high gear on a 10 speed is the biggest and smallest sprocket together ;)

I don't get it
Where's the advantage?
The middle sprocket is just replacing the chain
It's still a one gear bike , always in the 10th gear position

2 big sprockets give it the torque
think of an old ford flathead v-8
no horsepower but could pull a house because of the torque

[really_troubled]

if the 2 big gears are identical then it's a 1:1 ratio, so there would be no advantage

if anything, added friction from another bearing and the possibility that the teeth aren't perfectly matched, it's possible that you will lose output torque or speed

Edit:

you might want to put a guard on the bottom though ... if anything gets caught in between you are going to be in for a rude awakening ...

There's no extra torque added with that setup.As TLG & _troubled pointed out, the large middle sprocket just replaces the chain because it's 1:1 ratio with the front drive sprocket.Final ratio (without counting sprocket teeth)looks like top gear or so on a 18 speed..No added mechanical advantage, but advantages to losing the chain.

No low end no power just speed

the 2 big sprockets are not the same size

[really_troubled]

it's a little hard to tell, but the middle sprocket looks slightly smaller

but it would need to be larger than the driven sprocket to increase the output torque

the driven sprocket is the biggest sprocket, so no increase in torque

you're confusing speed (rpm) with torque

[The Noof]

I think it's perspective.Only way to be sure is count the teeth.In any case, if the middle one is smaller,mechanical advantage is reduced, not gained.
