I have idea reguarding the wiring of my CATEYE, but thought I would bounce it off of the net first. Is there any reason I can't put the wires through the frame? I would have to drill a small hole in the back of the bottom bracket and back of the head tube. Would this hurt my frame? Also, I would need to cut (and splice) the sensing wires. Is this coax or just a twisted pair? It looks small enough to be tricky to work with. barry steel

There are two MAJOR problems: stress cracks radiating from the hole, and entry of moisture. The second can be handled with RTV or caulk, but the stress cracks will eventually ruin your frame. The problem is compounded by where you propose to drill -- stress is greatest at the tube ends. If you INSIST on so maiming your frame, try to drill through a lug, which will relieve the stress cracking problem somewhat. (There are cyclists in hospitals right now who drilled their handlebars to get rid of those unsightly brake cables!) -- :::::: Jan Steinman Box 1000, MS 61-161 (w)503/685-2843 :::::: :::::: tektronix!tekecs!jans Wilsonville, OR 97070 (h)503/657-7703 ::::::

Moots (Steamboat Springs, CO) also predrills their frames AND wires for lights, I would be suprised to see one of their frames fall apart.
