The XX1 was built with a dedicated 1x drivetrain philosophy -- making it simpler, lighter and more durable than any other. Better known as the King of the Ring, the XX1 was developed for maximum chain control.
The GXP bottom bracket delivers a more narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.
Please Note: GXP bottom bracket and chainring are not included.
I am running these cranks on a 1x10 setup with no chain guide on very rocky mountain terrain. Shifts super smooth and great chain retention. Highly recommend these!
I've been running a 1x setup for a number of years and was excited about the possibility of dropping my chain guide and trying these cranks out instead. I bought these wondering if I could really make them work on my 1x setup. I was amazed to find that I NEVER dropped a chain! I mean NEVER! This chainring works better than my old 1x setup with the chain guide. I've used this for a number of months in all kinds of conditions (fast flowy trails, rooty technical trails, jumps, mud, dry, you name it) and never had a single problem. I'm running a non clutch style derailleur and everything works fine. I would recommend them to a friend with no reservations at all.
I own two of these, one for use on a 1x10 drivetrain and one on a SS. Both perform flawless. It can be used without the other expensive XX1 components. Matched with any of the XX1 chainrings, a good type 2 derailleur, and a 10-speed cassette, it operates smooth and quiet. No need for a chain guide either.
