    Don't waste anything.

    Oval chainrings aren't exactly popular, but you can see the appeal. Designed to prolong your "power zone" and reduce deadspots, rings like the Rotor QX1 might look a little strange, but they work. Rotor designed the QX1 to run with SRAM, Specialized, and Rotor one-by drivetrains, and gave it multiple mounting holes so you can adjust the orientation of the ring to suit your style. The thick-and-thin tooth profile locks the chain on to prevent drops, and the aluminum construction is lightweight but bomber, so you can ride it for years.

    • Slightly oval shape
    • Thick-thin tooth profile
    • Compatible with SRAM XX1 (adaptor required), Specialized, Rotor REX 1.1, 2.1


    • Familiarity: I've put it through the wringer

    I'm loving the QX1 chainring paired with my SRAM XX1. Chain retention and durability has been flawless, yet I'm eeking out a few extra watts by virtue of its elliptical shape. I've just proactively replaced my chainring after 3k miles.

    And no, you won't notice the elliptical shape after a couple rides!

    Excellent performance, so so fit

    • Familiarity: I've put it through the wringer

    Running a 32T QX1 on Giant Trance Advanced SX. Ring works really well for my pedal stroke. I tend to lose power coming to the top of the pedal stroke and this seems to smooth it out. It just feels better everywhere and I can hold onto the gear longer before I have to downshift. My only issue is that the spider you have to replace on the SRAM X01 (GXP) crank moved the chain line out another 6mm over stock! This made for a noisy 3 low gears and a nasty looking chain line in those gears. I ended up swapping the ring to the inside of the spider to bring the chain line back to stock. Works, but when you buy a premium product at a premium price, I expect it to fit perfect out of the box!

    Rotor are releasing a GXP specific spider, if you use the BB30 one then the chainline wont be ideal.
