TraceR Aero Seat Post Bracket

On my Pinarello F7, the seatpost is V-shaped on the front side, and goes on a flat surface on the back side. Silicone rubber is also V-shaped, and would be perfect for the front side of a seatpost. But, silicone rubber is soft, and is very easily shaped, so there is no problem to put it on the back side, holding firmly to the seatpost.

Fits my Boardman Air TT 9.4 deep aero seat post and held the TraceR in place for a couple of training rides and a 190km triathlon bike leg - so works!

It holds the light straight on my aero seat post. Occasionally the light bracket moves to one side but that’s usually caused by the rubber strap not having equal tension. Other than that it works very well.
