Just took delivery of Dual frame, 56cm, ca. 2004 (before they introduced HF) and in process of building it up. Bit confused about correct seatpost size; have heard 32.4mm, 30.6mm, and the seat clamp says 35.6 on it!

Have heard Deda Blackstick is a good fit, what size should I run?

Thanks

And the answer is... *a 56cmDual takes a 32.4mm post* and the 32.4 Deda Blackstick fits like it was tailor made. Photos of complete bike to be posted soon :)

My humble apologies to those who may have read the title of my original post and opened it thinking I was presenting and answer (and hoping for one!) not asking a question... judging by the no. of post readers vs answerers (none till now) there may have been a few of you... sorry :D
