Question about Sport & Outdoor - Others
I need to change the crankset but i don't know how
It depends of course.
If you see something like this: TRADITIONAL CRANK except that there are plastic or metal covers over the bolt holes, then you'll need a socket wrench and a crank puller. First pop off the plastic or metal cap and then, with a 9/16ths or other socket, remove the nut (or it may be a bolt) underneath. This should screw on with traditional threading (righty, tighty... lefty loosy). Then use the crank puller to remove the crank by first screwing in the large threaded part into the crank and then turning the handle to pop off the crank. If you don't have a crank puller you could try biking for a mile or two with the cranks unbolted, you might wiggle it free, but these are designed to be perfectly matched and you don't want to screw up your axil, so I'd suggest the $12 tool.
If you have .... nevermind
This is easier:
Go to Park Tools website and follow their great instructions:
CRANK REMOVAL & INSTALLATION
They have pretty pictures and great walk throughs on many topics.
