Have you thought about taking a hacksaw to it? It worked for me.

Hi -

I've got a Minoura Spacegrip mounted horizontally on the front
derailleur post on the trike (it ju-u-ust fits between the cranks).

I can't fit it vertically, because there's no way to change its angle
relative to the post, which is tilted backwards at, oh, 45 degrees or
so. My question for the panel is, can the Topeak BarXtender be mounted
on an angled post such that the extension ends up vertical? From
Topeak's website it looks as if it ought to, but I'd rather be sure
before I pay Wiggle my hard-earned.

I've got a Minoura Swing Grip on the tourer and that is adjustable as
I think you want your Spacegrip to be. Depending on how you put it
together, it'll angle towards or away from you.

Or a pipe bender to give a vertical pipe if that is the preferred
arrangement.

Are you certain? I've always been *terrible* at spatial ability,
especially the rotating/reflecting stuff I had to do when I used to take
IQ tests, but it doesn't look as if it will. Rather than my iffy verbal
ability, here's some bad ASCII art: -

This is a side elevation of the front der post \#\ on the trike: the
Minoura I have is attached to it and sticking forward at a right angle
[erm, subject to the limitations of ASCII art]; the bar extension itself
is horizontal, so we just get an end view of the bar. (I've drawn a
little Cateye light on it.)

In the illustration above I've rotated the Spacegrip 90 degrees, such
that the bar extension is aligned vertically rather than horizontally,
and it necessarily ends up at the same angle as the front der post.

What I need is this: -

another side view, showing that the binding bit is still necessarily at
right angles to the front der post, but the bar extension bit is
perpendicular to the ground. The bog-standard Spacegrip won't do it,
and I don't *think* the Swing Grip will do it either; the Topeak looks
as if it might.

That's not the problem - it ju-u-ust fits, but it fits! - as do the
little Cateye lights on it at the moment. However, the Smart lights I'm
intending to fit won't. :-(

I _think_ it does. I'll check mine tonight when I get home. I meant to
this morning but forgot.

Looking at
<http://flickr.com/photos/timintheshed/306760122/in/set-72157594392872315/>

you can see one on my Vision. To get to what you want involves two
things: Rotate the base through 90 degrees and tilt, what is for me,
the cross tube.

Rotating the base can definately be done - it's a square peg in a
square hole, rather like the minoura.

IIRC the cross tube is held by a screw and serrated nut. The nut
matches serrations in the tube moulding to allow it to "click" through
different angles - rather like adjusting a saddle angle IYSWIM.
Anyway, as I say I'll check it out tonight.

Right, I've checked it out. It does. Not very good photo of the
evidence at <http://flickr.com/photos/timintheshed/310578807/>

The black fitting on bottom of the bar is my light mount. Note that
adjustment isn't stepless, so you might not get it exactly vertical.

Ahhh, that's exactly what I was hoping for. *Many* thanks for going to
the trouble, that's really helpful!
