Seatpost suitable for quill modification?
Posted: Mon Nov 26, 2012 12:09 am
Hi,
I'm currently riding a Moser Leader AX from '93 and it has a somewhat unusual seatpost solution. Instead of a cut in the frame and a clamp, it requires a quill seatpost. Now these are somewhat rare and when they crop up they're expensive and heavy.
So it's wintertime and I need something to keep me from going nuts from lack of riding. So I thought I'd make a lightweight quill seatpost!
Now the only problem has been finding suitable starting material.
There are essentially two solutions (and a non solution) out there today:
#1: The Campagnolo solution, with a diagonal screw pulling the quill assembly upwards. Incidentally pictured with the same frame as I have, though in a different colourscheme.
#2: The solution on my current seatpost (not mine pictured), which is a bit finicky, since I have to remove the saddle to remove/adjust the seatpost.
#3: Actually just found this one, but would be even weirder and require a reaaaallly long allen key. I assume this is for a bmx or similar.
Despite its drawbacks, for ease of manufacture, I was planning to go with #2. I could even use the assembly on my current seatpost (which is in bad condition and hovering around the 350g mark for 170mm).
Ideas? Thoughts? It's hard to find pictures of seatpost taken from the top without cradle assemblies and collectively (and probably individually) you've seen a lot more seatposts than I have.
Any input greatly appreciated. In terms of styles, zero to little setback would be preferable and material I'm not sure yet. Carbon would be really nice, if there's a good way to do the conversion.
