Looking at entry level SR SunTour suspension forks, there are the options of

  • "MLO" - mechanical lockout
  • "HLO" - hydraulic lockout
  • "RL" - remote lockout

Now, mechanical and hydraulic lockout is clear. Remote lockout - not so much - it says that it is engaged from the handlebars, not from the fork itself.

My forks says XCR 011 Series mg. On the side of the knob is written "Speed lockout". I am able to lock the fork while compressed, but if I do it uncompressed, there is some small damping still, which is very nice.

How do I know what is this "Speed lockout" thing, without disassembling the fork.

Note that I have been unable to identify the exact model of the fork.

  • hey does anybody know if a hydraulic lockout can be used with a remote? like if a bicycle has an option of remote lockout. does that mean the remote has been added to mechanical or hydraulic lockout? its confusing as the remote lockout itself is not a type of lockout but just a remote added to an existing lockout technology like hydraulic or mechanical. but which one of the two is it is what i wanna know

Remote lockout means that the fork has a "remote" lever that is installed in the handlebar.

My fork is a XCR RL from 2011 as well and pressing the blue lever locks the fork, pressing the black lever on top of the blue unlocks it. This is a XCR from 2011 as well.

You can see the remote in the following picture:


If you have a knob with speed lockout you should have a fork similar to SF11 XCR LO 26". If your fork has rebound adjustment then it's a XCR LOD. You'll have to look that up in Suntour's site since I can't post more than one link.

Browsing Suntour's Tuning Base may give you additional information.

  • Yea, it looks very much like the SF11 XCR LO 26". On the SunTour site it is listed as "Hydraulic Speed lock". Does this mean that my lockout is hydraulic for sure?

  • Reading the SRSuntour service manuals, they say "every SunTour fork will retain some travel after being lock-out". Also "the patented blowout system is intended to disengage the lockout when a hard enough hit is received (forgetting the fork locked and going downhill.)". Note that those are not exact quotes.

  • If the lockout knob is blue, then the lockout must bi hydraulic. But i'm not 100 percent sure about it.
