t7 handle on bedford 29 : which 22.2 seatpost?

I’m considering a T7 handle for my Bedford 29. Seatpost diameter is 22.2mm (same as a Coker). Which rail type seatpost is appropriate? I was reading some threads indicating that the Primo ROD was a tight fit on some frames. Is there a readily available and appropriate alternative?

Thanks,
Tom

Primo worked well on my Bedford 29 when I was setting it up with the T7. I didn’t see a need for an alternative.
