Spidering no-Q DM Round Chainring

When weight matters, going direct-mount makes an impact, and ROTOR's Spidering no-Q DM Round Chainring certainly fits the bill with its feathery stature, and rigidity that doesn't waiver under pressure. The engineers at ROTOR definitely put some serious consideration into the craftsmanship behind the DM Round Chainring, which is immediately apparent thanks to its stunning CNC machining, and single-piece construction. It features aeronautic-grade 7075 aluminum that's crafted in Spain to intensely tight tolerances to keep your shifts smooth and effortless. The Spidering no-Q DM Round Chainring is compatible with ROTOR's 2inPower DM, INpower DM, ALDHU and VEGAST cranksets, and is simple to mount with just a hex-wrench connection, skipping proprietary tools and opting for simplicity, so you can make tweaks and changes on the run without the headache.
