The Box Two groupset delivers similar performance to the top-tier Box One without the costly features. You still get the Tri-Pack (TM) Clutch in the rear mech only it isn't adjustable. The cassette's 11-50T range is equally impressive & the action on the shifter is just as snappy although you don't get the rigid die-cast pull lever. Completing this groupset is its high-quality chain, which boasts impressive torque power & speed as you explore the trails on your mountain bike. Box Two Prime 9 Shifter The Box Two shifter is the only shifter on the market (other than our Box One) that comes factory stock with a hinged clamp. Box Two is our performance tier so this shifter still maintains the durable cast aluminum top shell but trades out the Box One's 1-piece pull-lever for a 2-piece resin & steel variant. All Prime 9 shifters take advantage of the 9-speed's inherent durability, simplicity, & reliability. Not only is the shifter mechanism joyfully simplified, but fewer shifts are needed for every mile of travel. & the best part is? Prime 9 is also terribly forgiving so you won't have to constantly adjust your set-up.

Originally conceived as an E-MTB product to deliver long service life & extra range over fewer gears, we quickly grew to enjoy its abilities on unpowered MTBs. All cogs are stamped from steel & subsequently, the larger ones are pinned to alloy spiders. Due to its provenance, this is, without doubt, the most durable cassette in the range.
