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).

The Box Four Rear Derailleur is the base of Prime 9 Technology that offers an affordable clutch based 1 by 8-speed derailleur that is simple and light; this makes it a perfect candidate for every entry-level bike that traditionally has a 3 by drive-train that is neither durable nor user friendly.

The Box Three Rear Derailleur simplifies the features found on the Prime 9 Box One and Two rear derailleurs making for a fully featured wallet friendly rear derailleur. Including a Limited Slip Clutch, Sealed bearing pulleys and a solid construction Box Three Rear derailleurs are compatible with 11-46 and 11-50t derailleurs making it one of the most versatile derailleur offerings for Prime 9.

- Cold-forged, CNC-machined 6061-T6 aluminum with built-in return spring - Clamp integrates with ODI Lock-On grips - 50g

Box One Genius brake levers are the first ever to incorporate a clamp for ODI Lock-On grips. This ensures that your grips stay put while eliminating the need for an extra clamp. At roughly 50 grams, these cold-forged and CNC-machined levers beat any other on the market. Genius levers have a built-in return spring and are fully compatible with carbon handlebars. The Mid reach lever features a new design that puts it in the same reach position as the Long, but with a more BMX-specific blade for better one-finger leverage. Other features include adjustable reach, a titanium mounting bolt, and stainless steel hardware. Genius levers are designed to work with linear-pull brakes. They are excellent for BMX, mountain, city, urban, and tandem flat-bar bicycles.

The Box One multi shifter is the only shifter on the market that comes factory stock with a hinged (and machined) clamp. It's top of the line and comes packed with other features such as a durable cast aluminum pull lever and top shell. 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?

The Box Three Prime 9 cassette is a great all-around cassette option. All cogs are stamped from steel and subsequently, the larger ones are pinned to alloy spiders. It also features weight-reducing holes on the cogs. - The Box Three Prime 9 offers ultra-wide ratio with consistent progressions - Prime 9 technology offers the same range as a 12-speed drivetrain, with fewer gears to shift through - Fewer parts, reduced weight, and increased durability - Cogs pinned to lightweight spiders - Constructed using a standard freehub body (HG) - Cassette Body Type: Shimano/SRAM 8, 9, 10 Speed - Drivetrain Speeds: 9 - Designed for ebike: Yes - Color: ED Black

For Box braking we’ve limited the use of our Oversized Technology to the V area since the levers need to be minimalist and largely act as a remote for the V-Brakes. To reduce lateral deflection at the V we chose to enlarge the pivot areas and arms while tightening tolerances at their interfaces. We robbed material from unloaded sections to reinforce these zones of high stress. Not only are you going to be more efficient with brake power delivery, but you’ll also feel the instant response of deceleration. Key differences: The Box One V-Brake are the only brakes in the Box line-up to be blessed with Oversized Technology. They are also the only model to use sealed precision bearings to further reduce non-rotational movement. The 108mm long-reach brakes are excellent for BMX, mountain, city, urban and tandem bicycles using linear-pull-compatible levers. The 85-mm short reach (AKA mini-V) brakes are an excellent choice for cyclocross or drop-bar gravel bikes.

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.

The Box One Prime 9 Rear Derailleur takes the advantages of our legacy 9-speed drive-train but adds the advancements of a modern 1 by; a fully adjustable Tri-Pack Clutch, and an x-wide cage optimized for an 11-50T cassette. Forged construction steps up the durability and performance to an unparalleled level. Suited for the most demanding terrain.

Our Box Three tier delivers many of the same capabilities of its more famous siblings yet it's built upon a simpler platform. Cassettes are accessible at 11-46T or 11-50T and fashioned with steel spiders. The derailleur exploits our Limited Slip clutch technology without the Tri-pack features. Shift easily with a comparable mechanism, although you'll forgo the hinged clamp and die-cast structure. And lastly, string it all together with a Prime 9 chain but without extravagant coatings. If you're looking to bring your 2/3 by bike into the 21st century, then level up with this group!

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.

The Box Two M30-P crankset is a slightly less acute embodiment of our Oversized technology for cranksets. We squeeze in a show-stopping Praxis™ made 30mm that’s been cold-forged from 7075 T6 aluminum and then painstakingly ground to precision. You’ll be relieved to know this will all fit in a European bottom bracket. The crank arms and spider are poached from the Box One M35 model and as a result, you get all that hollow-forged generosity to help you put that power down. These cranks are engineered for the larger-sized racers. - Oversized Technology™ Hollow Forged Design - Oversized 30mm Alloy Spindle - Self-Extracting Crank Bolt System - 4-bolt 104 BCD Spider with Flex-Resistant Ring - External BSA 30mm BB Included - Weight: 28.6oz - Drive Side Compatibility: Right Hand Drive - Crankset Style: 2-Piece - BB Style: Euro - Chainring BCD: 104 - BB Included: Yes

The Denim Cox signature Grime Grip features a traditional mushroom pattern in the super soft sticky Krayton rubber that you've come to expect from BSD. The design has reinforced slime at the ends for extra durability and a debossed Grime skull with missing teeth, just like Denim... - Flangeless mushroom design made from soft Krayton rubber - Forever bar ends with washers

Simple mushroom style design made of Krayton rubber. - Flangeless slim mushroom design - Bar ends included

Dan Paley signature grips: Dan Paley is really fussy when it comes to grips, not too fat, not too thin, not too squishy, the list goes on. The Dan Paley Slims however are just right. - Flangeless Dan Paley zigzag design - Krayton rubber - Bar ends included

Leezy was cutting the inner flange off his Paley Slims so that the mushroom part of the grip went right to the end. His reason being that that it was comfier to catch barspins on. BSD designed the new Leezus Handles around that idea, coupled with their new softer stickier compound these slim grips feel as good as they look.

The Jonesin' pedal is the little brother of the Safari pedal, designed using the same basic principles of extra hexagonal studs and a true dual concave DX style platform but with a slimmer body for a closer to the axle feel. - Tough nylon fiberglass construction - True dual concave design - Knurled surface for extra grip - 18 optimally placed hexagonal pins per side

The Safari pedal is designed with extra pins in these high impact areas to ensure the pedal stays grippy after withstanding severe abuse. The optimal pin placement, hexagonal pin shape, and knurling all combine to make this one of the most durable, effective plastic pedals in the market. - Tough Nylon Fiberglass construction - True dual concave design - Knurled surface for extra grip - 20 hexagonal pins per side
