Problem when I pedal

[MARK170881]

Thanks for the replies..

Right, I've ordered a crank puller which should be with me Thursday £3.45 delivered (thank you ebay )

I've managed to source a new front crank that should be with me by the weekend.

I'll get the other pictures of the middle part of the crank & the other side when I get in from work tonight.

I'll also post a picture of the rear cluster tonight and could you let me know if you also think these will need replacing
