Heres the deal with aluminum bars and handwarmers. I recently ordered a set of
Cat titanium mtn bars for my summit on snowest. Before I made a decision I asked if anybody knew the heat conductivity Ti as compared to steel and aluminum as I know the aluminum really conducts heat. Somebody posted that aluminum conducts heat about 5 times better than steel and the Ti only about half of what steel does.
I have run into probs with heaters on bikes. You have to insulate the heating element from the bar metal. I used a layer of cloth tape (hockey tape) covered by duct tape and then soaped up my grips and forced them on. The bar acts as a heat-sink.
