The racer X is a bit more nimble since it has considerably shorter chainstays and is overeal steeper as far as the tube angle are concerned making it a very nimble bike. The blur is a more forgiving bike but not as quick handling in some aspects. Both are top notch bikes and as far as quality, durability and strengh the RX is a better bike. Personally though I consider the exogrid to be a terrible waste of money. Its about $3K for just the frame and really doesn't offer much over the standard Ti version which is $2K. Honestly I would recommend the aluminum version which is $1600. Titanium is nice for hardtails but its mainly a gimmick with FS bikes. Al is simply a better material for most FS applications.
