MX-Tech Gen 2 Triple compression adjuster for Showa:
The MX-Tech Compression Adjusters were designed to improve the feel and usability of the compression adjustment circuit. The design also improves the pressure balance of the system. This creates a more stable and consistent operation.
It features 3 independent adjustments to the following circuits to give the rider better feel, comfort, and tunablity in a wide range of conditions.
LSB:20 Clicks Standard Adjustment is 10 clicks out.This stands for Low Speed Bypass. The Low Speed Bypass, adjusts the amount of fluid pressure that can bypass past the adjustment circuits. It has the effect of delaying the speed at which the MSC (Mid Speed Compression) comes into effect and makes the shocks action more loose and free in both directions.
MSC:20 Clicks Standard adjustment is 12 Clicks out. This stands for Mid-speed Compression. Inspired by and designed around Enzo Racing's (Ross Maeda) system. The Mid Speed Compression regulates a sub valve which reduces or increases the amount of pressure that goes through the stiffer main compression valve. It has a primary effect on chassis pitch and response to large g-loads and higher speed shaft movements.
LSR:10 Clicks Standard Adjustment is 5 Clicks. This stands for Low-Speed Rebound. We used 3 letter acronyms, had we used 4 we would have chose ULSR. Or Ultra low speed rebound. It is reducing the force created by the rod charge, and has a ability to calm the shock in large rolling undulations at corner entry or at times when the chassis is partially unweighted (such as hardpack corner entry), without having to over adjust the shocks primary clevis located on traditional rebound adjusters. This creates a calmer more planted chassis without a sacrifice in the shocks ability to follow the ground while under throttle in low traction.
We recommend the following adjustment procedure: To optimize the adjustments. Start with the LSB. Typically this is the least adjusted circuit, and in many ways has the greatest impact on overall feel. We recommend using it to create the feeling of movement that you are looking for based on your conditions, it is not uncommon to end up with the adjuster at 1-2 clicks out in some MX conditions, and offroad and 2 stroke riders may end up at 15. Either way once the "gross" feel is achieved use the MSC speed adjuster to adjust for the feel in larger faster movements that you are after. You will turn it frequently, and you will see that the majority of your riding adjustments will be done to this circuit after you initially set the LSB.
The LSR is the last adjuster to tune. This effect is somewhat elusive in certain conditions. Until you recognize the symptoms and response I recommend you wait until you are riding a slick hard surface with bumps and undulations. Pay attention to the adjusters effect at corner entry and the feel of the bike as you brake or drop off a ledge. Adding LSR will slow the lift and give the rider a calmer feeling bike. Once you notice the effect of tuning this circuit it will become more intuitive. You may be asking yourself why would I not just run it full in? The effect can still limit traction and can increase the shocks tendency to pack up when on the gas over larger rollers. So like all adjusters there is a sweet spot that balances the positive and negative aspects.
