The latest iteration of Race Face's Turbine series chainrings carry over all the features of the previous models, but with added 11-speed compatibility. Each double chainring set is machined from durable 7075 aluminum and intricately machined in a way that reduces overall weight without sacrificing stiffness. The outer chainrings feature and aggressive design with machined ramps, steel pins, and individually profiled teeth for shift response that is predictably quick and quiet. Turbine rings have been extensively tested, and are approved for cross country, trail, and all mountain use. The 104/64 bolt pattern of these rings fits a wide variety of cranksets from various manufacturers.
