Speed transmitter for Giant oval front fork
 

I have a Giant OCR 2 with oval front forks. I've tried a few different transmitters (Specialized, Sigma, Trek, to name a couple) and every one has failed to hold position on the fork.

There's nothing more distracting than losing all one's data mid-ride, stopping to adjust, and having it fail again.

Anyone have a remedy to this problem?

Thanks.

Put sensor on rear wheel seat stay or chain stay???
