    The XLR 120mm stats are: - 120 or 130 mm of plush travel

    - Weight: 1320 Gramm(120mm)-1315 Gramm (130mm)

    - forklength: 49cm(120) -50cm(130)


    whilst the XLR 100: - 100 mm of plush travel

    - 1394 Gramm

    - forklength: 47cm


    The difference between forklength is a few centimeters I think its important to get a specialist to discuss if it is worth doing as your geometry will change and if you truly race it may not be astute (not my field). What I do know is that you can use the spacer clips to ensure it doesnt hit the post:

    I am sure someone will come up who has changed their forks.

    Thank you very much for your answer.
    The reason I think about the 120 is that in the future I will be able to use it in just 29 bike with 90 mm travel.

    CB "No that's a terrible idea, we'd sell like six"

    ME "You're discounting Canadians, they love those!"

    CB "Please just go buy a Trek..."

    actual conversation that would happen

    I've reset the bearings on my Lefty a few times and the problem keeps recurring within the first ride.
    It feels like there's no damping for the top 20mm or so of travel.

    I went a bit further today and stripped the fork almost completely and this is what I found.



    The three white spacers at the top are travel reducers as it's the 29er version.
    Immediately below them is a small black spacer.

    Below that is a white plastic cap that screws in to the top of the long red tube.
    That cap was loose, completely unscrewed, when I stripped it.

    You can see the bottom white cap off as well. I unscrewed that one.

    There was a bit of oil everywhere, I take it the red tube should be a sealed unit with the two white caps keeping the oil in ?

    So, the question now is, how much, and what type of oil, do I put in there ?
    Is it two separate chambers, or are they linked ?
    Fill it up, or leave a 10mm air space ? Or is there a specified volume ?

    One other thing that I noticed is that the long flat steel tracks that the needle rollers run on are slightly curved.
    Does that matter ? I can't see it being a problem once everything is in place.

    Hi, I've got a 2012 Flash Alloy 29er, with a 90mm travel PBR Lefty. I would like to liberate another half inch or more travel as some of the trails I ride can get pretty rough and there are some nice rollers that you can get easy air off and decent rock gardens, so feel I could do with a bit more travel on the Lefty. My question is, is it possible to get some more travel out of the fork, and if so how much and what do I need to do it? The fork is probably due for its first full service so now's the time to do it. Thanks.

    hi,
    i've got lefty PBR 130 of 2009 model and I just wonder can I make it 140 mm of travel putting in some proper damper and air kit? Or maybe I can do that just swapping for a proper air kit on my current 130 mm damper (KH041)??
    Any idea?
    Thanks.

    My understanding is that there is an air seal that either has to be modified or replaced. MendonCycleSmith is the person to contact.

    I have a Headshok Fatty DLR on my Taurine and rebuilt the damper.
    Put 7.5w oil in and it doesn't feel very plush.
    Going to dismantle again and put in 5w oil.
    I am also wondering if I filled the oil incorrectly - I filled to the brim, cycled the shaft up and down a few times until air couldn't be heard - brimmed again and screwed the white top in. Should I leave a small air gap? I read somewhere there is a bleed screw somewhere, but couldn't find - is there one on the fatty DLR.

    Thanks for any help.

    Heahshok DLR damper Damper piston

    The official Lefty thread, tech, mechanical, etc-damper-piston.jpg

    I've stripped down my headshok DLR damper and wanted to check the damper valving and washers are in the correct order and orientation.
    I can't find any parts breakdown for the damper anywhere.
    It was assembled like this before - no air or oil leaks, but it didn't feel great - too stiff.
    Does this look right ?

    Thanks

    Can anyone help

    The official Lefty thread, tech, mechanical, etc-d3.jpg

    Can anyone tell me if the shaped washer which the arrow is pointing to is the wrong way round. It's just that this way round the holes get blocked when the shaft is tightened up and 2 nylon washers cover up the bottom of the washer so oil wouldn't seem to flow through. Thanks

    I have a Max 130 Fox Carbon that was serviced by Cannondale last year and they upgraded the internals to the version with the Poptop. The Lefty was bought on a Rize 2 that I bought new in 2011, but was a 2009 model I believe. This morning I noticed some oil on the outside of the boot, and when I took the lower clip off, a good amount of oil came out of the inside of the boot down the shaft. I am assuming this would indicate a blown seal? If so, is this something that an average home mechanic might attempt to remedy? Or am I best to send it in for a more pro job?

    Help and advice much appreciated, and apologies if this has been dealt with in the thread before...
    It's all Here. Now.

    Am I missing something on my bad boy?

    Hello

    I recently purchased a used Bad Boy Disc Solo.
    I'm concerned that I might be missing a spindle or something on the front fork/wheel. On the riders right side of the bike theres a allen screw and on the left side of the fork theres a threaded hole. I can see all the way in this hole.
    Should there be a spindle or is the allen screw on the right side all that holes the wheel to the fork? Hope that makes sense? See pictures below.
    Thank you!

    Nope, you are all good to go. The allen bolt on the non disc side threads into a spindle that is part of the fork.

    Hello, I have a problem with a Lefty DLR from a 2010 Flash F1. It won't lock, why could be the reason ? This afternoon I will go to the shop to do maintenance of fork.

    Also rebound wasn't working very well, I have no notice of changes on rebound when I turning dial.

    I have the Lefty Carbon Speed, and it's my first Lefty.
    I've set it up as well as I know how, but have issues.
    When I'm seated it works fine but when standing and haulling on the pedals, it's too squishy and makes that pshhh pshhh pshhh sound.
    It's been tuned by Mendon Cyclesmith, so I know it's in great condition, and obviously it only needs some adjustment.

    What to do?

    Does the Lefty ( 2013) have a sort of break in period ? I haven't used the bike much since I've got it early december and I've had to adjust the pressure in order to find an accettable fork compliance with very poor results anyway. I've started to use the bike more often this past month and the Lefty is now smooter and more compliant then ever,I've even brought it to it's suggested pressure for my weight and it just works the way it's supposed too.
    So,break in period you think ?

    Cannondale Lefty DLR 100 Year2000 Inner Race Replace

    Hi to every one, its my first time in this forum.
    I was reading through about cannondale Lefty DLR, but I could not find any thing related to the Lefty DLR 100 year 2000.
    I have a Cannondale Lefty F700sx of 2000, and I was making a mantenance to the fork.
    I realise, that the Inner Race are damage, so I was traing to separate the telescope, to replace the Inner and may be also the needles bearings.
    Could some one tell me how to do It?
    I alredy have open the upper part whit the Tool HDTL200, also toke out the upper clip which holds the inners, but from that point, Im lost... could some one tell me how to release the telescope from the rest....?

    Hi everyone,

    I have just got back in to biking again after quite a break (ex DH'er who found cars, beer etc) and have just got myself a Cannondale F800 second hand (more of an xc fan now I have grown up!). Its a great bike and I am quite good with with the mechanics (ex lbs worker) but I just have a quick question about the lefty as I have not ridden one before.


    It is a Lefty DLR (first version) and runs very smooth. No stiction (slightly noiser than the forks I used to run as you can almost hear the bearings rolling - but not rough at all).


    The question I have is how quick should the rebound be? With the red dial all the way to the right it is very slow, but with one 1/4 turn it speeds up hugely and almost begins to top out. The rebound is then the same all the way through the turning of the dial.


    As I ride a lot on the moors I hit some quite deep depressions and the fork tends to get stuck at the bottom of the travel and then catapult me over. This is only in deep but short bog holes or bombhills.


    Should there more rebound control and should the fork feel more progressive (at the moment it feels the same throguhout the travel - no harder at the bottom than the top).


    Ultimately I want to know if I need to spend the £100 require on a damper service or if this is 'normal' for a lefty of this age?


    Thanks again everyone!

    The official Lefty thread, tech, mechanical, etc

    I am really desperate for help on self servicing my lefty here in The UK. more specifically, I am hoping to service the damper on my brilliant Lefty Max 140 pbr from my beautiful rz140. I have spent a good few hours trawling these threads to find a guide on how to do this on this specific model but seem to be getting no where on the specific procedure for this model. Can anyone help?
    I want to top up or replace the oil on the damper as it is getting a little clunky and lock out is poor (and maybe change seals etc).
    I would like to know the general procedure, which tool is needed to remove the damper, how to replace the oil and which oil is best.

    Thanks
    Morgs

    Hello!
    Please tell me where I can get Lefty XLR 100 26'er service manual?
    Can I convert it to 29er fork - as I understand, I've to put 3 travel reducers, and I'll get 70 mm 29er fork?
    and last question - is there any way to remove remote lever but make fork to stay unblocked without this lever?

    Can anyone tell me what the difference is between the 2011 and 2012 LEFTY SPEED PBR, 100MM, OPI, SOLO AIR fork?
    Are they the same?

    Reason being I bought a 2nd hand Flash 1 alloy 2012 but I can get a 2011 brand new Flash 1 so just wondering what the main differences are and if it's worth keeping the 2nd hand 2012 bike or return it and buy the new 2011 model?

    I want to find service manual, including damper service, for example.

    Ok so now arise a new problem I'd like to share. I have the 130 PBR carbon on my tandem inflate at 160PSI. While I'm ridding my fork is gradually going down, down, down in its travel to end at zero. I'd just need to unweight the bike and then the fork is coming up again, no pressure loose ! Is this a magical thing ? What's happening ?

    Maybe you're loosing air in that fork?! when you unsaddle and go back in, is it the same and it bottoms out?

    Hi, well no I'm not using air, it's just that while riding FLAT it's going maybe in the negative chamber and the fork compress in several minutes to travel zero. Just unload the front several times and everything goes back to normal with its 130mm travel
    What the h... ????

    does the fork feel regular while it's high in travel? I mean compression, rebound...

    Yes I have a shock pump, and there is NO loss of pressure. I think that pressure is migrating to the negative air chamber (if there is one) and back when unload

    Big disappointment, new Lefty Carbon XLR 100

    Hello everybody

    Finally got the chance to hop on my new Scalpel 1 29er. After a few miles I had to interrupt the ride because the fork was not performing anymore. I found out that within minutes, the fork had "travelled down" and now rested at the very bottom point. When I dragged the bike up, the fork (very slowly) came back into the initial position. Since the bike comes with a remote lockout, I tried it locked too but the same thing happened. I tried to work with the rebound whhel for some time, but it didn't make much of a difference. The pressure is fine at 11.4 bar.

    Fork: NEW LEFTY CARBON XLR 100 29, HYBRID NEEDLE BEARING TECHNOLOGY

    Any ideas?

    Thanks and bye.

    Exactly the same thing that keeps hapenning to me. I think it's a transfert of air pressure between positive and negative air chambers. But if someone can give us THE cure for this phenomena... he will have a great thanks from both of us !!!

    The official Lefty thread, tech, mechanical, etc

    I want to top up or replace the oil on the damper as it is getting a little clunky and lock out is poor (and maybe change seals etc).
    I would like to know the general procedure, which tool is needed to remove the damper, how to replace the oil and which oil is best.

    Thanks

    Ok, I have now got hold of a
    Castle to and removed the damper. To be honest it seems if e, however I have noticed the top inner race has come loose and was floating around when I removed the damper. Is this a major problem? Does it just Lay on the bearing cages (with the slots going over the bearing tops) or should it be forced down and clipped into place? I am a little worried that I have overly forced the lefty during a bearing reset and some how dislodged the races (hence causing the clunkyness at full extension

    Got a leak at the lower oil cap of my Lefty Ultra Carbon and it has only done about 1500km. Replaced the seal with a new one, but still oil is leaking from between the shaft and the oil cap. There are no damages to the shaft. The orientation of the seal is with the opening facing the inside of the damper (it's kind of V shaped). What am I doing wrong?

    It's an oil problem on the damper! I just pulled out my damper, cleaned it and filled it with 10wt maxima damper fluid and it works perfect now

    Hi I need help with servicing a 2010 Lefty speed carbon SL DLR. I only have the owner's manual and I think I need more than that. My Lefty, which had been riding fine for a year, has completely lost its punch. The last ride felt like I had no suspension at all. Air pressure is good, I did notice a little oil leaking around the air valve at the bottom. Before I tear this apart and ruin it, as is my usual process, what else can I check/do/read and get informed about?

    Too plush ?

    I just picked up an 09 rize three with the PBR lefty Max, this is my first experience with the lefty, my question may seem strange, but here it is. At 140 psi my fork seems almost too plush, I can compress almost all the travel by pushing down on the bars, I'm 180 lbs. can anyone offer some advice, even if it's only what most people are running as far as pressure, thanks
