I thought that, but if I’m carrying luggage I usually raise the bars up anyway as I find adding a few KG’s to the bike gives it a tendency to stall if the front wheel bumps into something, so raising the bars 2″ pushes my weight up/back and restores the front wheels tendancy to lift.
OTOH you could probably get a dynamo light under it (on a rigid bike or the road) if you wanted too it’s that high.
And it’s better than my DIY version (essentially the same, but padded with an old sleeping mat foam so much softer) which wouldn’t quite clear the front wheel at full compression.
The other advantage is being able to put a sleeping bag in a 13l or 20l bag, rather than a 7l (which it just about fits in), but then takes an hour or so of shivering to loft properly.
Trying to avoid sounding like I’m justifying it now that I’ve paid for it.
