Limited Exclusive Edition Box One Presented by Neil Patrick Harris Game

Product Information

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. 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.

My test sample wasn’t supplied with an I-Spec or Matchmaker adaptor, although these are available. Alex Evans

For You Alone

You don't have permission to access "http://www.argos.co.uk/browse/technology/video-games-and-consoles/xbox-one/c:29994/" on this server. 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. From a pricing perspective, Box Components Box One Prime 9 drivetrain is comparable to SRAM’s GX Eagle level (once you’ve removed the cranks and chainring from the GX groupset). 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.

The Box One Prime 9 drivetrain might last longer than SRAM’s offerings – thanks to the chunkier chain and cassette – but I don’t think you’d be able to live with the high-resistance shifter lever once you’ve experienced a lighter system. The cassette uses Shimano’s Hyper Glide (HG) freehub body which is different to SRAM’s XD Driver and Shimano’s Micro Spline system.

The cable-pull lever can shift four gears at once if pushed far enough, but accessing the last shift is virtually impossible while riding because of the amount of travel required to engage the gear.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. Box Components Box One Prime 9 drivetrain compared to SRAM NX Eagle, SRAM GX Eagle and Shimano SLX, XT and XTR Installation was relatively straightforward and I was particularly thankful for the shifter’s hinged bar clamp, which meant I didn’t need to remove the grips or brake lever from the bar to install it. When lower gears were selected and chain length grew, the derailleur’s clutch tension caused the cage to be stiff pivoting forwards, so the cable-pull shifter lever was heavy throughout the lever’s throw.
