Rat Bikes! Pub Bikes Beaters! Frankenbikes!

I think a longer stem will counteract the ride a little. As your stem gets longer, you create less and less turning force when you lean on the bars, with a single hand say. I think. Will try it anyway, as soon as a cheap stem pops up in my Ebay search.

Longer stem feel slower to turn but doesn't necessary mean it is slower.
