What Our Gearhead(R) Experts Are Saying: "I swapped these onto an older 2x setup and the difference in shifting was immediate. It feels smooth and quiet even under load, and the durability has held up well through a full season of riding."We keep our cadence steady across rolling terrain and long climbs, and the Turbine 2X 104/64 BCD Chainring from Race Face helps every shift feel smooth and controlled. Whether we're spinning up fire roads or dropping into fast descents, it keeps transitions between gears quiet and predictable so we can focus on the ride ahead. Precision CNC-machined from 7075 aluminum, these chainrings balance lightweight performance with long-lasting durability. Sculpted teeth and mapped shift ramps work together to guide the chain cleanly between rings, improving shifting consistency across varied terrain. Designed for 11-speed drivetrains and compatible with 104/64 BCD 4-arm cranksets, it offers a reliable upgrade for riders keeping a 2x drivetrain running strong.
