    Lefty Preload Spring Question

    I have an 05 medium Prophet with the Lefty Max 140 FFD. I weigh close to 200 with all my gear. If I preload the red spring with the maximum 8 turns, would that be about the same as changing to a black spring or should I just get a black spring? Is there a titanium equivalent of the black spring that will work in my Lefty model? Thanks.

    I didnt find changing the preload of the red to max the same as an unloaded black. I ended up switching to the blk to reduce fork dive.

    I believe the Ti springs only go up to red. They were intended to be used with the SPV Lefty max witch used a softer spring for the same given weight vs the FFD and TPC

    I weigh about 180 and I tried both the black and red with my FFD. The red was definitely too 'springy' no matter what the preload setting. I much prefer the black.

    check the spring weight guide

    check the spring for your weights i think 220 for the FFD and TCP are a brown spring. the black spring is for 170-200 i think. there is a post on the cannondale forum that list the weights for each spring.

    The stiffest spring that Cannondale sells for the FFD140 is part number KF213/BRN and is a Brown spring. It is rated for 200-220 lbs.

    I am in the process of swapping my factory installed black spring (rated 170-199) for the aforementioned unit. I weigh in at 195+/- and prefer a stiffer set up.

    Only $32.00 at the lbs.

    I went ahead and got the black spring. I think something was wrong with the way it was assembled originally because the rebound knob did nothing and I couldn't even bottom it out by pushing down on it. When I had both springs out I could tell the black one was stiffer but after putting it back together I can actually bottom out the black spring by pushing down on it and the rebound knob is working now. It's strange that I can bottom out the black but not the red but I'm excited to try it out tomorrow.

    The 140 FFD is the "low end lefty". Having said that when assembled correctly the fork rebound knob will make a noticible difference in action.

    Did you put the new spring in? If so good for you that is a bit of a job.

    What is your weight?

    Another thing about the FFD is that make sure the air bleed is working. This means on fork compression you will hear the sound of air leaving the fork aka normal.

    Have fun testing.

    hey, let me get in here...i've just got an '07 prophet with FFD lefty...i have the red spring inside and it has too much dive for me...i weigh 180 plus ten pounds or so of gear..like trying to bunnyhop and the fork just dives too much...or pulling wheelies.

    it's still quite ridable but i think i need a higher rated spring...so am i understanding correctly, that the black spring is the next level and then the brown spring is the stiffest spring available

    thanks!

    If you check the Cannondale web site you can find a comprehensive list of springs and applications as for all types of Leftys.

    Having said that the simple version of FFD 140 springs (3 firmest) is as follows (by part number):

    KF213/RED listed as firm 150-169 lbs. rider weight
    KF213/BLK listed as X firm 170-199 lbs. rider weight
    KF213/BRN listed at XX firm 200-220 lbs. rider weight

    When looking at spring charts pay attention to which fork it is for i.e. (Carbon, titanium, SPV, TPC, etc.)

    Good luck!

    Any chance you are in So Cal check out Helens Bike Shop in Santa Monica. I got my spring from them no big issue.

    When is Mammoth (I trust that is Mammoth CA) ?

    i ended up getting my parts from Mendon cycle in NY and i had to ship my ffd to them for an upgrade to the TCP kit with a brown spring. im at 200lb with out gear so i think the brown will be perfect. im use to a bit stiffer set up. i live in san clemente ca and i might end up selling the black spring once i decided if i like the firmness of the brown.
