100% CNC-machined, these outer chainrings are available in various sizes and for cranks (5 spider) with 110 or 130 BCD.
This TA X145 50 tooth outer chainring is compatible with 2015 Campagnolo 11 speed 4-arm chainset such as Super Record, Record and Chorus. Made from heat treated 7075 alloy, they are anodised Anthracite in colour and feature lazer engraved decals.
The teeth are cut in the traditional manner on a lathe which produces a much better and more accurate tooth form than pressing which is used by most chainring manufacturers.
Smooth Drivetrain Performance This Shimano XT 11 speed chainring features Dynamic Chain Engagement technology, which uses a unique tooth profile that provides superior chain retention, drivetrain smoothness and less chain noise. This updated version of the XT chainring includes a narrow-wide tooth profile for even better chain engagement and makes it the perfect chainring to suit any rider, in any condition. Technologies: Dynamic Chain Engagement: This technology effectively holds the chain and prevents chain drop. This is achieved by using a broader and taller tooth profile in conjunction with a special hooked leading edge. This all aids drivetrain performance on uneven terrain, keeps chain noise low, drag to a minimum and increases chain and chainring durability.
The radical new look and feel of the SRAM X SYNC Eagle direct mount chainring is a result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNC chainrings. It subjected every size of chainring to untold environmental and mechanical tortures, abuse and neglect, in both lab and real-world settings, to come up with a chainring that would augment the Eagle drivetrain's performance in all conditions. The longer, positive-rake tooth shape has been designed to work perfectly with the Eagle chain to increase chain retention and overall pedalling efficiency, while decreasing friction, noise and wear. Technologies: X-Sync 2: X-SYNC 2 Eagle is the next evolution of SRAM X-SYNC technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC Eagle design reduces friction and the accumulation of mud, grit and grime.
Like Ceramic Hybrid, Zero Ceramic use a combination of ceramic (Silicon Nitride - Si3n4) balls and steel races, except they are of higher Grade 3 quality. The races are also black oxide treated and ground to a mirror finish which prevents corrosion and provides near perfect efficiency and tolerances.Key Features: Bearing Code: 6805, Dimensions: 25 x 37 x 7mm, ABEC: 5, Grade: 3, Seals: VV, Grease: Kyodo Yushi PS-2, Application: Hubs, Bottom Brackets, Weight: 18.74g.
