    I can't see putting a lefty on a Superfly...why would you want to do that? It would be a lot of cost to do so and I can't see that their forks are better than the SID you are considering. Plus a Trek Superfly with a Cannondale Lefty fork just wouldn't look right at all. Just my 2 cents.

    I recently put a lefty onto my fatbike, I know, much different application, but I ride my fatty year-round and mostly singletrack, from fast and flowy to old-school rugged stuff.
    The lefty made a huge difference. Even with a 4" wide tire, this thing is the stiffest fork I've ridden. No flex under hard turns or braking.

    You will likely need an adapter of some sort to make a lefty work with your frame, but imho it would be worth the effort.

    Most of the people that badmouth the lefty have never ridden one before.


    Bonus, you can swap tire/tube without removing from bike

    Downside, a bit more effort removing wheel as the brake caliper can be in the way, might be a factor depending what type of rack you have if you need to remove wheel regularly or not. I use a thule sidearm so I very rarely have to remove front wheel.

    LOL....how is that any different than putting a RockShox or Fox fork on? Last time I checked Trek doesn't make forks either....

    Lefty is a great riding fork. Keep on track with the bearing reset (easy and quick to do), match up the right version (based on your head tube height, snag a Project321 adaptor and you're good to go.

    The difference is that RockShox and Fox don't make bikes, their forks are (generally) a universal fit to all makes of bike. Cannondale makes bikes, and forks specifically to work with those bikes. In order to make a Lefty work with a non-Cannondale bike, an aftermarket adapter (Project321) is required, and up till a few years ago, was not even possible.

    That being said, if someone wants to put a Lefty on their Trek or any other bike, and they have the cash to do it, then more power to them. It's your bike, ride what you like.

    Corbin, don't forget that you'll need a new front wheel/hub to run the Lefty.

    Jeff, I have the feeling you think this is not a good idea, I would like to have some of your input..What you think?

    I wouldn't say that I think it's not a good idea, I'm just not convinced it would be better than what you have now. Keep in mind that I've never been a Cannondale fan, and have never ridden a Lefty. I think when the Lefty was designed, thru axle forks didn't exist, and I can readily believe that the Lefty is stiffer than a standard 9mm open dropout fork. Nowadays, and Cannondale fans will probably say otherwise, I just do not believe that a Lefty could be as stiff as a high end fork with a thru axle, at least not with a larger rider like myself. So the positives, to me, are a wash. The negatives are the axle size that doesn't work on any other fork, the decreased turning radius on the left side, and unless something has changed in the last few years, you can only get it serviced by taking it to a Cannondale dealer (and the dealer in Tampa is not a place I would ever want to deal with). Also, the handling of the bike will most likely change as I doubt the Lefty has the 51mm fork offset. But that's me. If you want it, go for it. We probably can't source the Lefty or 321 parts (aside from ordering it just like you can), but we'll gladly install the stuff, and we can definitely work out the wheel issue with either a new wheel or relacing a new hub into your existing rim.
