Unique CeramicSpeed ceramic bearings are premium quality, out-performing mark rivals. The CeramicSpeed Ceramic Bottom Bracket system is so stiff and efficient that additional spacers are not required. At a fantastically lightweight of 84 grams, this CeramicSpeed Ceramic Bottom Bracket is a premium upgrade that your trusty steed deserves.
The pulley wheels are the fastest spinning bearings on your bike, making an upgrade to CeramicSpeed an effective way to save you precious energy. They are extremely wear resistant and will outlive any pulley you have previously ridden. Titanium pulley wheels are extremely resistant to wear. This makes them a great choice if you ride in demanding conditions or just ride a lot. To give even greater protection and reduced friction, a super thin protective coating is applied to the bearing races. This further increases the resistance of the bearing to corrosion or damage from foreign objects. Combining coated bearing races with a titanium pulley wheel creates a pulley wheel with extreme properties in terms of wear resistance and performance. CeramicSpeed titanium pulley wheels are specially designed to reduce friction to an absolute minimum, virtually eliminating the drag associated with standard pulley wheels. The special design helps guide the chain in its ideal line and perform super smooth shifting.
Thanks to the 34mm medium profile, the new Racing 4 DB wheelset from Fulcrum achieves the perfect balance between aerodynamics, riding precision and versatility. They are ideal for climbing without sacrificing stability once the speed increases on the descents. In fact, these wheels have been chosen by the Cofidis team for their training setup.

Taking its name from a phrase coined by fast-jet military test pilots - (we'll let you research that one) - the BTW Speed Suit has been created purely in the pursuit of speed. Castelli utilised CFD analysis, 3D test mannequins, fabric research and testing, numerous wind tunnel tests, and real-world WorldTour riding, resulting in their most aero suit yet. Dimpled shoulders and sleeves deal with boundary-layer aerodynamics while a smooth body is deployed to reduce skin friction and reduce drag to as little as possible. The 3% saving comes at higher speeds, particularly between the 45-65 km/h range, speeds at which races are won and lost. While comfort wasn't the main focus for the BTW, Castelli still uses highly breathable, full-stretch fabrics. An increase in Lycra® content gives a super-snug fit, albeit with a slight reduction in wicking performance. And it doesn't have the same front opening as the San Remo suit, so pee stops are a bit more challenging. But it's a fast suit, and that's what counts. Progetto X² Air Seat Pad The top-end Progetto X2 Air Seatpad is now better than ever. Castelli has improved the shape of the back and improved the method of stitching it in place. The result is it now sits flatter and offers greater comfort. The X2 retains its awesome ventilating perforations, keeping you cooler and drier on endurance rides. The design allows air and moisture to flow directly to the surface fabric for quick evaporation maintaining dryness. A 3-layer component construction also features two densities of foam plus gel pads to provide progressive damping. A super-soft and stretchy next-to-skin layer, with an antibacterial finish, completes this premium pad.
Box Two Prime 9 Speed MTB GroupsetReady for fast and fun MTB adventures, this groupset offers incredibly smooth gearing and precise operation on your mountain bike. It delivers similar performance to the top-tier Box One without the costly features. You still get the Tri-Pack (TM) Clutch in the rear mech only it isn't adjustable. The cassette's 11-50T range is equally impressive and the action on the shifter is just as snappy although you don't get the rigid die-cast pull lever. Completing this groupset is its high-quality chain, which boasts impressive torque power and speed as you explore the trails on your mountain bike.Box Two Prime 9 ShifterThe 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 aluminium 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.Features: Material: Glass Fibre / Nylon Composite, Steel, Aluminum Alloy with Matte Onyx finish Hinged and Extruded Clamp 2 pc Pull Lever / Up to 3 Gears Per Shift* ( two options available to select) Die Cast Top Shell Fast Action Release Lever Prime 9 Technology Multi Shift Option Not Intended for E-Bike Use Single Shift Option Recommended for E-Bike Use Weight 135gBox Two Prime 9 X-Wide Rear DerailleurThe 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 a lower price!Features: Material: Stainless Steel, Hardened Alloy Steel with Matte Onyx finish Tri-Pack Limited Slip Clutch Sealed Bushings Pulleys Nylon Composite Knuckle Pivot-Tech Cable Stay Durable 3D Forged Linkages Forged Inner and Outer Cage Prime 9 Technology Compatible with Standard Derailleur Hangers (Non Direct-Mount) Weight: 290gBox Two Prime 9 11-50T CassetteThe Box Two cassette was where Prime 9 started. Originally conceived as an E-MTB product to deliver long service life and extra range over fewer gears, we quickly grew to enjoy its abilities on unpowered MTBs. All cogs are stamped from steel and subsequently, the larger ones are pinned to alloy spiders. Due to its provenance, this is, without doubt, the most durable cassette in the range.Features: Material: Hardened Alloy Steel, Aluminium Cogs Pinned to Lightweight Spiders Ultra-Wide Ratio with Consistent Progression Prime 9 Technology Our Most Durable Cassette Compatible with HG Freehub Bodies Not Intended for E-Bike Use Weight: 645gBox Two Prime 9 126 Link Chain NickelThe 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. Our unique inner link spacing is engineered to grab those modern wide/narrow chainrings. We chose to modernize the 9-speed platform due to the chain's spirited reputation.Features: Material: Hardened Alloy Steel with Nickel finish Our Most Durable Chain Nickel Plated Protection Durable Hardened Solid Pins Wide/Narrow Chainring Compatible Prime 9 Technology Weight: 350gFAQSHIFTERDoes the Box Two Prime 9 Shifter come with a cable? Yes. All Box Two Twin Lever Shifters come with a stainless steel shift cable.How do I remove the cap from the cable port to install a new cable?

No, Box Prime 9 derailleurs are not currently compatible with drop bar shifters, but we do offer a clamp for our shifters to mount on some 31.8mm drop handle bars.How should I clean my Box Two Prime 9 derailleur? We suggest removing the derailleur from the bike and using a soft bristle brush or rag with soapy water or a mild de-greaser. We do not recommend pressure washing, strong solvents or de-greasers as they could degrade the surface coating.CASSETTEWill the Box Two Prime 9 Cassette fit on a wheel with a SRAM XD Driver? No this will only work with a HG splined Shimano 9-10-11 speed freehub body.Is the Box Two Prime 9 Cassette compatible with other 9 speed drivetrains?
