Whose logo is this?
 

Im going through my seatposts sizing and IDing them.
This one stumps me.
Does anyone recognize this logo?https://cimg3.ibsrv.net/gimg/bikefor...c78dbe10dd.jpg

Kalloy I believe.
Like Trans-X or Zoom, it's a subsidiary/brand of Hsin Lung, possibly the biggest stem/post producer in the world.

thanks. Kalloy seems to be correct. (see attached)
Biggest seatpost producer in the world, and yet they aren't even listed in Velobase.
thanks for helping sort that.

I'm guessing that VeloBase doesn't try to include parts that are considered to be generic (or of Chinese production?).

Considering who uses Velobase, the listings would seem to congregate around older and more brand-named (expensive) items.

I haven't looked myself, but would any other Hsin Lung items branded Zoom or Trans-X, etc. be listed?

agreed (that most Kalloy products are too new to merit inclusion in Velobase)
but there some to be some interesting (or at least old) Kalloy vintage styles that I thought would have merited at least a mention of the brand.
see attached.
though maybe this fluted style is just a modern reproduction meant to look vintage.

I don't know.
