I have a few hundred miles on mine now and I really like the front,the jury is still out on the rear tho'. I'm getting a little unusual slippage exiting corners. In the tires defense,I have also just re-sprung my bike front and rear so that could have something to do with it. I'm thinking about getting the BT002 RS tires from Bridgestone and ditching these. In case you don't know Cycle Sector has either the BT016s or BT002RSs for $239 shipped a set with a 180 rear and about $250 with 190/50 or 55 rear.
