Box Four 8 Speed Wide Range Groupset - Multi Shift - 11-42T - 8 Speed YGroup_7033473564717 CO2 inflatorThe Box Four range is for those people who just want less fuss! You're fond of Prime 9, but know 8 is enough, and surely 12 42T is plenty of range for an 8 speed cassette. The Box Four derailleur still has the Limited Slip clutch but now arrives with a more compact cage. The custom 8 speed chain is built for abuse, although it's sophisticated enough to have its own wide narrow chainring. Who's this item for: The multishift option is perfect for riders
