Semcycle upgrade to Miyata seat?

I have a Semcycle XL with a Semcycle seat. I am thinking of upgrading
to a Miyata seat (should have snagged a Miyata seat while I was down
at the UNICON earlier this week… sigh, missed opportunities… ;-(
oh well what can ya’ do?! ).

Anyways, just wondering if the Miyata seat, with seat post included,
will fit on the Sem, anyone know?

thanks in advance,
Erin

That is what I currently use. I have noticed that when the seat poste clamp is tightened all of the way that the seat will still rotate under stressfull riding conditions. I think this is true with the origional seat as well. I am not sure since I bought the Miyata seat at the same time as the 24" Semcycle XL.
