My new sensor is IGPSport, and seems a whisker thinner than my dearly departed one. I tucked this one on the NDS arm, almost touching the BB. Just have 10 miles so far, may add some tape, or I am thinking of fabricating a wide rubber band from an old road inner tube for a bit more security, if there's enough clearance. Yeah it's a snug fit. Not near the bike for a picture.
