I went shopping this morning for a replacement for my Garmin heart rate monitor strap which carked it at the Mont, and bought a speed and cadence sensor as well, with the aim of fitting to my Cannondale Rize.

Got home, ripped open the packaging and read the instructions (yeah, I do that - weird, huh?) then went to put it on the non-drive side chain stay and .... stopped.

Bugger. How's this gonna work?
