The BOX Four tier is the perfect choice for riders who just want less fuss! You're fond of Prime 9, but know 8 is enough, and surely 11-42T is plenty of range for an 8-speed cassette.

The 8-speed chain is built for abuse, although it's sophisticated enough to have its own wide/narrow chainring. Push through fewer gears with a no-nonsense shifter.
