After a few days Sandro phoned me, and tried to convince me that knees wouldn't touch.
I was very sceptical (Reg's references to John Wayne etc.)
Anyway we agreed I would pay for the bags and if not satisfied he would refund me in full'.
They arrived yesterday...
Put them on the bike this morning with :
Right hand pocket:
PHD sleeping bag containing liner, long johns, woolly socks
left hand pocket:
MLDesigns Trailstar + inner
Blue pocket:
Neoair sleeping mat, Klymit Cush pillow, Permavent sheet, Alpkit KLoke bivvy bag
Difficult getting it in, and it was very bulky... I was definitely losing hope...
Moved them up a bit nearer the stem, and went up the street.... very surprised that my knees were almost clear, mainly clear.
Came back and adjust my seat a bit (5 mm)
Up the street again.... very good, excellent..
Put my frame bag on (without taking the bags off), containing my usual haul:
First aid, tool kit, pump. zip ties, spare tube, tiny lock, MSR Trailshot, duct tape, tubeless repair, tent pegs, 500 ml water...)
So I got my gear on and went out for my regular 7 mile ride (800 feet, some gnarly climbs too, a bit of mud)
THE RESULT: Excellent !
I didn't know it was on. Absolutely no movement. The bike handled certainly better than with a handle bar bag on, not that I find a handlebar bag much of an encumbrance)
I even simulated lifting over a gate, no problem as your fork crown is there staring at you and none of the bag anywhere near..
Here are some pics:








It's very lightweight material, so you wouldn't want anything sharp or pointy in there. I think Sandro claims it's waterproof (but that might be Italian or French waterproof)
So my sleeping bag is in a dry bag.
You can see it all looks bulky, but it doesn't interfere with your riding at all. And no movement.
As for me I'm on a medium bike, and between 5'8 and 5'9, don't have particularly short legs, nor particularly long.
I'm impressed.

I definitely thought this morning they would be going back !!
