Built for tackling everything from Enduro World Cup courses to fast and flowy shuttle runs, the Pivot Firebird compromises nothing in your search for all-mountain versatility. 170mm of front and rear suspension travel lets you confidently blaze through washed-out rock gardens, and the combination of long reach, long front center, and short chainstays provide the high-speed, playful agility we're all after in a long-travel bike. What really sets this bike apart, though, is the pedaling efficiency offered by the dw-link rear suspension design. Pedaling such a leggy machine can seem daunting, but the Firebird's geometry and efficient suspension platform urge you to climb higher to score maximum reward. The Firebird Team XX1 Eagle build gives you the massive gear range that SRAM's incredible XX1 Eagle drivetrain provides to give you the advantage no matter where you ride. SRAM Guide Ultimate brakes supply both power and modulation in volumes, while Industry Nine hubs laced to Reynolds Enduro Carbon rims, all wrapped in wide, toothy Maxxis Minions leave nothing to be desired in the strength and traction departments. Fox suspension components precisely complement the Firebird's character with a 36 Factory fork and Float X2 Factory shock, while a Fox Transfer dropper seatpost wraps up this clean build that's ready to shred your favorite jump line, park run, or enduro race straight off the showroom floor.

We created the endurance road category two decades ago proving that high ergonomics means high performance. Today, the new Roubaix SL8 with Future Shock 3.0 is lighter, faster, and smoother than any road bike ever made, unleashing unmatched confidence. The road may be hell below, but on Roubaix, it's always heaven above. - COMPLIANCE: Future Shock 3.0 is the star of the show, more tunable, adjustable, and durable than ever. Now, regardless of position on the bike, every rider experiences 20mm of smooth, stiction-free travel between the stem and head tube. Future Shock helps keep your hands and bars steady for a smoother ride with more control to stay fast, safe, and confident. - Our dropped clamp design exposes more seatpost to increase deflection, but "more" isn't simply better. The Pave seatpost controls that deflection for the optimal vertical compliance. Together they create 'Cobble Gobbler' technology, and when paired with the Roubaix's rigid rear triangle, deliver a smooth ride with no loss in efficiency. - The Roubaix SL8 is the smoothest road bike our Ride Science Team has ever tested-reducing impacts at the bars and saddle by 53% vs. the nearest competition. With Roubaix's Future Shock 3.0 the wheel quickly moves over the bump, while rider mass remains stable, maintaining momentum in rough terrain. Typical forks deflect backward on impact, causing a measurable loss in speed. It's a scientific fact, smoother is indeed faster. - CAPABILITY: The Roubaix pioneered endurance geometry, so you ride "IN" the bike, not "ON" the bike to relieve pressure on your hands, arms, and shoulders for capability and confidence on any road, yet it's ready to dissect a mountain decent at full gas. Snuggle up. - With tire clearance up to 38c/40mm, this endurance road machine delivers better traction than ever on rough roads and even light gravel. Thanks to lightweight, super-efficient Specialized tires, that extra tire volume and traction comes with no downsides. - Roubaix inspires really BIG days on the bike, so we've given it every mount your adventures could need- three bottle mounts, top-tube mounts, and it's even fender-ready. So, go ahead and bring it all along for the ride. - PERFORMANCE: The new Roubaix SL8 is our most aero yet, with new aero shapes from our Free Foil library and dropped seat stays. At just 825 grams, the frame is 50 grams lighter, utilizing lessons learned from the Aethos—the world's lightest production frame—and our premium Fact 12r carbon blend. Nothing in its class is faster or lighter than the Roubaix.

The Soloist. It's a name from deep in our history, but immediately familiar to anyone with bike racing memories extending back to the early-2000s. It was the weapon of choice for top World Tour contenders on CSC and the Cervelo Test Team, and we're bringing it back for a new generation. The new Soloist is designed for the week-in, week-out rider and racer who can only justify one high-performance bike. It balances lightweight and aerodynamic advantages to deliver a bike that really is 'just right'. Soloist comes in a hair lighter than S5, but significantly more aerodynamic than R5, and borrows the threaded bottom bracket standard you find on the R5-CX. It's a race bike that can accommodate mechanical and electronic shifting, can hammer out the training miles in all weather, and yet still has the chops to leap off the front at that decisive moment. That's the Soloist. FAST LIKE S5, LIGHT LIKE R5 Soloist sits right between S5 and R5 on the performance scale, while having a price tag that's less World Tour, more Road Trip. It's about 250g heavier than R5, and 250g lighter than S5. It's 190g slower than S5, but 126g faster than R5. You get the idea. It's the 'just-right' answer for the rider trying to find a smart, intentional compromise. LOOKS LIKE A RACE BIKE, RIDES LIKE A RACE BIKE We took the handling geometry for the Soloist directly from R5. The R5 is beloved by pros and amateurs alike for its poise, stability, and precision when that killer climb turns into an even more killer descent. Soloist benefits from our decades of race bike geometry development, and comes out of the gate ready to go. HIDDEN FROM THE WIND, NO BLEED NECESSARY The cable routing is inside the frame for aerodynamics, but doesn't go through the stem. We developed our own system that threads the cables under the stem, but through the bearing cap. Whether your position changes or you loan the bike to a friend who uses a different stem length, you won't need to bleed the brakes to swap the stem. CLEARANCE TO BUZZ THE TOWER The Soloist fits tires up to 34mm (measured), and wheels wide enough to support them. BBRIGHT-47 The BBRighT-47 bottom bracket, which first appeared on the R5-CX, is ideal for those who log big miles but don't have a pro wrench checking the bike over every day. It makes BB swaps a breeze (convenient if you're burning through hand-me-down components) and extends the life of the frame.

A Fair Advantage We tapped into everything we've learned from years of making the highest quality carbon full-suspension bikes and added the super-efficient Superlight suspension to make a World Cup-winning XC race bike. The Blur isn't guaranteed to make you a race winner but being the lightest, full-suspension carbon XC bike we've ever made, it might be the difference between claiming first place...or just crossing the line. SRAM Eagle Transmission - stronger, better shifting, wirelessly The next generation SRAM Eagle Transmission specced on our CC-carbon models is a radically robust, fully integrated and interdependent wireless transmission. Built around the universal constant of the wheel axle itself, the Full Mount hangerless attachment creates a far stronger connection to the frame and the super strong derailleur provides unprecedented strength. Shifting under load is made possible due to a combination of X-SYNC technology and cassette mapping, creating seamless shifts even during your hardest power output. The new AXS Pods are extremely ergonomic and highly customizable, so shifting gears is light and intuitive. It's simply the most advanced transmission and nearly as tough as the mountain itself.

The Blur isn’t guaranteed to make you a race winner but being the lightest, full-suspension carbon XC bike we’ve ever made, it might be the difference between claiming first place...or just crossing the line. Design Details: - SRAM Eagle Transmission - stronger, better shifting, wirelessly The next generation SRAM Eagle Transmission specced on our CC-carbon models is a radically robust, fully integrated, and interdependent wireless transmission. Built around the universal constant of the wheel axle itself, the Full Mount hangerless attachment creates a far stronger connection to the frame and the super strong derailleur provides unprecedented strength.

The new AXS Pods are extremely ergonomic and highly customizable, so shifting gears is light and intuitive. It's simply the most advanced transmission and nearly as tough as the mountain itself. - XC or TR The TR builds feature more travel (115mm rear, 120mm front) slightly beefier tires (Maxxis Rekon), a full height adjust dropper post, no lockout remote, and larger brake rotors. It's not a trail bike, it's an XC bike for certain courses. - Light Carbon Frame The full-suspension Blur is lighter than most pre-race dinners you'll eat - 289g saving over the previous generation. - Reserve 28 XC wheels This is the lightest Reserve MTB rim (385g or 1367g complete). The rim bed is shallower and wider, meant for the newer generation of higher volume XC tires which are popular with elite racers. - Geo to match The Blur's chainstay length is matched to frame size so every rider, no matter their height, gets the same balanced geometry and bike fit. - Two water bottles Two water bottle mounts within the front triangle mean there's enough juice (or whatever electrolytes you choose) to keep the engine running. - No proprietary gubbins There are no fiddly proprietary parts that could leave you stranded in a Cape Epic or Breck Epic campsite. - Made to last many lifetimes The legendary Santa Cruz fit, finish, and quality construction put this into a league of its own. The frame, bearings, and optional Reserve wheels come with a lifetime warranty and any service is easy to do with our Rider Support pledge. - Chainguide The only thing you'll be dropping is your competitors. - Superlight™ Suspension Our priority with the Blur was to ensure that every kilojoule of a rider's energy is translated into forward thrust. That meant making something lightweight but also really efficient. This is the (super)lightest suspension we've ever made. Frame Sizing If you're on the cusp between the recommended height range of two sizes, the absolute best thing is to try to ride them both. At a minimum, check the stack/reach measurements on your current bike and compare it to the new model you are looking at to get an idea of a fit you are already comfortable with. If riding the bike is not an option, consider the following. Personal Preference A larger size frame will be more stable and will give you more room to move without upsetting the weight balance of the bike. The larger size will put the front wheel further in front of you, which gives the feeling of security and conversely, it will require more significant body movements when you WANT to shift the weight bias of the bike. Think hard about your riding style and how active/intuitive you want it to be vs. stable and speedy. You'll need to work a bit harder to muscle the larger bike around. Body Dimension Not all bodies at a given height are the same. If you have longer legs and a shorter torso than the average person your height, that may push you towards the smaller of the recommended sizes. If you're all torso and arms, most likely you'll want to size up.
