The stutter comes from the way the brakes are actuated. From the picture on Javelin's site I see that the housing is held at the top of the head-tube. When you brake the fork flexes backwards causing the cable's tension to change. The brakes will be slightly released causing to fork to move again, re-tightening the brakes, pushing the fork backwards. This happens in quick succession thus the brake stutter. The way to cure it is to move the attachment of the cable-housing to the crown of the fork. There are front cable hangers that can be screwed to the hole where a side-pull brake would be attached.

There are rumors that the D7100 and a new 16-85 will come out this year. I placed an order for this camera and lens in March this year, and I haven't got it yet because Nikon can't deliver the current 16-85mm.

As this is, to me as an amateur, a VERY expensive camera and lens, I don't want to waste money if the new versions of these (camera and lens) comes out this year. If I wait, and the price is going to be high, I'm going to be angry at myself for wasting my time waiting for a too expensive product to come out.

How does the price of the Nikon products evolve over time? Is it like regular products, they start expensive and get cheaper by time, or do they have a fixed price all the time from start to end?
