Replacement Shimano buckles?

[Steve Clark]

Can anyone refer my to a US or Canadian dealer for these replacement parts. I found them on a UK site but would rather shop a bit closer to home. I broke one today.

You can put Sidi buckles on, if you use their ladder straps and also their mounting bolt. If you use the shimano mounting bolt with the Sidi buckle it will stick out too far and you won't be able to undo the strap.
