What are the main differences between Package 1/2/3/4/5/6?

REAR DERAILLEUR

– X-SYNC pulleys for increased durability and efficiency

Sram Force eTap AXS
– Orbit chain management technology keeps the drivetrain quiet and secure

Sram RED eTap AXS
– Orbit chain management technology keeps the drivetrain quiet and secure

CASSETTE SPROCKET
SHIMANO Ultegra/Dura-Ace
The Dura-Ace cassette is lighter than Shimano Ultegra cassette because the cogs are made of titanium and steel and the Ultegra cogs are made from steel.

What is the benefit of upgrading to wireless system (12s)?
– Wireless Shifting
It’s clean, secure and reliable technology to match your modern bicycle. eTap wireless shift logic is simple and intuitive to ride: one button to go easier, one to go harder.
