Hello,
I'm looking for some advice.
I have a Dahon Jetstream P8.
The seatpost appears to be around 34mm in diameter.
However it is shimmed. I weight around 105kg, and the shim is focussig the stress on the seatube.
I can see some tiny cracks appearing around the circular hole at the end of the seatube clamp slot.
I've measure the seatube internal diameter, it appears to be around 36mm ?
I've verified that a 34.9mm seat tube is very loose, so too small.
Can anyone advise the correct seat tube diameter for this model of Dahon ?
Photo attached.
Many Thanks.
