So, you've tried every mountain bike shock under the sun and they just aren't cutting it, why is that? 

Our EBMX / YSS colabertion shock has been tuned specifically for the SurRon Light Bee kinematics by the best in the business "Suspension Syndicate" in Australia 

The fact is, it's all in the oil..... the physical size of a shock and how much oil it holds matters! As soon as things get hot, oil changes viscosity and cavitation occurs, this has a dramatic effect on both compression and rebound. 

The bigger the shock the better the performance, especially if you ride hard for long periods, but quality dampening and spring rates matter too, that's why we went to the people at YSS. With EBMX driving the requirements we believe YSS have developed the best performing shock you can match to your SurRon Light Bee.

Key Product Info: EBMX Custom Rear Linkage and Triangle for Custom Shock Only

Included with all EBMX Custom Shocks purchased.

The EBMX shock is longer than the OEM shock and is not the same size eye to eye. This custom Rear Linkage and Triangle is set up to bring the EBMX shock in line with the travel of the stock shock, while reinforcing the structure of your bike. Works very well with the upgraded EBMX Swing arm, remember to check the table below for spring weight if using the EBMX swing arm as there is more leverage with the longer swingarm.

EBMX Shock Spring Sizing Chart

This table is to be used for determining the correct spring rate for riders using the EBMX rear shock, linkage and triangle. There are two different configurations depending on if you are using the stock swing arm or the EBMX extended Swing arm.

When using the stock swing arm, EBMX shock, EBMX linkage and triangle the rear wheel travel is 205mm.

When using the EBMX extended swing arm with EBMX shock, EBMX linkage and triangle the rear wheel travel is 220mm.


Rider Weight

Suggested Spring Weight (N/mm)

Spring weight suggestions above are based on trail riding not extreme riding or jumping. If you plan to ride trails with large drops or do large jumps, please up size by 1 or 2 spring weights.

You asked and we listened! Order the file here to 3D Print your own EBMX X-9000 Shroud for the SurRon Light Bee. 

A lot of time an effort has been invested into this design, please only use once and do not share. We have kept the price low so this is accessible for everyone. 

If you do not have access to a 3D printer we expect you will be able to buy these from your local EBMX Dealer in the future.

Through testing we have discovered that most SurRon Light Bee frames, in particular the OEM controller mounts, vary slightly depending on level of use and manufacturing tolerances of the frame. Because of this, sometimes there may be slight gaps between the shroud and the frame on your bike. To account for this, we included slots in the shroud to give some adjustment, we have also provided shims (1mm, 2mm and 3mm) to space the upper mount face of the controller from the frame.

The recommended hardware to be used with the controller kit is shown below. Please note that during assembly of the shroud, do not overtighten the screws as it may damage the plastic. We also recommend installing the socket head cap screws with Loctite to prevent loosening.

We have tested and printed on our printer (Bambu Lab X1C) with the following filaments: PLA, PLA-CF and PETG. We recommend printing with supports at a 0.2mm layer height.

Minimum required bed space: 220mm x 220mm. For best finish and minimal support, align the plate with the edge parallel to the X-9000.
