Round Seatpost for rear light cable routing

[langereise]

Hi all,

I am looking for a round carbon seatpost (27.2mm) with either a lateral hole on the post or at the clamping area to guide through a dynamo cable to a rear light. Any ideas?

Many thanks

Hi
I have this post here.
It does not have a hole but I think I'd be ok with drilling a hole in the bracket. There would be enough of the bracket left to take the charge of the saddle.
The cradle would not work for carbon rails.
