So i ended up snapping my dawes impulse and have replaced it with a peugeot monaco frameset, the frame didnt come with a seatpost and Im currently struggling to find any information or specs about these frames.
Took it to my LBS where they were a bit useless but I least found out its less than 25.4mm which is the smallest they had and after researching Sheldon Brown I havnt found much either so I think it may be either 24mm or 25mm. Does anyone have any better info on these frames or know where I could pick up such a seatpost size? Any advice is greatly appreciated to get me back on the road
Here is a picture from the ebay listing:
