I've got a Cervelo P2C, with an xlab cage thing off the seat, Adamo Road saddle back there. So, I've rigged up a rather unreliable rubber band to hold a rear LED super-flash. The rubber band is tied between the two carbon drink cages, and is clipped into the rubber band. The super flash, comes off and is not secure.
The standard seat post device from which the LED rear light attaches is intended for round seat posts, I have found none to be able to go around a seat post like the P2.
I guess what I'm asking is what rear LED red warning light are ya'll using with an aero post and XLAB cage? What fits around that cage or seat or seat post, to warn traffic behind you, not to KILL YOU.
