    Need to remove cranks from BB

    I posted this earlier in the wrong forum, so here is a copy and paste of the post in the Mountain Biking Forum:


    I recently purchased RaceFace Prodigy XC cranks with a RaceFace SRX bottom bracket. I have not put these cranks on yet, as I need the proper tools that I will be buying tommorow. My problem is that I got too anxious and went ahead and attached the both crank arms to the bottom bracket outside of the bike. I tightened the allen screw snugly, but not too tight. I then thought it would be easy to remove the crank arms off the bottom bracket for installation, but I cannot get them off with my bare hands. I know that there are crank extractors, but I am not sure how they work. So will I be able to remove the cranks from the bottom bracket using a crank extractor? Or does anyone have any other methods?

    Thanks in advance!

    Im not sure, but possible grease it in some way? Maybe it'll slide off...

    Also, if you have a vice, or something that will grip the cranks, wraps them up in a cloth so they dont mark the cranks, and then use a soft ended mallet and tap it off gently, possible both of these methods will work, they may even work well together

    I'd read the tech material that came with the cranks and bottom bracket; I believe you're supposed to be able to remove race face x series stuff without any other tools. You could also do a search for their website. Don't know,cause have I never worked on your type of crank. If you need a specialized tool, I'd get that-- it would avoid any potential damage. The proper tool saves you a lot of headaches, so I'd first find out what it is. From what little I know of Race Face cranks, you may have that tool in your box.
