The Manitou Expert Air Spring System contains a unique balancing valve that equalizes the positive and negative air chambers during the air fill process. This gives the spring rate a consistent feel without any flat or dead spots in the stroke, along with giving riders of different weights the same initial stroke feel.
Variable Terrain Tune (VTT)
Adjustments: 3-Position Compression Adjust - When developing the VTT Pro Damper Manitou set out with a goal to maintain a rock-solid lockout without compromising the open and mid settings. The downside to many dampers with firm lockout modes is that in any position other than lock-out, it reaches some critical shaft velocity that choke off the low-speed flow path. When this happens the damper peaks at nearly the same lock-out force as the locked-out position. This translates to harsh force in the hands and possibly lack of control. The goal with VTT is to eliminate that high-speed spike while maintaining the lock-out force demanded by most XC users. This allows the fork to have a less progressive high-speed response while maintaining some low-speed support without getting wollowy. This is achieved thru independent shim-stacks (one for Lockout, one for the other two positions). By controlling the shim stack through which the oil flow is diverted we can manipulate the characteristic of the damper to be Lock-out, Digressive, or Progressive to meet the demands of the rider and terrain.
When developing the chassis of any Manitou fork the primary goal is finding that perfect balance of weight, stiffness, and reliability. Thanks to our Reverse Arch we are able to position the arch further away from the axle. The lower tire clearance behind the fork relative to the center of the axle allows for a shorter arch which yields 13% increased stiffness compared to a forward arch fork of the equivalent weight. Because of this we are able to use 32mm stanchions to save weight while keeping stiffness closer to that of a larger stanchion fork with a forward facing arch.
