SRAM's new 11-speed road drivetrain should be hitting the markets around mid-to-late June for the SRAM Red 22 and into July for the SRAM Force 22. After introducing the XX1 drivetrain at iBike last year, you knew an 11-speed road gruppo would be around the corner soon. With the new groups come some pretty slick upgrades and tech advances.
Chain: What can be improved about a chain? Well, according to SRAM, the new Red 22 chain features more heavily chamfered outer plates for improved shifting and quieter running to help steer away from that "clunky" shift of the past. Other advancements include a new inner plate finish plus chrome hardened pin construction, which both aid in longer chain life. The HollowPin construction provides smooth, precise shifting and weight savings without sacrificing strength.
Cassette: The new 11-speed cassette is exactly what you would expect: light, strong and efficient. Coupled with the new chain, the PowerGlide cassettes are designed for high shifting performance with a quieter chain/cassette combination and longer life.
Cranks: There are a TON of new crank options, including cranksets that will work together with front derailleurs that self trim and adjust (yaw control) to prevent chain rub on either the inside or outside of the front derailleur cage. Also, are the Quarq cranks which are unmatched in providing training feedback from the integrated Power Meter while still maintaining a sleek geometry, reduced weight and clearance for oversized frames and aerodynamic chainrings. Whether you choose any of the three crank designs, you'll find a wide array of crank arm lengths, gearing, and bottom bracket interface that you need.
