Hi all - my first post here. I have a question, and suspect it's been addressed and I am not looking in the right place. I have a Garmin Edge 305 with cadence counter. Lost the cadence magnet, but have ordered a new one. The problem I am having is that the crank arms on my bike are hollowed out/curved on the inside, and as a result, I haven't been able to mount the magnet close enough for it to be read by the cadence counter. It also doesn't fit tightly, which is why it got lost in the first place. Any suggestions? I've been reading quite a few of the posts on saddles and finding them very helpful. Thank you for all the information.
