Box Components Two P9 X-Wide Single Shift E-Bike Groupset

Our Box Two tier's mission in life is to deliver performance similar to the Box One but without its exotic (and costly) features. You still get the Tri-Pack™ Clutch in our derailleur only it isn't adjustable. The cassette's 11-50T range is equally impressive but we don't cut it out of a single block of steel. The action on the shifter is just as snappy although you don't get the rigid die-cast pull lever. The chain boasts the same unique ability to mate with a wide/narrow chainring except you give up the trick DLC top coat. You're hardly shortchanging yourself with Box Two.

Box Components One Prime 9 Chain

The Box One chain is protected by a dual-coating. Starting with a Nickel plating which aids in corrosion resistance and then top it off with the "Diamond-Like Carbon" layer. The DLC is as fancy as it sounds; a synthetic diamond nano-coating that turns up the volume on hardness, wear resistance, and slickness. All Prime 9 chains have chamfered shifting edges, solid plates and solid pins to safeguard durability. Our unique inner link spacing is engineered to grab those modern wide/narrow chainrings. Box has chosen to modernise the 9-speed platform due to the chain's spirited reputation.

Surly Cassette Cogs

Shimano compatible Spline fitting.9 Speed spaced, these cogs can be run 9speed or less, together with Shimano 9Spd gear shifter systems. Note: Teeth profiles are straight forward, making them ideal for Single Speed applications, however, with no twists or ramps etc, the gear shifting will not be as slick as with regular Shimano cogs when used in a multiple cog line-up.The large foot print caused by built-in spacing at the base of these machined cogs gives a larger foothold on the cassette body, making these a premium selection for Single Speed or multi-speed use with reduced risk of torque transfer damage to the cassette hub body. (Note: This point is especially important with Alloy or Ti Cassette bodies.)
