Thanks for all the help folks. Those caps came off very easily using an Israeli 1 shekel piece and some pliers! The seat post came out after some serious elbow grease also.
Now, to ask a stupid question - the 14mm bolts on the crank are ordinary threads, right? As in, you turn them anti-clockwise... I've had them soaking in GT85 for 3 days and managed to finally budge the drive side one today but the left hand one will not move.
Cheers
