Watchful eyes might have noticed the chassis of the Manitou R8 on the World Cup bikes of the pros in recent months. We have all the facts about the new, cross-country-specific fork, and we've already let it loose on the trails. There's also a new Mara IL damper generation.08.07.24 07:51 626

Olympic years are generally good years for product launches that affect the XC sector. Manitou now entered the stage with a successor to the R7. Lighter, stiffer, and featuring a practical remote lever, the new R8 offers 80-120 mm of travel.

Looking at the World Cup tracks of recent years, it becomes clear: suspension forks have to endure quite a lot. And it's not just at the highest level of racing that many things have changed. Subcategories of Cross-Country have established themselves, the travel of light racers has generally increased, the bikes as a whole have become much more capable, also in conveying confidence on technically demanding trails.
The R8 aims to cover this entire spectrum and thus achieve a balance of low weight, high stiffness, and above all, versatility.
To achieve this, continuous feedback was sought from the fastest World Cup racers in the world. And indeed, the fork has already been rewarded with World Cup podium placements by the American Savilia Blunk (Decathlon Ford Racing Team).

The Numbers

Compared to the R7, the stanchions have been increased to 34 mm for increased stiffness in the R8. Manitou calls this chassis the 34 mm Hyperlite, including a direct mount for a fender.

The design of the stanchions is coupled with Manitou's already known Reverse Arch, which - mounted on the back of the fork - covers a shorter distance between the stanchions. This allows the weight to be pushed down and the stiffness to be twisted up.
The brake arch has been further optimized using stress analysis software and overtime in the testing lab. Material was reduced on the arch itself, as well as on the dropouts (44 mm offset) and the stanchions where possible. The chassis is made of 7000 series aluminum.

The fork crown features a deep hollow bore to remove excess material from the inside. External machining achieves a similar effect on the outside.

The 15 x 110 mm Hexlock SL-R axle is the lightest version that Manitou has ever produced. It weighs only 25 g.
All together this leads to a low total weight of 1,498 g measured with full steerer tube length.

Air suspension

The Dorado air suspension received an XC Tune and includes a balance valve, which automatically levels the positive and negative air chambers during filling. This is intended to ensure consistent suspension behavior without dead spots throughout the entire travel, regardless of rider weight.

On the backside of the stanchions below the brake bridge, there are small screws through which accumulated air can be balanced. This feature - normally found only on suspension forks with longer travel - has been named TSR (Trail Side Relief).

If the spring characteristic curve seems too linear, one can replace the Top Cap with an IVA XC (Incremental Volume Adjust) Top Cap, which can reduce the volume of the air chamber in several stages, thereby mainly increasing the end progression.

Damping

While most shocks use a single piston or damping circuit and riders must either live with a harder lockout with less sensitivity or vice versa, Manitou has sought a solution to this problem.
The R8 integrates the patented VTT PRO-X, a triple piston-controlled VTT system (Variable Terrain Tune), which is controlled via a lever or a remote on the upper stanchion.

Position 1 mainly regulates the low-speed compression damping and offers the highest sensitivity for long and rough descents, where control and riding comfort must be balanced. Position 2 enhances both low- and high-speed damping to improve support during aggressive riding styles. Position 3 is a firm lockout, controlled by a separate piston.

In detail, the VTT PRO-X setup offers a precisely tuned low-speed compression damping setting in Position 1, allowing for the most unrestricted oil flow for high comfort.
To avoid compromises in high-speed compression damping, VTT Position 2 activates another piston, adding both high- and low-speed compression to increase suspension support; this is also achieved by keeping the fork higher in its travel, thus better prepared for larger hits. At the same time, a harsh damping characteristic is avoided because, unlike some XC competitors, it doesn't rely solely on low-speed compression damping for control.
With the full lockout as the third option, Manitou's technology creates three separately activatable circuits, each smarter in handling different riding scenarios.

The rebound damping is adjustable in 18 stages over a wide range at the lower fork tube.
The entire shock is based on a closed bladder system.

Travel

The travel range is adjustable between 80 and 120 mm in 10 mm increments using internal spacers. The travel spacers interact with the volume change in the negative air chamber, which is why the responsiveness of an 80 mm travel setting should feel similar to that of a 120 mm setup.
All necessary parts for the adjustment are included in the delivery.

The R8 is equipped with a Postmount 160 mount for disc brakes, with the maximum possible disc size being 203 mm. The fork is approved for loads in the ASTM category 3. The maximum tire width for the 29" fork is 62 mm.

Remote Control: Ace/Deuce

Although there is a manual adjustment lever, Manitou assumes that most XC pilots would prefer to use a handlebar remote to adjust the VTT function. Accordingly, they have developed two combinable remotes to operate the fork, shock, and telescopic seat posts.
The Deuce lever can control the three positions of the VTT damping of the fork and at the same time also the shock. The Ace lever for operating telescopic posts can be added and can be stacked above the Deuce lever.

Mara Pro IL Gen 2

In keeping with the concept of the R8, the Mara Pro Inline rear shock has been revised. The new design includes grid steps for precise rebound adjustment and also incorporates a new IPA shaft (Incremental Platform Adjust) for improved lockout performance.
Available with a stroke of 30 to 65 mm, the component is usable for a wide range of different bikes.

Additionally, a dedicated XC version of the shock featuring a smaller Lite Can air chamber, reduced weight, and a stroke between 37.5 and 45 mm has been launched. A highlight is a special shim stack for damping, guaranteeing the strongest lockout performance.
The XC version with Lite Can weighs only 294 g, while the version with King Can should have a few grams more. Both options are available either with control levers, or prepared for a remote.

Riding Impressions of the R8

You don't have to roll around with the Manitou R8 for long to predict that the new platform could significantly shake up the cross-country market.
Our test model was delivered with 120 mm of travel and installed in a Merida One-Twenty with the same rear travel.

The development team has done an excellent job tuning the VTT system. The recommended air pressure seems to fit the respective rider's weight very well right from the start, and the corresponding rebound setting is also quickly found.

As is often known from Manitou, they have also managed with the R8 to combine stiffness with low weight. For an XC model, the R8 holds its line quite precisely and doesn't feel like a noodle in berms.

In position 1 of the VTT setting, the fork responds extremely sensitively to uneven surfaces, but also handles larger bumps really well and provides a comfortable setup.
It is astonishing how efficiently, controlled, and harmoniously the 120 mm travel works. The fork generally feels in most situations as if it has more travel to offer.

Position 2 of the VTT setting is not only suitable for climbing thanks to the increased low-speed compression. Due to the increased high-speed compression, it is especially advantageous for a more aggressive riding style in downhill.
This is not just marketing talk, but clearly noticeable on the trail when you really pick up speed – in a positive way, without feeling harsh.

The basic tuning of the fork is so well done that you quickly forget you only have 120 mm of travel available. This even encourages you to engage in maneuvers that can push the geometry, a moderately tuned rear suspension, or in the case of a hardtail, the non-existent rear suspension to the limit. A problem you gladly accept.
And when you look at the increasingly challenging international race tracks, it conveys that it's okay to venture onto trails with the R8 that you wouldn't explicitly attribute to the cross-country genre.

It's not impossible to bottom out the R8 in position 2 with harder gear and the occasional medium-sized drop. If this happens too often, the IVA Volume Adjuster allows for multi-stage adjustments to ensure more end progression of the air spring and thus increased bottom-out protection.

 One can only marvel at how efficiently, controlled, and harmoniously the 120 mm of travel work

Position 3 with its lockout function seems to be really stiff. However, I didn't spend much time in this mode, because when climbing, the mix of sensitivity and efficiency of the VTT Position 2 is too well-tuned.
By the way, operating the different VTT functions using the Deuce lever works quickly and smoothly, allowing you to easily and frequently switch between the different modes depending on the trail conditions.

Overall, the new Manitou R8 leaves a very strong impression. It will have to prove its durability in the coming months and years. Whether on the most demanding World Cup tracks in the world or on the beloved evening ride at home, even if it turns out to be slightly more technical, this should hardly matter.
