Hi,
One of the great advantages of the Phaserunner is it's low weight, but when you add a big heat sink you kind of negate that. Especially when you have such a huge heat sink beneath your legs. (the bike frame)
I would have liked to use the frame as a heatsink, but the frame is hydroformed - so it doesn't have any symmetrical cross section parts which you can match with any existing market heatsink: For example, you can find a heatsink which is intended to wrap a circle or even ellipse, but as the frame is neither one of those, you will not have full contact but only at some points.
Rubber is excellent for expanding the contact area, but rubber is heat insulator... In fact, every solid which is flexible is heat insulator.
The last idea I've had, is to create an intermediate&sealed volume between the body of the Phaserunner and the frame, which would be filled with some sort of cooling fluid - but those are only effective when they come in large volume and being pumped around in a cooling/heating circulation.
Does anyone has an idea, or did use his bicycle frame for this purpose, with success?
