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.

The maximum jump between gears is eight teeth (consistently between the lowest three gears), with the jumps decreasing as the gears become higher. The main pitfall of Box One Prime 9’s drivetrain is its dominatingly heavy shift operation caused by its stiff and slightly sticky clutch. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. I fitted the Box One Prime 9 to two different bikes – my Yeti SB165 long-term test bike and Marin Alpine Trail XR – and compared it back-to-back with a host of other drivetrains from SRAM, Shimano and other brands. Take on awe-inspiring weather events like towering dust storms and intense tropical storms as Mexico’s unique, dynamic seasons change the world every week.

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. With only nine gears, the spacing between each sprocket is larger than 10-, 11- and 12-speed offerings, which should improve shifting performance because derailleur indexing and cable tension don’t need to be as precise due to each shifting movement being larger. Box ONE is an ever-evolving game of trivia, codes, puzzles, and discovery - only from the mind of Neil Patrick Harris. As such, the Box One Prime 9 system has been designed with durability and shifting performance in mind, and although it only has nine gears, it still shares its wide-ratio cassette range with other brands’ 12-speed offerings.

The chain, made from hardened alloy steel, has chamfered shifting edges to increase shifting performance, and solid plates and pins to make it stronger. The lever has a lot of travel before a shift is engaged, too, so a fair amount of sustained force was required to change each gear, which didn’t feel particularly natural. Alex is also a dedicated eMTB rider, and still dabbles in racing of a sort, doing his best to top the Strava leaderboard on the steepest, gnarliest and twistiest trails the Tweed Valley has to offer – just for fun, of course.

However, it states its system isn’t compatible with 12-speed chainrings or non-narrow-wide offerings. Like the SRAM systems, Box’s reliability might be better in the long run, but its performance is so compromised it’s hard to vouch for it. But selected titles are optimised to take advantage of the power of Xbox One X with higher resolutions, faster framerates, improved textures and more. Winding down clutch resistance improved shift feel but further impacted already compromised chain stability.

The cable clamp and cable stop don’t line up perfectly when the derailleur is in the highest few gears and the cable contacts the derailleur’s body. The cassette’s lockring appeared to be quite fragile and its splines had some visible scoring after one use with a cassette tool, so care should be taken when fitting and removing the cassette to avoid stripping the splines.

Although the derailleur’s limit screws and b-tension were easy to set, indexing the gears was much harder than I was expecting.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. To help reduce this problem, left and right adjustment on the lever clamp could help, as seen on SRAM and Shimano offerings.
