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.

The Box Two Prime 9 Rear Derailleur is very similar to the Box One version however, to be more wallet friendly, it offers a non adjustable Tri-Pack Clutch, bushing pulleys and some muted finishes. Box Two rear derailleurs are still optimized for 11-50t cassettes and offer durability and performance for the most demanding terrain, just at lower price!

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!

Did you know that you can mix and match Prime 9? Can't decide between the modern basics of Box Three and the long service life of Box Two? Well, you don't need to! With this pre-configured and pre-tested option, you'll receive a Box Three cassette paired to the durable Box Two derailleur, shifter and chain. Includes - Box Three Prime 9 Cassette 11-50T - Box Two Prime 9 Chain 126L - Box Two Prime 9 Multi Shifter - Box Two Prime 9 X-Wide Rear Derailleur - Box One Shift Cable & Housing Kit 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.
