I've been thinking about a crabon smp used on evilbay...but my bike has a 27.0 seatpost bore, and can't be reamed.
I guess the SMP carbon won't work on bog standard old rails clamp types?
If you mean those saddle clamp that also clamp onto the seat pin, then no.
Those kind of saddle need a seat post that clamp top and bottom, not clamp sideway.
