Sram Force 22 Bb30 Yaw

The new Force 22 crankset delivers an upgrade in performance by utilizing unidirectional carbon in the crank arm matched to a forged alloy spider. And, like RED, the hidden bolt pattern makes better use of carbon fiber to further improve stiffness and shed weight. The stunning X-GlideR chainrings are optimized for use with the Yaw™ Technology in the front derailleur, delivering seamless, flawless performance. It comes in fullsize and compact ratios and in multiple crank arm lengths.Features:- Hidden bolt pattern leverages the characteristics of carbon fiber while presenting a sleek appearance.- Stiffer X-GlideR chainrings feature thicker construction, advanced shift timing pins and ramps, which are optimized for shifting with the Yaw™ front derailleur.Specifications:- Arm Material: Carbon, Machined alloy spider- Chainring Material: Machined alloy- Weight: 697g (BB30 172.5mm 53x39 BB not included)- Compatibility: SRAM RED® 22 & Force 22 Yaw™ Front Derailleurs, SRAM RED® 22 & PC1170 chains- Technology Highlight(s): Carbon Fiber Arms/ X-GlideR chanirings/ Hidden bolt configurationTechnology:X-GlideR Chainrings:The chainrings are designed for an optimized shifting performance with the Yaw front derailleur. The stiffer rings (5mm 7075-T6 aluminum CNC-machined) feature upshift rivets with an advanced design adopted from SRAM XX. CNC machining allows for precision control of each tooth shape, ramp, and nearly every shifting feature of the chainring. Chainrings, chain, and front derailleur are designed as a single integrated system for optimized performance.
