The chain, made from hardened alloy steel, has chamfered shifting edges to increase shifting performance, and solid plates and pins to make it stronger. To access the fourth shift I needed to move my thumb more than was possible without rotating my wrist around the bar. It also required a lot of sustained strength. There’s tons of great party games — but unlike the rest, Box ONE is designed to challenge just ONE person: YOU! And you alone. Compatible with HG Freehub Bodies. Compatible with Standard Derailleur Hangers (Non Direct-Mount). Compatible with most 10,11, & 12-speed wide / narrow chain rings. Prime 9 chain must be used.

The factory setting for the derailleur’s clutch is stiff, which means its initial movement has a significant resistance peak before the cage is able to smoothly pivot forwards. General operation was quiet, too, and shifting under power was good – as long as the shift lever was pushed far and hard enough. Reducing tension on the adjustable clutch did lighten upshifting but increased the amount of chain slap and reduced overall chain stability, making the adjustment to a lighter setting a compromise not worth making. Because the derailleur’s cable stop is positioned vertically (similar to Shimano) a large loop of cable is required to avoid a sharp bend that could reduce shifting performance. Compared to SLX M7100 (1,221g), XT M8100 (1,153g), XTR M9100 (996g), and GX Eagle (1,163g) it is significantly heavier.membership required; continues until cancelled. Game catalogue varies over time; see xbox.com/game-pass. Online multiplayer requires Game Pass Ultimate or Core (membership sold separately). Weight-wise, the full 1,375g Box One Prime 9 setup I’ve reviewed is roughly equivalent to SRAM NX Eagle’s 1,362g weight and Shimano Deore M6100’s 1,330g. The clutch interferes with the derailleur’s ability to easily move into lower gears because of the mechanical coupling between the shifter and derailleur via the gear cable, leading to heavy shifter paddle operation. However, general shifting was good and with a positive push of the lever (more on this below) the derailleur didn’t miss any shifts and wasn’t hesitant in its operation. It also happily shifted gears under power. The clutch wasn’t able to stop the chain from skipping down the cassette when freewheeling. Alex Evans

Compared to Shimano, pricing for Box One Prime 9’s derailleur and shifter sits in a middle ground between XT and XTR, while the cassette price is similar to Shimano’s SLX-level.

Some apps require app provider-specific subscriptions and/or other requirements. See www.xbox.com/live. The finish on the chain and cassette have shown little signs of wear during the test period and the teeth haven’t become hooked or the chain links stretched. The maximum jump between gears is eight teeth (consistently between the lowest three gears), with the jumps decreasing as the gears become higher. The consistency of the gaps makes adjusting cadence to a gear change more gradual.
