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 One cassette is a piece of art that brings together all the virtues of the Prime 9 philosophy and distills them into what we feel is our most defining product to date. A unique machined all-steel unibody lattice and alloy support disc have netted us a high-performing, simple, durable and lightweight cassette. With only 350 grams of weight we know that this is what the riders need. Enjoy the simplicity and ride this piece of history.

When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency. Key differences: This particular model fork pushes our Oversized Technology to the extreme as it includes the 1.5 to 1-1/8 inch tapered 7000 series aluminum steerer tube and stiffer 20mm through-axle cold-forged dropouts. Say goodbye to deflection. Weight Limit: 115kg (253 lbs) with limitations as per Category 2 of EN 16054:2012 Standard FEATURES - Oversized Technology™ - Tapered Steerer Tube to Reduce Deflection - 20mm Through Axle to Increase Responsiveness - Internal Butterfly for Added Durability at Steerer Tube and Fork Crown Interface

All Box One and Two cranksets are engineered and crafted using our Oversized Technology. we all know that there is no use pushing hard on your pedals if you can’t deliver most of that power to the rear wheel. During the creation of our cranks, we were obsessed with Power delivery AKA pedaling stiffness. To reduce lateral deflection at the bottom bracket we chose to enlarge the spindle and the crank arm’s interfaces. We robbed material from unloaded sections to reinforce these zones of high stress. Not only are you going to be more efficient with power delivery, but you’ll also feel the instant response of acceleration. Seen through another lens, less energy will be required to achieve the same elapsed time. Key differences: The Box One M30 crankset is just as tyrannical as its big brother the Box One M35. Since it's designed for the smaller rider the now 30mm spindle is as extreme to a smaller rider as the 35mm is to a burly world champion. The crank arms are hollow-forged but reduced in size for their application. It is possible to add too much stiffness where the rider will not feel the benefits. Going beyond that point simply adds material which is surplus weight. We’ve removed the stabilizer rings from the spider and removed unneeded material from its legs. These cranks are engineered for smaller-sized racers. FEATURES - Oversized Technology™ - Hollow Forged Design - Large 30mm Alloy Spindle - Self-Extracting Crank Bolt System IMPORTANT NOTES - BB86 frames require Praxis™ part 86-4001B or 86-4001W. - BB30/PF30 frames require Praxis™ part 68-4001R or 68-5401R. - T47 frames require Praxis™ part 47-0000. - Do not use pedal washers when installing pedals onto these cranks. M30-M cranks were designed to be used without pedal washers. COMPATIBILITY - Box Two Chainring - Box One Chromoly Chainring Bolts - Box One 7075 Alloy Chainring Bolts - Box Two Oversized bottom bracket M30

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 new Super Record 12x2 Speed mechanical front derailleur: lightness, design, fluidity, and effectiveness. The new Super Record 12x2 Speed mechanical front derailleur introduces many new techniques, starting with the leverage systems designed to speed up derailings. Less effort is needed to shift owing to the split front connecting rod, which prevents contact with the travel limit screw. Whilst the shape of the inner cage plate is engineered to guarantee maximum readiness for upshifting, the external monolith body in carbon fiber has been shaped to enhance the efficiency of the chain movement when going uphill and the readiness and fluidity in descent. The aesthetic impact of the component is consistent with the rest of the Super Record groupset due to the use of unidirectional carbon fiber and titanium stop screws. Micro-adjustments to the front derailleur position, which can be activated by the controls, help to prevent any contact with the chain, even in the case of maximum crossover. As regards compatibility, the new Super Record 12x2 Speed front derailleur allows the use of hoods measuring up to 32 mm thanks to the new upper connector rod and the double fixing position of the control cable.
