Actually Scrub...the LX crankset is the same weight (within a few grams) of my Atlas and Hone cranksets AFAIK. I run a single 32t ring so ring weight is moot. I personally feel that my Hone crankset is a little more laterally stiff than the Raceface. Given the similar construction, the LX would be similarly stiffer than the Atlas.

Atlas is pretty tough fo sho...but I never noticed my inner guide ring rubbing my frame with the Hone. I had to actually take it down a mm with the RF's.
