I recently (2 months ago) bought my first set of clipless pedals (first pedals I have ever bought, just used default ones before). Shimano M545. All was well till this morning when I noticed that the left pedal has lost the bolt on the side that holds it together, (think its called the cap unit bolt). This cap unit bolt and the washer bits have disappeared, presumably during a ride. Here is a link to shimano's site that shows the pedal and the cap unit bolt bit:
I took it to my local bike shop and they say they do not have a bolt for it. Can this sort of thing be found / bought and replaced or do I have to replace the whole pedal?
I bought it from Wiggle and have just contacted them about the issue but wanted the advice from the community about how I can deal with this situation.
