Features: Chainset
- New 4-arm design for same stiffness with lighter weight. Hollow outer chainring increases stiffness by a massive 20%. Shifters – Dual Control levers on the base bars & satellite controls on aero extensions allow for multi position shifting. Brake Levers – 7900 aero brake levers with lightweight carbon lever construction. Aero Brakeset
- new symmetrical dual pivot design & twin bearings reducing pivot friction & improving efficiency & controllability Rear Derailleur
- shifting effort is now more even across the range with similar force required at both ends of the cassette. Front Derailleur – revised actuation ratio results in a shorter stroke at the lever & reduced effort Chain – now symmetrical to run either way with a PTFE coating for smooth shifts. Cassette – titanium large cogs & carbon carriers for smaller cogs keeping weight to an absolute minimum. BB – smaller bearings make the new SM-BB9000 lighter than ever before.
