    Thanks for the video! I just changed the seals on my dad's Sachs forks. I didn't take the cartridges out so was curious to see what they looked like inside. I converted my XPLOR 48 to traditional OC forks with adjustable base valves, new mid valves, and removing the holes in the compression side cartridge body. It's definitely better now. Might be a little more difficult to do this mod on the Sach forks due to the nature of the vent holes on the compression side.

      Race tech's fork valving kit for Sachs zf forks uses a metal ring that blocks the holes on the cartridge tube, new adjustable base valves, and a mid / rebound valve.

    Thanks for a great video! Questions... It appears there is no adjustable bleed on the base valves, is there a fixed bleed? Will the Lainer adjustable base valves work on a non-modified Sachs SFF OC Beta fork? Or do you need to do the full conversion (to convert the top adjusters to rebound)? I'm looking to add some low speed compression support and am otherwise happy with my fork so I thought adding the adjusters might be a good step?

    • @StepstoPodium
      @StepstoPodium  3 ปีที่แล้ว +1

      Oooh ok! You are right, there is only one mid-speed valve, so less oil being used for damping, but it's no problem as long as you don't start having cavitation. These forks will for sure not be ideal for motocross, for example, but as long as you don't have cavitation, there's no problem in having just one fork leg for compression. This design is quite nice for manufacturers because it's cheaper to manufacture, but obviously is not as flexible in terms of use as a traditional open cartridge fork.

    Having ZF forks on my bike I was eager for the video to release, and this was well worth my wait. Thank you for the excellent video Luis. Now this raises the following question, are standard forks (having both compression and rebound in each leg) are actually harder to keep in tune?

      ​@@StepstoPodium Harder in the sense that all components in a standard fork set are duplicate, both forks need to be setup identically to work in perfect unison. My unprofessional view, I might be way off

    • @StepstoPodium
      @StepstoPodium  3 ปีที่แล้ว +1

      Oh ok! Yes, indeed you have double the work to tune a suspension, but a good practice is that both legs are always the same, no matter what. It gives more work, but on the other hand, if one of the legs looses damping, you have the other one that can still provide it (as opposed to the SFF). It's aaaaalways a compromise in the suspension world 😅😂

    • @StepstoPodium
      @StepstoPodium  3 ปีที่แล้ว +1

      On the rebound leg, don't need to mess with it. About the compression side, do you ride with much weight or are you little over the weight range? Those would be the only times I would mess with the preload adjuster 💪

Do these ZF Sachs SFF have less sag than other forks? At 300mm total travel I would expect 25% sag, ie 75mm. At my weight charts show I need much higher spring rate but that will result in less fork race sag.

      Sim, tens apenas que rodar para a esquerda (desapertar) o ajuste do lado que tem o ajuste de pré-carga, cerca de 10 clicks (se tiveres10 clicks para desapertar do modo que está). Isso já terá um grande impacto na compressão. Se isso não resolver, poderás ter que ver se não há algo de errado. Uma revisão não seria má ideia!

    I believe it's a similar design as WP Xplor 48 open cartridge forks. One of the down side aside from the adjustability is that the cavitation is more severe. So it's only good for slow trail riding...

      True indeed! Overall it's similar and it differs on the midspeed valve, which there's a "cone" valve. But yeah, it's a technology that has limitations, but comes with upside! They're incredibally simple in their construction which makes maintenance a lot easier and cheaper :)
