Can you even find any? I see SJS in UK sold out of their inventory.. Many months ago..
now Nada/Zip.

the Kalloy ones and, similar ones Nashbar, etc. are $20, then you sort out the stem
to reposition them .. higher and closer

I have a couple ITM trekking bars, that is my set up.. higher [than the saddle] and closer..
so my most comfortable reach is the sides of the figure 8 bend.. flat, open, palmed ..
on thick double padded wrap.
