What tool do I need? #1
I’m un-sure which tools to use to remove the crank and cartridge sealed BB on my bike. The specs are here:

They are usually 15mm. But who knows, maybe yours is smaller?
You'll need a crank puller. |

Unbolt the center screw, then use the crank remover. http://www.sheldonbrown.com/gloss_cn-z.html#crankpuller |
12.9 is the grade of the bolt, not the size.
|
Okay so these crank pullers, do they come in different sizes? And is this one okay?

the one you have linked is pretty versatile. It'll probably work fine

It looks pretty standard- if so then you'll need a 14 mm or 15 thin-walled socket to remove the bolt, and a crank puller to remove the crank. Don't despair, these are relatively inexpensive tools. Buy them locally, then if they don't fit, you can take them back. Also, there are a few sizes of threads in cranks for the puller to thread into, but it's likely you have the most common version (22x1mm):

No, a socket takes the bolt out. The puller pulls the crank off.
You don't regrease cartridge bottom brackets. You throw them away and put in a new one. |

Okay, but it’s removable to check for water interference?
Unless you want to take it apart for fun or for a learning experience, or a fun learning experience, then it's not worth it. |
So I’ve bought some sockets, and I’ve also bought the crank puller. Is that all I need for now?
|
Yes, but as noted, in order to remove the bottom bracket, you'll also need to buy a BB tool, probably something like this: http://www.parktool.com/products/det...25&item=BBT-22

Without a photo of what you are seeing once the cranks are out of the way, Mondoman may be correct on his guess, but don't buy one until you (or we) confirm the identity of the bottom-bracket.

Thanks, p7!

Okay so when I’ve got the tools to take out the crank, I’ll post some photos. Thanks.
