    Depends on your weight. My new (to me) Lefty Max PBR... I thought the damper was broken, but the lockout worked just fine. Turns out somebody put some mega thin damper oil in there. I changed it out with some 5wt Motul motorcycle fork oil, and now it feels great. I think I could even go 7.5wt. I'm 210 pounds, and like a fast fork (but it was way too fast when I got it). I tend to lean towards the quick rebound side of things, but not so much I bounce off the trail into the bushes after landing a small jump.

    OK, so I have a large 2013 F29 with the PBR fork that I bought new and haven't had apart. I recently noticed that my stem spacers were slightly loose and there was a creak in the stem, so I removed the steerer assembly. Inside on the end of the steerer were three black spacers and a red spacer with a beveled edge.

    Are all four of those spacers supposed to be there? I looked at schematics and don't see them. I put the bike back together and tightened everything up to spec and there is still a little looseness to the stem spacers, which I think is due to those other spacers on the steerer. Is it safe to remove one or two of those internal spacers (which I suspect would allow me to get my stem nice and tight)?

    Thanks!

    You have the MK2 (revised and supposed better) version of the steerer, the inside spacers must match the number of the outside spacers (the red inside one is mandatory, doesn't count). Take a look here for the schematics and additional info : V2 OPI Steerer

    Wow, thanks. I didn't know that (and I appreciate the heads-up!)

    Hi Everyone

    just a quick question I have just replaced my the top collar (part no kh 101) on my lefty and I have noticed that there are three orings that are to be fitted into the collar. there are two large orings and one smaller one I have managed to work out that the smaller of the three orings fits into the recess at the top of the collar (will be located between the rebound adjuster and the top caller) but I am not sure where the two larger orings go. I would be very grateful if anyone could advise me where the two large orings go.

    The official Lefty thread, tech, mechanical, etc

    Arghhhh - is there a secret to threading in the steerer tube from under the headset into the OPI stem on a Lefty F-29. I can't get the male threads in the steerer to make purchase with the female end of the stem. If I pull the stem off, I'm looking down the the head tube at the top of the steerer tube, so it seems like should thread right up. Any help appreciated.

    Ok - got it. Apparently the trick is to lube the OD of the base of the OPI stem so that it slips through the upper headset bearing far enough to grab the male threads on the steerer.

    Quick question: What's a good estimate for the Axle to Crown measurement on a 2013 XLR 100mm 29er Lefty?

The travel reduction spacer is about 0.5mm larger in diameter than the upper air seal and you need to file it down or it won't go down the lower leg. It's a one minute job. Besides this it went as smooth as expected, though the locktite on the damper was very hard to break free. You need a lot of force to get it loose and be very carefull that the castle tool doesn't slip out of the damper interface or you will be in trouble. My fork was originally 490mm A-C now it's 480mm and you can definitely feel the different in steering, but I don't notice any change in suspension feel at least on tarmac.

    EDIT!

    I just realized that placing the spacer in the position indicated above will cause the spacer to move on the damper shaft when the fork is compressing which might cause wear on the surface in the long run. I have revised the placement to now be between the lower bottom out bumper and the lower air seal. The spacer should not move when place in this position.


    it's crazy how people manage to mess up everything with the only justification to DIY ... that clip in spacer is only used under the top cap, in the position showed in the picture will cause the malfunction of the soloair system...
