Put a lock on my front wheel when I left it outside the garage and went to the shop for a min, then forgot, moved the bike and snapped a thingy whatsit. blolox.
On the left side of the front wheel is a cable, is this the speedo cable? Is it easy to replace?

30 seconds to change.
undo at the clocks and at the same at the speedo drive. should be able to undo it by hand.

Simple to replace and can be bought from wemoto
