Prime 9 Technology is a counter-intuitive philosophy based on the less is more theory. It embraces range without adding complexity. The outcome is fewer parts, reduced weight, and increased durability.
Our Box One tier is for those of you who just aren't satisfied with anything but the BEST! You like to get up there where the air is thin and the details matter. Every single cog on the 11-50T cassette is steel, yet it barely tips the scale at 360 grams; along with the chain, its surface is Dual-coated with DLC + Nickel and is both beautiful and durable. Your thumb will push a textured die-cast lever on a shifter that's had its hinged clamp whittled away by our CNC machines. Let's finish this package off with a derailleur that flaunts a Fully Adjustable Tri-Pack™ Clutch and super smooth sealed bearing pulleys. Pamper yourself a little; you know you deserve it.
