thought that might be the case! At the mo i am riding a standard monty
trials uni. i wasnt quite sure how to get the crank off though. I can
unscrew the main nut, but then where do i go from there.. the crank is
still firmly attatched

Eeek, I'm as lost as you are!

What hub does the Monty Trial's have (It's not splinted is it?

My nimbus Trials set is about to give up so I'm planning to buy a new
crankset aswell, so is another guy on the forum aswell! You won't be
the only one!

I wouldn't rush into buying a new crankset just yet, it might be
fixable, but will probably need to be replaced eventually.

Send in some pictures? Pictures are nice.

To pull the crank off you need a crank puller(extractor) tool, about £8
from UDC or your local bike shop. If only the crank is bent, then
removing it and replacing it with a new one will be fine. If you've
damaged the hub aswell, i.e. when you remove the crank the square peg
that it fits on to is bent/cracked, then you need a new hub, and
splined is probably the way to go. Splined means that the end of the
axles looks like a gear, with lots of teeth, rather than a square
cross-section that tapers, like a square taper (which is what you have
at the moment) Have a look at photos of splined and square taper hubs
on UDC to see what i mean. All you need to know is that splined means
massive strength, well worth having. If you keep replacing your
equipment with what you have already you'll keep breaking it, if you
upgrade it will last alot longer and be cheaper in the long run.

splined is beter because there is more surface aira for the hub and
crank to interlock and they are normaly bult to be more befey

'THIS' (http://www.unicyclist.com/forums/showthread.php?t=38277) can
tell you just about everything you need to know about square/splined
cranks.

Don't try to bend them back the other way, it will most likely snap.
