I have recently acquired a frame from a bike shop who were having a bit of a clearout. The frame is identical to the one in this photograph:
I need to find out what seatpost size to use. I have no idea what year the frame is so cant search on Trek's website. I measured it and it appears to be 28.6mm.
If anyone knows the size or has the same frame please could you advise what size seatpost I need.
