Not the wife noooo.But when i'm climbing or putting the power down my crank makes a right old racket.I've oiled it with spray oil but this only worked for a short amount of time.Will greasing be the way forward.Thanks
I'll bet £100 its not your cranks, its also not your BB either...
Check to see if you have worn cleats, tension is correct, dirty cleats, re-grease up the screws. etc
if you are pretty sure it is the cranks then it might also be the bottom bracket. if you have the tools then take the cranks off and check the bb bearings for wear (might be that they are moving under load).
I've got two new pairs. Both creaked like buggery for a few months. Even tried two seats of different cleats. Once the shoes bed in and the cleats bed in it will go away.
I would say it will be very rare for it to be the cranks or BB. For peace of mind you could do as Ris says but I really think its coming from the shoes/ cleats
Meanwhile see http://sheldonbrown.com/creaks.html.
I had a creak - at 2 o'clock under power. My LBS literally rebuilt the whole bike with a bucket of grease before coming to the conclusion that there was a problem internally to the 105 cranks themselves.
And did he check the cleats/ pedals etc... Internally to the 105 cranks themselves...hmmm
The LBS mechanic started by greasing and tightening everything. No joy.
He got really annoyed he couldnt track it and became obsessed for a week - he worked on it in his spare time, no charge. Good shop.
They tried new bits on everything, finally replacing the 105 crank with another - the creak went; then they put the original back on and it came back.
That was back in my heavy days , lost 2.5 stone since. Back then I had to put down the power of an elephant just to hit 20kph.
