Hello again..

This is an illustration of the helmet mount made from a cut bicycle inner as described in message #1043

Pic #1: Top view.. with Cateye HL1500.. with zip tie to close the inner tube loop. Zip tie should be cut to length..and the inner tube knot correctly shifted to inside of helmet. For illustration only.

Pic #2: Side view.. Cateye HL1500 properly secured on the helmet.

Much obliged.
Nick Lee
