Born from the DNA of Lyrik and Boxxer, RockShox is sending the next generation of long-stroke suspension forks into the race. The ZEB Ultimate is based on a stable 38 mm chassis and has the revised DebonAir air spring. With this fork you can challenge the limits of the rideable and conquer the toughest enduro trails in the world. The Charger 2.1 RC2 damper allows you to quickly adjust your low and high speed compression as well as the rebound. SKF seals and Maxima Plush damping oil reduce friction and noise to a minimum and ensure that your fork functions perfectly over the long term.Features:- 38 mm chassis- DebonAir- Solo Air- Charger 2.1 RC2- SKF seals- Maxima Plush Damping Fluid- Maxle Stealth- Bottomless tokens- BOOST- Torque CapsSpecifications:- Intended use : Trail, All Mountain, Enduro- Wheel size: 27.5 ´´- Material fork crown / shaft: aluminum / aluminum- Material stanchions: 38 mm aluminum, black anodized (Fast Black)- Immersion tubes material: Magnesium cast alloy- axle type : 15x110 mm BOOST floating axle (Maxle Stealth)- Steerer: 1.5 ´´to 1 1/8´´ tapered (40 mm to 28.6 mm with 85 mm transition)- Travel: 180 mm- Spring system: DebonAir- Adjustment of the spring characteristic: yes, via tokens, max. 5 permitted- Damping: Charger 2.1 RC2 (Low / High Speed Compression (compression), rebound (rebound)- Lockout: without- Installation height: 557 mm- Brake mount: PM8, Postmount (min. 200 mm brake disc)- Max. permissible brake disc size: 220 mm- Tire diameter max .: 732 mm (without fender)- Tire width max .: 81 mm (without fender)- Offset: 38 mm
