Box Four 8 Speed Drivetrain Groupset

The Box Four groupset is designed for riders who want less fuss.

It features an 8 speed shifter and an 11-42T cassette, which offers a great range of gearing to meet the demands of your off-road adventures.

Designed for smooth performance, its rear mech uses a Limited Slip clutch in a compact cage. A final highlight is its custom 8 speed chain that's built for abuse. This makes it a great groupset for riders that want strong groupset without all the frills and at a wallet-friendly price.

Box Four 8 Speed Shifter The Box Four shifter's main features aren't strikingly different from Box Three's. The key difference is its 8-speed platform. We've chosen to modernize the 8-speed in much the same way we did the 9-speed for Prime 9.

Just like the Prime 9, the Box Four shifters take advantage of the "less is more" theme and exploit durability, simplicity, and reliability.

The chain is polished and then chemically treated to achieve corrosion resistance.

We engineered the inner link spacing to be a little tighter than other 8-speed chains and is optimized for use with our Box Four Wide/Narrow Chainring.
