Does anyone use this stand or one of the other similar models?

I bought mine from craigslist only to find that I cannot lock the arm into place, so I cannot rotate the bike and keep it in that position. It has a handle at the back of the arm that I believe you should be able to flip to lock the arm in place but mine flips freely back and forth but does not lock into place.

Anyone had any experience with this problem?

Thanks.

contract parktools .com , they have a great service dept . they will repair or replace the part at little or no cost to you . I have deal with them over the years and always been there when I needed them . Good luck .

Flipping the handle back and forth does nothing. Righty tighty, lefty loosey.

Turn the handle.

20:1 you're missing the conic bushing between the clamp assembly and base unit. Go to the Park site, find the parts list for your stand, and you'll see the part, you need.

We have these stands in the coop- the handle flips for nothing other than ergonomics. Righty tighty indeed.

Edit: just processed what FB posted. FB knows what's up. Still, try twisting it first.

FB, great suggestion.

So, I checked the site and they do have a two page illustration for instruction as well as a parts list.

I wasn't able to find anything listed as the 'conic bushing' but there is a cone shaped piece (#7), which must be it? I actually do have this piece. In fact, from the illustration I don't think I'm missing anything.

Part # 9 is there but I was unable to pull it out to inspect it, but I couldn't imagine that would make a difference?

When I tighten it (righty-tighty) it eventually gets to a point where it is so tight that I cannot turn it anymore, however the bike can still freely spin. It's as if there should be some kind of heavy rubber grommet between #9 and #11, instead of simply a washer.

There is an ever-so-slight bend in the threaded rod. Do you think this could possibly be the problem?

Any other thoughts or suggestions?

Call them?

Step 1, you have the stand, and you have a picture that shows all the parts. So disassemble the stand and check that it's complete.

Actually, in this case I was off. The older better versions like PCS-1 and others used a replaceable wearing cone between the clamp and mounting tube. Looking at the exploded view, it seems that Park decided to save a buck or so by skipping it.

This arm functions similarly to a QR-skewer on the wheels. It has a lever that pulls on the rod AND a rotating adjustment.

1. First, find the direction the lever moves to loosen and tighten the clamp.
2. place the clamp-lever in the OPEN position so that the clamp's jaws are wider
3. tighten the clamp handle assembly and you should see the clamp's jaws slowly close
4. flip the clamp-lever into the CLOSE position and this should be the final movement that holds the frame.

Go back to #2 and repeat #3 as needed so the clamp holds the bike in place. Personally, I like to position my bike so that it's balanced in the jaws of the clamp and doesn't need to be clamped too tightly.

Danno, you're making a similar mistake to mine and thinking of earlier versions. The lever on this isn't a cam at all but simply a simple wing nut (of sorts). It's similar to the levers Park uses elsewhere in the line offering a built in wrench that flips 180° for convenience.

Oh, thanks for the clarification. Looks like this is a step backwards and we're supposed to use it like wing-nuts instead of QR skewers.

I have one if you can't figure it out...

This is what I did, essentially. I took apart the top but left the stand intact. The only thing I couldn't take apart was the piece that sticks into the back of the tube, but I dont' see why that would matter.

Exactly right.

So Wallbrown, you just keep screwing it tight until the bike won't move? Is yours hard to tighten? Does it hold the bike, stiffly, in any position?

So, I'm feeling pretty darn silly. The short-of-it is that you can tighten the clamp so that it will not rotate and you simply do it by screwing the handle around. I was trying to do it quickly, without putting my bike on the stand. I just needed the extra weight of the bike to hold the clamp in place ... I wasn't able to hold the clamp in place while I was testing it.

Anyway, it works. Thanks to all for suggestions.

Yes. No. Yes.
