall ride height for more confidence when things get steep. Ultra-low friction SKF wiper seals provide long lasting fork performance and improve overall suspension feel. Short fender compatibility.
