Dream Bike Build

I've used it several times

Lover the shifting, very quick and responsive. Shifts great under a load in a panic situation.

GX is great

I've put it through the wringer

Been running X01 and my new bike has GX. Love it just as much. I am not super picking about my shifting... I'm not sure I notice any difference. I think you lose a couple of ounces going to GX from X01, other than that GX is a solid option.

crisp clean smooth

Is the GX as good as X01.... I don't really know, i've been running X01 for the last year + and have a hard time finding a big difference. if you want to save a few bucks this is one way to go. Most will be totally fine with performance. Quality is excellent and is very durable.
