Hollowgram Si Crankset Weight

The install is pretty easy.1. Put the bearing cover on the NDS.2. Install the spindle from the NDS - you may need to use a rubber mallet to get it in.

I have a plastic dead-blow hammer I use.3. Install DS bearing shield, wavy washer and spacers. (I suggest you not start with more than three spacers)4. Install DS arm. (I think torque on that is about 41nm, IIRC - I keep the install manual in my tool chest for reference)5. Install NDS arm.Here is the one caveat: If you install too many spacers on the DS, the crank will not spin freely.If you have to remove the crank, yes, you need a special tool - the Cannondale KT013. It costs about $20, if I remember correctly and your Cannondale dealer can order it for you.

For removing the old crank; remove one arm on the fsa (assuming the FSA has got the bb30 shaft molded/pressed onto one arm) use an air-can upside down, and spray this in the spindle. It cools down the spindle to a very low temp, a small blow with a rubber hammer should move the spindle and you should be able to pull it right out. Pulling in a straight line is a must, the bearings can lock-up and damage the bearing-facesFor installing the SiSL, cool down the spindle and heat up the bearings with a hair-dryer. This works miracles and makes installing it very simple. Tolerances are quite tight on the spindle/bearings. (for installing, the last thing you really want to do is use a hammer to force it in place, especially with ceramic bearings.

I'm currently working on a tool to pull the spindle in and out.Best tool i've came across to remove/install bearings in the bottom bracket is from enduro.Not a big fan of the parktools removal tool, you shouldn't use a hammer to remove bearings.The KT013 is a must have for taking off the arms, if you also want to change the spider, the KT012 tool is required.Use grease on the spindle, it makes installing a tad easier and should prevent the bearings contact-area from rust with a creaking result. I had spoke directly to a Cannondale engineer last fall and at the time they were doing a running change on the spiders.

When set-up on a PF30 there wasn't clearance between the spider and the rounded portion of the cartridge where the bearing sits. I tried to install one last year on the Evo and you can get it on, but to much pre-load on the bearings. Once I had the newer version, so issues. If you look at the older spider and the new one, you can see where they had milled out an area that sits inside against the PF.
