Seat Post - 26.4mm x 300mm

[petethemeat]

Hello,

I have searched the forum but could not find a thread for this subject.
I own a 1978 Koga Miyata Road-Speed and need to find a longer seat post.
The original is an SR Custom.
After some research, I found that all older models have quite a short length.
Does anyone have recommendations for seat posts that suit this type and age of bike?
Thank you.

I'd probably get me one of these: XLC R07 Seatpost Ø26.4 x 350mm
