ISP topper slight problem...I was hoping to add one of these 'toppers' to give it a nice sleek look at the top
and NOT the normal, clunkier topper that fits on the outside (the cleanest of which looks like this:)
However, owing to the bike being titanium (with thicker walls), the internal measurements are narrower than the (internal) topper (first pic) will allow (it's 30.6mm, as measured with calipers, as opposed to a crabon frame that would normally have a wider opening. Ooo er).
So...I can either simply buy the ISP topper in the second pic.
OR...
Is it super mental to just get a normal seatpost (that measures 30.6mm), chop a lot of it off, then either
a) Insert it and load up on JB weld to keep it in place
b) Insert it and drill a (3ish mm) hole through the frame (just below the tip of the ti seat mast), and seatpost and bolt it in place (will be 2 holes, in one side and out the other)
c) Create a 'notch' in the rim of the ti frame, then have a bolt in the seatpost on one side (to control the side to side sway, with the up and down motion held in by friction
I know it's a little bit silly, but on a scale of 1 to 10...??
