SEAT PIN
Ok, so this frame uses a 26.6mm dia seat pin/post
Contrary to what the internet says a Trek Multitrek CroMoly 700 from 1993 (or 1992/4) uses a 26.6mm
Not 26.8
Not 27.0
Not 27.2
I don't have pictures before, but I had a seat pin that, I thought fitted, but after I pushed it more than 1" into the seat tube, it jammed.
I was under time pressure at this stage, and resorted to my neighbour opposite who worked his magic, and turned my - uneven diameter seat pin, into a beautiful 26.6mm. Lathing it down from 26.8mm, the walls are 2.8mm thick, and it's not that long, so this will be fine.
The un-lathed end that fitted fine:
That'll do
I was so relieved to get this sorted:
It fitted 'perfectly'
Will it slide down - Yes
Time for a test ride by my Father:
You can see in this picture the bars give a very upright position - this is to mimic the existing upright position my friend gets with dutch style swept back bars. The benefit of these 'magix' butterfly style bars is that you get other hand positions to help on longer rides, which are most noticable when going up hill, or down hill fast. According to the reading I did. I also set the brakes up, so you can just reach the lever with finger tips, when hand is on the outer edge of the bars.
