    Prophet lefty max loose headset

    Had the bike over a year now and finally the headset has come loose.. pretty good going I think. Its defiantly the headset and not the lefty.

    Anyway.. how on earth do you tighten the thing up? Thought I would ask before disassembling everything. I cant see any obvious ways to do it?

    Cheers in advance

    It's press fit, not adjustable, Once it's loose, rough, gritty, you install a new one.... but only one year? These are very durable, usually lasting a few years easily.

    You should need new bearings only, removing the Lefty is easy. Download the manual for your specific fork from Cannondale website and it should have instructions on how to remove it.

    Ok great.. yea im confident about getting the lefty off... Is it tricky to get the old bearings out and the new ones in?

    You have to tap the top of the steerer tube with a rubber mallet.
    The bottom bearing will come out of it's cup and will stay on the steerer tube, and the fork will come out.
    (Make sure you hold the fork with 1 hand as you're doing so to keep it from falling)
    The top bearing will stay in place.
    Use a piece of wood (I always a piece of a bird cage perch) and tap around on the upper bearing from the inside.
    Sometimes it pops right out by hand though.
    Same for the bearing that remains on the steerer tube: Slowly tap around it to bring it up.
    DON'T KEEP HITTING IT FROM ONE SIDE! MAKE SURE YOU TAP ONCE @ 12'clock, 6'clock, 9'clock & 3'clock positions. First it might feel like it's not moving at all, but do it a couple of times in the above mentioned order and you'll be fine.

    Makes sense.. that steerer tube is stuck fast however.. given it a few good tonks with the mallet but nothing. did yours come out easily?

    Juup. It could be that there's a little bit corrosion on the matting surfaces of the bearings.
    Just keep hitting it and it'll work.Try to soak it with liquid wrench or WD40 for a bit also and I bet it'll budge. Just make sure that you don't hit it too hard and maybe bent the steering tube.
    If you install the new bearings apply a tiny bit of grease and they'll slide easier in place.
    Also that will make it easier for you to take 'em out later when you need to replace them again.

    Indeed.. I did have to give them a good few hits to get the steerer out. It did help that I gave it a WD40 soak overnight to loosen it all up. No problems it came in the end Thanks for the rest of the tips.. got the jobs done in the end... its pretty easy when you know how eh

    cheers cdalemaniac
