Rockshox Fork Servicing & Upgrades

Rockshox produce a range of forks to suit all disciplines in mountain biking which includes the popular Rockshox Lyric, Pike, Yari, Boxxer and new Zeb. No matter which Rockshox fork you ride, ProFlow Suspension can service them and get them set up so you can get the best performance out on the trails.

Servicing your forks regularly will not only improve the performance of your fork but it will also eliminate wear and tear on parts which are expensive to replace.

Lower Leg Bushing Resize

If the bushings in your fork lowers are tight bushings they will make the fork feel harsh. If bushings are too loose/worn out then the fork will develop play and you'll hear knocking while you're riding. In both of these cases book your fork in for a service with ProFlow Suspension and we can resize your bushings to fit the stanchions better for some slick, stiction free action.

High Performance Lubricants

During your fork service you can request for the ProFlow Suspension Tech to use high performance lubricants in place of the standard oils. High performance lubricants have higher viscosity, last longer and perform better under high pressures and temperatures.

Custom Damper Tuning

A custom damper tune is where we re-valve the suspension damper to suit the rider. Dampers are tuned for the 'average' rider which tends to be 80kg and mediocre ability so this tune won't be very suitable for a rider who for example weighs 55kg and rides hard, or a 100 kg timid rider. Custom tuning benefits people who are small/big wanting more performance. During a custom tune we adjust the shim stack in the damper by changing the number of shims in the stack and the size of the shims. This is done in the mid valve, compression and rebound within damper. Adjusting the shim stack will allow oil to pass through more easily for smaller people and add more resisitance for bigger people. At ProFlow suspension we use the Vorsprung Fractive kit for custom tuning.

Air Shaft Travel Change

An easy and cost effective way to fine tune your fork to your riding style is by changing the air shaft travel. Fox forks are designed to work at a range of different travel options, for example a Rockshox Pike has travel option between 120mm and 160mm.

Volume Spacers

Volume spacers are an easy way to improve the performance of your fork. Adding volume spacers means you can run less air pressure in the fork which makes the beginning of the travel more sensitive helping with small bumps. The middle stroke will be more supple and the end of the stroke will be more progressive and ramp up meaning you're less likely to bottom out the fork and cause internal damage. Volume spacers come in a range of sizes so you can customise your shock depending on what you're trying to achieve - the more spacers the higher resistance to bottom out; smaller spacers will make the travel more linear and allow the rider to use more of the travel effectively. ProFlow can assist you with fork set up to make sure its working how you want it to.

Fork Service


At ProFlow Suspension we strip the fork down to its component parts, inspect the parts for damage, clean everything, test the parts and reassemble the fork with brand new seals, oil, grease and foam rings.

We then test the fork using our CTW Dyno to ensure the forks are working correctly and are not faulty.


  • Full strip-down
  • Close inspection and thorough cleaning of all components
  • Rebuild with new genuine manufacturers seals (unless specified otherwise)
  • Vacuum bleed (some dampers are hand bleed) with high-performance oils
  • Function test with CTW Dyno / leak test
  • Return to pre-service settings
  • Function test with CTW Dyno


EXT ERA Fork: $350
Ohlins Forks: $330


  • Standard service plus 
  • Dyno damper test pre strip down 
  • More in depth testing to examine what the shock is doing at any point in time and match the shock/fork to the bike and rider style. 


Ohlins Forks: $365

Understanding Your

Bike Fork

Air Springs

Air springs are more common in most modern mountain bike forks than coil springs. The air spring is set up to resist the weight of the rider so the heavier your are and the more aggressively you ride the more air you will need. Smaller more timid riders need less air. This is easily adjustable with a shock pump and can be adjusted in small increments to custom tune the fork to the rider. With a coil fork you need to change the spring, you can buy a range of spring weights which will be recommended for riders weight by the product manufacturer. If you're unsure if your forks are set up correctly then feel free to get in touch and we can take a look.


Dampers control the motion of the fork and make it feel less like a pogo stick and smoothing out all the bumps in the trail. Getting the damper set up properly will increase front wheel traction while riding rough trails and while cornering. The damper in your fork is filled with hydraulic fluid, the movement of this fluid is controlled by the compression, rebound and lockout dials on your fork which open/close various ports. For example the lock out dial simply closes all of the damper ports, stopping oil from flowing and therefore stopping the fork from moving. ​ Your damper is filled with hydraulic fluid and the lockout, compression, and rebound controls are actuated by opening and closing various ports through which that fluid flows. For example, when you lock out your fork, you’re simply closing all of the damper’s ports, which keeps the oil from flowing.


It's important to get the rebound of your fork set up correctly because if it's too slow, your fork won't have rebounded fully before the next impact which makes your fork feel hard and will send impact through your hands. Too much rebound and you'll bounce off every root or rock you come across breaking traction and feeling sketchy.


The upper part of your fork is made up of the stanchions (legs which slide into the fork lowers), crown (connects stanchions to steerer) and steerer tube (connects the fork to your bike). This is known as the CSU (crown steerer unit).


Fork lowers connect the fork to your wheel and slide upwards during compression. Lowers house the bushings and lubricating oil, which make contact with your uppers. They also house the wiper seals which keep dirt out and the foam rings which provide lubricating oil to the seals and bushings.
