Manitou R8 Pro 29" Boost
Product information "R8 Pro 29" Boost"
High stiffness combined with low weight: the R8 Pro 29" Boost from Manitou
While the first request from athletes was for a stiff chassis for precise handling on technically demanding XC courses, reducing the weight of this very stiff platform was the secondary priority in the development of the new Manitou fork. No area of the fork was left untouched to ensure that every single gram that could be removed was, while not affecting rigidity or reliability in the least.
The resulting 34mm HYPERLITE chassis, with direct mount fender design, plays a major role in the fork’s featherlike weight. The featherweight crown benefits from deep hollow boring to remove excess material from the inside as external machining does the same outside in a manner that strikes the perfect balance between stiffness and weight.
The rear-facing arch and its shorter pathway from leg to leg requires less material and thus represents not only an increase in stiffness but a significant area of weight savings. By using stress analysis software and countless hours in the testing lab, Manitou engineers were able to eliminate excess material from both the rear portion of the arch, the dropouts and other areas thus shaving additional grams from the overall casting weight.
The development of 7000 series straight thin wall legs adds yet another area of weight savings. Further reductions in weight come from material optimization in the production of Manitou’s lightest axle ever produced, te Hexlock SL-R, a R8 specific axle weighing a mere 25 grams.
The weight savings even went as far as optimizing functional internal parts. The incorporation of our lightest air spring, the XC tune Dorado Air, a light weight XC version of the IVA volume adjustment and application specific shaft lengths and materials ensure smooth performance at a lower weight. The newly developed, XC-specific VTT Pro-X sealed damper further reduces weight Only through such thorough and complete actions could a rigid, reactive, and reliable fork with its performance characteristics tip the scales at an amazingly low 1480gr.
Creating the next level in reliable, lightweight and extremely performance oriented front suspension required the development of a fork that performed in all situations and could adapt easily to varied terrain and circumstances. The R8 fork is far from a static unit and the Manitou Engineers worked diligently to produce a premium level remote system to ensure the rider’s complete control of the suspension. While there will be a manual knob option available with the R8 it is most probable that the majority of XC riders will prefer the remote solution. The ACE and DEUCE combo is a Manitou made underbar remote lockout that controls fork, shock and dropper posts. The Ace lever controls the dropper post while the Deuce lever controls both the fork and shock. The two levers are stackable and can be built into the configuration that makes the most sense for each individual rider. In other words, the Ace can be built above or below the Deuce and either can be built as a stand-alone lever as well. In an effort to minimize weight the lever uses 3 mm housing and 0.9mm cable however, is compatible also with standard 4mm housing and 1.2mm cable.

VTT Pro Variable Terrain Tune Adjustments3-Position Compression Adjust With Open Mode Adjust. When developing the VTT Pro damper we 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 other position than lock-out you will reach 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 shimstacks (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.
EXPERT AIR
The Manitou Expert Air spring system contain 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.
Chassis
When developing the chassis of any Manitou fork our primary goal is finding the 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 conventional forward arch fork of the equivalent weight. Because of this we are able to use 34 mm stanchions to save weight while keeping stiffness closer to that of a larger stanchion fork with a forward facing arch.
