I'm sorry but I believe you have this posted in the wrong product category? Please re-post the question in the proper category if this is the case, otherwise you have my apologies. This is the car and truck problem category

Since there are a lot of varieties of the Lefty go here and search the list for "LEFTY".

Or you might just get away with deflating the pressure preload and collapsing the fork.

Hello ledpencil,
Pneumatic bike shocks require a special type of pump called a "shock pump" that is a high-pressure (up to 300psi!) but low-volume pump. They come with a very accurate gauge, pump handle, and a bleed valve/button to let off puffs of air to soften the shock. They also have a long flexible neck that screws onto the valve at the base of the fork. They're relatively small and moderately priced ($20-$40) and can be packed in a riding pack in case you want to change the stiffness on the fly. Here's a link to some online: http://www.jensonusa.com/store/sub/292-Pumps+And+Co2+Inflation-Shock+Pumps.aspx?s=1559&mfg=0&closeoutHotdeal=&use=&sort=Default&show=25&pricemin=0&pricemax=100

I have a set of SKS X3's for my Jekyll with a Lefty. The front has a special large insert for the headshock-sized opening at the bottom of the steerer tube. Maybe check with a Cannondale-shop to find one.

Here's another solution at the bottom...

the XC3 stem comes in a 1.5 in clamp designed to fit on cannondale headshox systems. The lefty fork you have may or may not be compatible, you would have to check your fork to see if it is the right size.

There is an XC3 SL conversion kit for lefty forks that are not the same size and includes the stem and steerer replacement.

Swapping stems is quite easy on the cannondale. Loosen the two bolts holding the stem to the steerer and undo the bolts holding the handlebars, remove stem and replace.

If none of this makes sense then I would strongly urge you too take the bike into your local bike shop, preferrably a cannondale dealer, and have them show you. It will take only a couple minutes and they can confirm compatibility.

Hi!

The Cannondale Lefty fork can only be disassembled with speciality tools. You can read illustrated instructions here: http://www.gordlaw.com/index.php?Cycling:Cannondale_Lefty_DLR


Please check that your Lefty fork is identical to the one described, as the process and tools are different for the various Lefty editions.

As a warning, dismantling the fork could lead to serious injury if you don't know what you are doing. Please read through and understand all instructions before deciding whether to do it or not. Good luck.
