Built for the best riders, ridden on the hardest tracks, ZEB Ultimate rules the world’s toughest enduros. 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 butterlike 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.
