To keep your Avid brakes functioning properly, check your pads for wear and replace them when necessary. Organic compound pads are softer for quieter braking and increased modulation, while metallic pads dissipate heat better and last a bit longer. Two pads, one retraction spring and a mounting bolt are included (enough for one brake) in each pad set. And, choose an aluminum backing plate if you're really counting the grams.

The Box Two chain's nickel plating adds both corrosion and wear resistance. All Prime 9 chains have chamfered shifting edges, solid plates, and solid pins to safeguard durability.

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 and steel variant. All Prime 9 shifters take advantage of the 9-speed's inherent durability, simplicity, and reliability. Not only is the shifter mechanism joyfully simplified, but fewer shifts are needed for every mile of travel. And the best part is? Prime 9 is also terribly forgiving so you won't have to constantly adjust your set-up. Available as a multi-shift (pull several gears at once) or single-shift shifter (a sound choice for e-bikes).

Designed to pair with Box's 11-speed mountain bike rear derailleurs, the Box Two Twin Lever 11-Speed Shifter has some pretty sweet ergonomics with its dedicated thumb and index finger controls. This new twin lever design is a slightly different design from other brands lever offerings and should help prevent miss shifts and provide precise and reliable gear changes both up and down the cassette. One of our favorite features of the Box Two Twin Lever is its ability to downshift up to four gears at a time so you can roll into a climb with speed and quickly grab the gears you need so you can easily make it to the top. Its aluminum and glass fiber with nylon composite construction keeps things nice, light, and durable while keeping its cost low. It includes a smooth stainless steel cable so you can get it bolted up to the bars and hit the trail.

The Box Four cassette adapts our Prime 9 philosophy of durability, simplicity, and reliability at a great price point. All cogs are stamped from steel, given our durable black coating and then the larger cogs are pinned to each other with spacers for easy installation.

Our Box Four tier is for those people who just want less fuss! You're fond of Prime 9, but know 8 is enough, and surely 11-42T is plenty of range for an 8-speed cassette. Our derailleur still has the Limited Slip clutch but now arrives with a more compact cage. The custom 8-speed chain is built for abuse, although it's sophisticated enough to have its own Wide/narrow chainring. Push through fewer gears with a no-nonsense shifter. This combo will transport you to 1 by territory for less than $200.
