    Lefty build for dummies...

    Looking for a parts list for building a fat Lefty. Can someone check the
    list and add/change/advise etc?
    If you were just going out and purchasing everything for a complete build.
    1. Lefty shock: DLR/ELO/Max etc (non bonded clamps)
    2. MCS clamps
    3. Lefty Hub: cannondale/Project 321 etc
    Axle Cap & Bolt
    lefty O ring seals or bearing covers needed or do they come with the new OEM hub?
    4. Rim 65mm~100mm rim dual hole drilled
    5. Spokes/nipples - use freespoke or send to builder/MCS
    6. Rotor


    Anything I'm missing?
    thank you

    Longer clamps which connect the fork leg to the head tube/headset. This allows wide tires while preserving normal handling.

    Another question:

    Uber drop vs standard:
    Is there a measurement or spot needed to know which clamps will work?
    Headtube measurement of 12cm.

    Total stack is what you need to know.

    Standards are 165mm max

    Ubers are 188mm max.

    So with a 120mm ht, average hs stack being about 30mm, you're easily in the standard range....

    Just FYI, searching with 29er as a parameter will turn up a ton of modern forks, ones that won't work.

    Better to stick to 26, or, DLR titanium, Max 130 or 140, alloy, etc.....

    A year ago it was much easier to find cheap lefties, they were all over eBay etc....
    Not so much now.

    I just paid 400 for a max, plus had MCS service it. Still the best fat front sus option IMO

    There is a lefty max listed on Facebook fat bike trader. It was listed in June so you have to scroll down the page. Does not say it was sold.

    I was thinking....why can't you use a lefty with bonded clamps? If you are replacing the clamps, can't you just take a dremmel with a fiber cutting wheel and cut the bonded clamps off?

    Someone did that, used a metal lathe and machined off the bonded clamps....
    Much easier to unbolt....

    Ok, not sure why you would have to use a lathe....fiber wheels go through AL like butter, the trick is to not go to deep.I would think you could 3 cut them and then just give them a little smack....My concern is where the tube is able to accept the clamp...the bonded ones the area may be ver small.....I am asking because in looking for leftys, there seems to not be that many around....( note: no ebay for me, been burned to many times)

    The primary issue is that the threads which the top collar screws onto (top collar holds the whole shebang together), are part of the upper clamp. Cut the clamp off, you cut off the means of holding everything together. As mentioned, it's tricky to cut off just enough, do too much, and you've ruined your fork for any purpose. Also, the carbon chassis were never designed or built to be clamped, and I won't be the one to tell you that the structure will be fine if you do.

    A few folks have done various approaches, some kind of slick and well thought out, but one off and pricey to try unless you have a machine shop in your life, others, I shake my head and disassociate with as they were so sketchy.

    End of the day, if you want to order it up, plug and play by the end of the week, buy a Bluto. Want to save some $, and are willing to dig a bit and wait, the Lefty will be awesome (had a fork in the shop yesterday, guy bought it for $50 with a hub, sent it back with a pair of clamps, serviced, travel limited ready to roll, under $300).

    Want a very future proof, stiff, plush, adjustable a2c and travel fork that can do, Fatty, 26, 650B, 29 and 29+, all in one fork with two sets of clamps? Yeah, Lefty does all that too.

    Thanks...thats what I was asking..the problem is I have a bike with a 1 1/8 steerer...so the bludo is out. If I want front suspention( I live in nj, the land of a billon rocks), seems the lefty is the only option...that or some kind of double crown thing but then I have to worry about getting the front end to tall and maybe snapping a head tube..

    Bluto is offered in a straight steerer, just FYI, but I'd still get a Lefty

    Yea, I asked a rep...he said no 1 1/8 steerers.....tapered or go home...as far as I know. Seems a lot of the new fatties will have tappered steerers in 2015...want to avoid buying a new frame.

    Spoke with our Aussie suppliers two days go and he had just got the tech doc/parts docs through. Definitely no straight steered, tapered only.

    (MCS) I just bought a bike equipped with an MCS Lefty Max conversions. It's currently running a Surly Nate on a Holy Rolling Darryl. Will the Lefty allow me to mount a Surly Bud?

    Not MCS here but I do have two of his Lefties and yes you can mount a Bud or any other huge tire on that fork. If it runs too close to the fork you just redish the rim to gain the required clearance then loosen the fork clamps and rotate the fork in the clamps till the tire is centered in the head tube. Tighten the clamps and your good.
    I am running Bud/Clownshoe on mine..

    Rotation is for centering the tire to the head tube. Tire/fork clearance is obtained by dish. I have never riden either of our fat bikes with a stock fork so I have nothing to compare it to as far as offset.

    yeah, i meant, lets say you went from a 3.8 to a 4.8" tyre, and you want to have the tyre central, you would want to move the fork leg away from the midline, thus affordign more room for the tyre, so you would rotate the fork leg in the clamps (presumably) so that the clamps are at a greater angle from the line described by the radius of the tyre, which to my mind would decreasee the fork offset, and also you would re dish the wheel to centre it.

    im wonderign if the offset reduction is significant? (and i doubt it!)

    Yep, probably some guys out there might notice a difference, doubt it would be much though, we're talking the fork leg moving out an extra 1/2", which translates to not very much angle/offset difference in reality.

    My guess is you will notice the extra overall height/head angle if you goo too high. (I did not notice a change from stock pugs fork on my 9zero to a Maverick or lefty DLR (100mm), but I did notice a handling difference after going to the lefty max this last time)

    Within the "working range" the difference is very slight from "skinny" fat, to fat fat.

    Beyond that range, sure, it would impact things for certain....
