EXCELLENT.That’s a fair thing to point out. I’ve added a warning.
And to add to the warning don’t do this at home, and don’t do this with even a steel seatpost which has a narrower wall thickness then an alloy seatpost. NEVER EVER EVEN THINK about doing this to carbon fiber or titanium, you will get hurt and it’ll suck.
If you are going to ignore the above warning or ask a professional to do this you want to start with something like the above a forged Aluminum seatpost, don’t do it with a cnc’d seatpost like a Thomson. I’ve seen folks drill out a Thomson stem to route canti cables, and the stems crack.
Very fair warning now; all those points are spot-on.
That Sim Works (by Nitto, forged) post is probably one of the few posts that can take this drilling, and even then only done as carefully and precisely by experts as Alexidb has now explained above.
Completely agree: NEVER do this on c-f, ti, or CNC alu components; those parts are already very highly engineered to reduce weight (some even have rider weight limits), etc., and the risk of causing structural failure by modding them is simply not worth it.
Thank you very much for the understanding and for the consideration of others who may not have (especially on this non-cycling-specific forum) the same experience that you clearly have.
Cheers and best regards.
