Ohlins RXF 36 M.2 29″, 160mm, 44mm offset.
The RXF features Low and High speed compression, rebound, air preload and ramp chamber.
Air Spring & Ramp Up Chamber
The Ohlins RXF 36 M.2 TTX18 allows riders to fine tune performance via the “The retuned, twin piston, three chamber air-spring system allows you to completely dial-in the level of progression – from the initial movement, right through to the bottom out. The air spring is cartridge based, so you can easily change between coil and air spring cartridges if desired.”
Ohlins’ suggested baseline for the RXF 36 is below varying from 70-140 psi in the main chamber and 160-230 psi in the Ramp Up Chamber (which modifies ramp rate).
You can learn more about the Ramp Up Chamber concept by reviewing the Volume Spacers video tab below.
Ohlins RXF 36 M.2 Rebound Control
The Ohlins RXF rebound is tuned by the gold adjuster on the bottom of the air spring fork leg.
Turning clockwise you increase the damping, slowing the fork’s return to neutral while turning the gold knob counter-clockwise decreases damping, or speeds the fork’s return to neutral.
Learn more about rebound control in the tab below with a video and writeup explaining Rebound and how it’s setup is tied to air pressure, ramp rate and compression.
Ohlins RXF 36 M.2 TTX Compression Controls
The Ohlins RXF fork features tool-less high and low speed compression adjustment.
Low speed compression helps provide support in fast corners and steep or burly terrain. Fine tuning the low speed compression allows riders to manipulate air pressure for the best balance of small bump compliance and bottom out resistance.
High speed compression provides support more associated with fast shaft inputs or climbing, etc. In fact, the Position 0 (zero) is suggested only for long climbs as it’s additional support may compromise traction downhill.

Ohlins TTX Air Rear Shock
Air Spring & Volume Spacers
The Mondraker Foxy Carbon XR uses an Ohlins TTX Air 205x65mm shock.
25% sag is set at a 16.25mm or a bit more plush is 30% at 19.5mm.
Volume spacing provides fine tuning options to support the air spring.
Larger volume spacers, thus reducing the volume, increase the air spring’s ramp rate for improved bottom out support and pop.
Conversely smaller volume spacers produce a more linear feel as the air has more volume during shock compression per mm of travel.
Ohlins TTX air shocks can install one (x1) volume spacer only.
Ohlins TTX Air Shock Rebound Controls
The Ohlins TTX rebound is adjusted with a 3mm allen wrench on the gold controller. Like the compression control the Ohlins TTX rebound control has a distinct stop on both ends of adjustment. Don’t force the adjusters past the stops, oil leakage or damage to the shock may occur.
Ohlins TTX Air Shock Compression Controls
The Ohlins TTX Air Shock features a 3 position High Speed Compression, including the “P” pedaling platform. Position 1 is soft and position 2 is medium. This is controlled with the black 3 position lever.
Opposite of the High Speed Compression lever is a blue cylinder head with an allen adjuster to control low speed compression.
Low speed compression is used to provide cornering support as well adding support to assist the initial air spring stroke.
You can learn more about suspension setups in the tabs below with videos and writeups covering Air Spring, Volme Spacers, Compression and Rebound.
Learn about suspension setup basics on the following tabs. Each tab has a video with the basics of Air Spring / PSI, Volume Spacers, Compression, Rebound (or watch it all in one place with the final tab).
Each tab has a text section with a bit more in-depth look at the typical MTB suspension settings and how they intertwine.
PSI / Spring Rate
MTB suspension must accommodate a wide range of rider weight. To achieve this nearly all forks and rear shocks use an adjustable air spring.
By varying air pressure riders set a desired sag, or percentage of travel that the bike “sits into” under neutral loading.
Modifying this sag percentage will change small bump compliance as well as bottom out characteristics.
Learning how to Pre-Charge your suspension pump will help you make finite adjustments to sag.
Typically 15% sag is for a firm setup and 20% sag is considered plush.
Air Spring Fine Tuning Control(s): Volume Spacers & Compression
Air springs ramp rate, sometimes called Spring Rate, is based on how air compresses in the containment cylinder. As the air is compressed the PSI increases according to the decreasing volume of the containment. This is done via non-compressible volume spacers in the air chamber.
Hydraulic damping assists air spring providing support in mid-stroke and bottom out.
Opposing Control: Rebound.
Higher spring rate will drive the suspension back to neutral with more force than a lower spring rate. To keep the bike from skipping across trail rebound damping is utilized.
As suspension compresses (travel reduces) a piston moves closer to the end of a sealed container. By decreasing the volume of the container the PSI pushing back on the piston is increased.
By adding or removing non-compressible volume spacers riders modify the air spring’s ramp rate which directly changes the amount of support and bottom out feel of the fork or shock.
By removing volume spacers a rider increases the available volume in the suspension. The larger volume compresses less per mm of travel resulting in a lower PSI per mm of travel. This creates less support and is utilizes more travel.
Adding volume spacers decreases the available volume. With less air volume the PSI per mm of travel increases providing more support and greater resistance to bottom out.
Opposing Control: Rebound.
Rebound may need to be adjusted for volume tuning depending on how drastic of a PSI change is being tuned in or out of the suspension.
“Helping” Control: Compression.
Compression provides additional support and bottom out resistance.
Compression controls provide damping to slow suspension travel as a load is applied and the suspension is compressed. (easy one right?)
When riders have found sag and volume spacing preferences compression controls provide minute adjustments to dial in performance. Adding compression provides more support allowing the suspension to ride taller in its travel which is important when dialing in a bike’s personality in corners, etc.
With too little compression a bike will sit deep in the travel. This compromises cornering and braking force resistance. Headtube angle, bottom bracket height, front to rear weight bias, etc are modified as a bike goes through its travel. Maintaining control of the use of travel is paramount for good performance.
Since compression hydraulically slows the suspension’s use of travel it therefor lowers the air spring’s PSI. Properly setting compression controls will help ease the load on the rebound system by controlling the air spring’s push back onto the rebound circuit.
Too much compression will cause a bike to feel harsh and not use appropriate amounts of travel.
Generally, compression settings are fine tuned after sag and volume spacing have riders “in the ballpark.”
Low speed compression controls mid-stroke as well as support in cornering and against brake dive.
High speed compression helps with bottom out and high shaft speed inputs.
3 positions switches are a type of compression circuit with Open the most plush, Mid providing some additional support and Firm for climbing. If you climb in firm remember to put it back to plush for the downhill or you’re in for a potentially rough ride.
Rebound damping controls a suspension’s shaft speed returning to a neutral position. Or, how fast the air spring pushes back as the load changes.
More rebound damping slows the suspension by decreasing the amount of fluid allowed to pass through the hydraulic design.
Less rebound damping allows the suspension to return faster with less hydraulic restriction on the damper.
Rebound setting is based on weight, ground speed, terrain and aggression. Setting the rebound properly means finding the right frequency or feel for your riding.
If your rebound is too fast, or doesn’t have enough clicks of rebound, the bike will tend to skip and suffer poor small bump compliance.
When the rebound is too slow, or you have too many clicks of rebound, the suspension may “pack up” creating a harsh ride as each bump uses progressively more travel forcing the suspension deeper into the travel, which will have higher spring rates.
Opposing: Air Spring PSI / Spring Rate.
“Helping” Control: Low & High Speed Rebound.
Some suspension is designed with 2 rebound circuits. The High Speed Rebound circuit is designed to provide additional control resisting increased PSI late in suspension travel.
Typically High Speed Rebound settings are used as the Low Speed Rebound controls edge towards closed. Example: you might not use any clicks of High Speed Rebound until you reach “X” clicks on the low speed.
Mondraker Zero Suspension Design
Mondraker’s Zero Suspension is designed to isolate the suspension from chain growth and brake jack. By eliminating these influences to the suspension design the Mondraker’s have Zero concerns beyond the rear shock dialing in the performance.
Unlike many other MTB brands which mount the shock to linkage and the front triangle, Zero Suspension arranges the shock mounts on the suspension’s upper and lower link.
This mounting configuration allows the suspension designer a handful of advantages.
Notably the lower pivot is able to be located around the chain ring’s 12 o’clock quadrant, thus helping minimize any chain growth or pedal feedback.
Designers are also able to better control the angle of input from the linkage lever to the air shock. This is what creates the shocks performance based on how the link versus shock angle is designed.
The image above shows an example of rising and then falling rate suspension design.
Designing a suspension to utilize the input angles produces linkage that compensates for air ramp rate as well as helps maximize small bump compliance by working near to a 90 degree, or cosine 1.0 input factor.
The better designed the suspension linkage system works closer with the predictable air pressure changes and requires less damping accommodations which can create other issues depending on riding style, ground speed, terrain, etc.
In short: well designed suspension like the Mondraker Zero allows shocks to work better and each click of rebound or compression a more precise, less knife edge setup.
From Mondraker’s Site:
Mondraker ZERO Advantages
• Zero power loss. High pedalling efficiency. The power applied to pedals is transformed to immediate forward motion without any extra compression or extension of the rear shock.
• Zero pedal kickback Chain length growth throughout the suspension travel is minimum, so pedalling is as effective and efficient as possible.
• Zero brake jack Rear brake forces do not work against suspension forces. The rear shock works supple and freely and absorb impacts without any suspension stiffening caused for the rear brake action.
• Zero bumps The most remarkable feature of the system is its excellent suppleness on rough terrain and a completely stable ride when pedalling.
You can find Mondraker’s exclusive and patented Zero Suspension System on all Mondraker full suspension mountain bike range.

Popular Upgrades to the Mondraker FOXY Carbon RR
There are a variety of popular upgrades or part swaps on the Mondraker complete bikes. Flip through the tabs below to explore some of the most popular including Brakes, Tires, Chain Guides and Frame Protection.
Along with tires the most common upgrade or swap to a stock Mondraker build is brakes.
Brakes are extremely important to your bike’s personality as well as your confidence on trail.
Finding brakes with the right modulation and power for your riding style allows you to further fine tune performance with rotor size.
Brake modulation is how the lever position relates to the amount of power at the caliper.
Brands like Magura and Hope offer great modulation. A slight pull on the lever will produce less pressure at the caliper and increases as lever throw continues. Magura riders can fine tune this even further with a variety of short or long brake levers to further modify the leverage ratio. In fact, Magura offers brake levers with adjustable modulation!
Shimano brakes have less modulation and the power tends to “come on” quicker. This isn’t necessarily good or bad – it’s just a personality.
Magura and Shimano offer similar levels of total power differing in personality more on modulation than max power or feel.
Hope brakes have a little less “bite” at full power but most riders are able to fine tune this by running a slightly larger rotor to increase both leverage and heat capacity.
Pricing / Value
Interested in updating the brakes but on a tight budget? Check out the Magura MT5. In many cases it’s available as a No-Cost upgrade. Cost conscious yes, light on performance or service life? Not a chance. The MT5 brake is the most popular offering here at BikeCo.com
FOXY Carbon RR Tire Upgrades / Swaps
The Mondraker FOXY Carbon RR kits are spec’d with Maxxis Minion DHF 3C Maxterra, EXO+ with 120tpi, 29×2.5″ front tires. The rear tire is spec’d with a Maxxis Minion DHR II 2.4 3C MaxTerra EXO+ with 120tpi.
Since tires play such a big role in a bike’s personality it’s very common for clients to swap to other tread patterns, sidewalls or sizes.
Some of the most popular changes are listed below.
Front Tire: Spec’d Maxxis Minion DHF
The Minion DHF has been an enduro favorite for years. In fact, well before enduro had become the accepted name for the riding style.
The Minion DHF features a relatively fast rolling center, with sipes in the center lugs to provide additional grip in cornering.
Cornering knobs on the Minion DHF are relatively stiff for support including the unique lateral addition to provide additional leverage against over-riding the cornering knobs.
Riders looking for a more aggressive front tire should check out the Maxxis Assegai for little more front end bite.
Rear Tire: Spec’d Maxxis Minion DHR II
The popular Minion DHR II rear tire provides balanced performance with the Minion DHF front tire. The DHR II features siping for improved braking on the center lugs with similarly robust cornering knobs to the DHF front option.
Riders looking for a more aggressive rear tire should shop the Assegai while those looking for something slightly faster rolling may go to the DHF or Aggressors.
The EXO+ stock tires are a popular option balancing sidewall support capable of attacking burly terrain without adding too much rolling weight.
EXO+ construction combines two puncture protection materials: SilkShield and EXO. The SilkShield layer runs from bead-to-bead with a layer of EXO along the sidewalls. Combined, these two materials create EXO+ which improves tread puncture protection by 27%; sidewall durability by 51%; and resistance to pinch flats by 28%.
Riders looking for additional sidewall support and resistance to damage will shop the Double Down or DD options
DoubleDown (DD) is the next step in the evolution of the dual-ply tire casing for enduro racing. Two 120 TPI casing layers reinforced with a butyl insert provide the enduro racer with the support and protection of a downhill tire, but in a lighter package.
The “light” tire option for most enduro riders would be the EXO sidewall.
An extremely cut-resistant and abrasion-resistant material added to the sidewalls of select mountain tires. This densely woven fabric is also lightweight and highly flexible, ensuring that the performance of the tire remains unaffected. Choose EXO Protection for exceptionally rocky, treacherous trails where the chance of sidewall cuts and abrasions is high.
One of the most common upgrades to the Mondraker lineup is adding a chain guide.
A variety of options are available depending on your riding needs.
The Wolf Tooth Gnarwolf is a great upper guide as is the OneUp option.
OneUp goes a step further with the Guide + Bash or, for riders who don’t need or want the upper guide, simply a lower bash to protect the chain ring and bottom bracket area.
The lower bash only is a popular option with oval chain ring setups that can be complex to pair with upper guides.
RideWrap Frame Protection
A popular upgrade for any mountain bike, we offer two options of RideWrap Frame protection.
The RideWrap Tailored Kit covers the majority of your frame based on individual model size and shape. This is a $95.00 addition. We will install the Tailored kit for an additional $250.00 labor at time of initial build.
RideWrap’s Covered Kit protects the high wear areas such as downtube, top tube, etc. Custom trimming of the stock Covered Kit helps with fitment depending on model and size. The Covered Kit is $65.00 and installation is $150.00 at time of build.
Installing RideWrap isn’t particularly hard – but it is time consuming. Thinking about doing the labor yourself? Awesome! Check out a quick video on the installation process below.
