Just got back from my ride, managed 20 mph on a long flat at 75 rpm's.. still had 2 gears left on the rear. The chain stays in line on the big ring & last 4 on the cassette, like wise, it stays right around the middle of the cassette & middle chain ring when doing about 14 mph (my normal). This is the first time I really got to air it out because of the rain. Soon as I heard that click from my left shifter, (IT WAS ON THE BIG RING) its really close to shifting like the rear. But that was what that SLX crank was made for. It has took sometime to dial the FX in, but it is so smooth riding.. those 32's plus carbon fork, iso/zone bars, grips, SSR saddle, Monostay rear damper. like riding with suspension. All under 23 pounds.. Sorry for the long read, but it is really awesome.
