Result for "carbon fiber boost"
Roam 60 29in Carbon Clincher UST Wheel One Color, 29in, Front

Modern trail bikes maintain composure in situations once reserved for downhill race bikes, and as a result, wheels are now confronted with more abuse than ever. At the same time, riders are demanding bikes that are light enough to comfortably pedal all day. These seemingly incompatible goals are exaggerated on 29-inch wheels. Solving this problem served as the motivation for SRAM to build the ROAM 60 29in Carbon Clincher UST Wheel. SRAM's engineering team must have been tempted to go all-out with the weight reduction of the ROAM 60's carbon rim. Thankfully, though, instead of focusing on shedding grams at all costs, SRAM placed a higher priority on durability. This resulted in the ROAM 60 weighing in within 10 grams of its aluminum counterpart. And this starts to shed light onto why the carbon fiber ROAM 60 is both stronger and stiffer than the aluminum ROAM 50. A quick glance at the cross-section of the rim reveals a main cavity that's thinner on the sidewall than at the bead hook or the spoke bed. The sidewall thins gradually, which provides a strong base for the bead hook. As a result, it resists deforming under hard impacts. SRAM calls this rim profile Taper Core, and it essentially means that SRAM has optimized the carbon layup in order to place more material where it serves durability, not where it doesn't. Ultimately, this results in a thinning of the rim profile elsewhere in order to optimize the balance between weight and strength. The Taper Core rim profile is shared with the alloy ROAM rim, but unlike its alloy counterpart, the carbon ROAM 60 rim gets a boost from SRAM's Carbon Tuned construction. Basically, SRAM combines woven carbon fiber with unidirectional carbon, and the result is a wheel with a precisely tuned blend of stiffness and compliance. The internal construction of the rim employs woven directional fibers, which enables the rim to compress vertically under high loads. This yields an added degree of compliance in comparison to an alumin...

Rise XX 29in Carbon Tubular Wheelset One Color, Predictive Front, Tubular

When you think about the performance advantages that tubular road and cyclocross tires provide -- smoother ride, less rolling resistance, the ability to run lower pressures safely, the lower weight than tire-and-tube combos, and more -- it makes sense that they're massively popular under the pros. Bring those advantages into the world of mountain bikes, however, via the wheel masters at SRAM, and you have something truly ground-breaking: the SRAM XX Rise Carbon Tubular Wheelset, a set ready to dissect the competition, one climb, sprint, and podium at a time. Starting with the rim, SRAM didn't simply beef-up an existing cyclocross or road tubular design, although they did consult the rim geniuses over at Zipp for input. Ultimately, SRAM developed a competition-focused XC race rim with unidirectional carbon fiber and a special resin designed to both mitigate impacts and vibrations to improve ride quality, while also making the rim more durable overall. Not needing to integrate bead-grabbing sidewalls into the rim saved enormous weight while boosting the rim's structural integrity. It's light enough to fly but tough enough to take a beating on par with the toughest XC wheelsets out there, so riders can scratch durability off their list of concerns. The rim then gets laced with 24 Sapim CX-Ray straight-pull spokes in a two-cross pattern, front and rear, to boost the wheels' stiffness and again enhance their toughness. Moving down into the hub, we find SRAM's Speedball ceramic bearings keeping rolling action silky smooth and fast. The rear hub employs the company's new Double Time ratchet mechanism, kicking up the hub's engagement points from an industry average around 24-30 up to 52. Why does this matter? When you resume pedaling after coasting, the more points of engagement in the rear hub, the shorter distance you have to move the pedals before you are actually pushing the bike forward again, as opposed to just "dead spinning."

Lombardia DWR Roubaix Bib Tights - Men's Black, XXL - Men's

Named for the mountains of the region of Lombardia, Italy, the classic Giro di Lombardia race, also known as "The Race of the Falling Leaves," is famous for its wildly unpredictable weather. Following suit, Capo bestowed a rain-and-wind resistant DWR treatment onto one of its most popular cold-weather pieces to create the Capo Lombardia DWR Bib Tights, kicking their protection up a notch without sacrificing weight or breathability. As mentioned, Capo constructed the Lombardia using its proven Thermo Roubaix fabric and threw in a Durable Water Resistant material coating to boost its efficacy in fending off the elements. With a warp-knit construction, this material has a natural stretch. Within the knit, the threads follow a zig-zag pattern along the length of the tights. This allows more surface area coverage while using less material, equating directly to an airy, lightweight construction that still retains warmth. Thermo Roubaix's open weave also accelerates moisture transfer from the skin to the quick-drying surface of the tights, but the precise brushing process is what contributes most to its warmth. After the dyeing process, dedicated machines perform a brush to the inner-lining that provides a high, fleecy, and warming loft. The bib tights' uppers received Capo's super lightweight V-Mesh 360. This open mesh fabric is highly elastic with a supple texture that provides unmatched comfort, support, and freedom of upper body movement. This creates a vertically stable system that stays securely in place along your shoulders throughout your ride. The chamois incorporated into the Lombardia tights is Capo's Anatomic-DP Carbon Elastic Interface Technology (EIT) Insert. Its high-density, open-cell foam is bonded to an antimicrobial microfiber layer that has antimicrobial carbon fiber threads woven throughout. This effectively aids in moisture evaporation, while also keeping the insert neat and tidy. In addition to the slim, movement-freei...

XTR FC-M9020-2 2x Trail Crankset One Color, 170mm, 26/36

The Shimano XTR FC-M9020-2 2x Trail Crankset is a beefed-up version of the likewise controversial-looking but stellar-performing Race crankset. It's reinforced for the heavy-duty riding the Race version isn't, so you can romp around in the wilderness as you please and not feel on eggshells doing so. As usual, Shimano forgoes carbon fiber for crank arm construction, and instead manipulates aluminum into superior function. Using cold-forging, the XTR Trail crankset's crank arms are shaped into a stronger version of the hollow-cavity HollowTech II arms used on the Race cranks. The Trail crank's arms are still technically HollowTech II arms, although they are less hollow and more reinforced for the greater impacts and torsional forces that trail- and all-mountain-riding typically produces. The titanium teeth of the Trail crank's dual chainrings are not likewise hollow like the crank arms (as they are on the Race version), and this is to boost durability. Shift paths between the rings are computer-optimized for smooth and virtually instant shifting, however, and they still retain a similar chain-retaining tooth shape to minimize chain drop. The Trail crank's spider is the same found on all the new M9000-series XTR cranksets, and so it can accommodate any M9000 single- or double-ring combination in the series, although this particular crankset comes with the dual rings, of course.

Rise XX 29in Carbon Tubular Wheelset One Color, Front, QR, 15mm, Tubular

When you think about the performance advantages that tubular road and cyclocross tires provide -- smoother ride, less rolling resistance, the ability to run lower pressures safely, the lower weight than tire-and-tube combos, and more -- it makes sense that they're massively popular under the pros. Bring those advantages into the world of mountain bikes, however, via the wheel masters at SRAM, and you have something truly ground-breaking: the SRAM XX Rise Carbon Tubular Wheelset, a set ready to dissect the competition, one climb, sprint, and podium at a time. Starting with the rim, SRAM didn't simply beef-up an existing cyclocross or road tubular design, although they did consult the rim geniuses over at Zipp for input. Ultimately, SRAM developed a competition-focused XC race rim with unidirectional carbon fiber and a special resin designed to both mitigate impacts and vibrations to improve ride quality, while also making the rim more durable overall. Not needing to integrate bead-grabbing sidewalls into the rim saved enormous weight while boosting the rim's structural integrity.

Roam 60 29in Carbon Clincher UST Wheel One Color, 29in, Rear

Modern trail bikes maintain composure in situations once reserved for downhill race bikes, and as a result, wheels are now confronted with more abuse than ever. At the same time, riders are demanding bikes that are light enough to comfortably pedal all day. These seemingly incompatible goals are exaggerated on 29-inch wheels. Solving this problem served as the motivation for SRAM to build the ROAM 60 29in Carbon Clincher UST Wheel. SRAM's engineering team must have been tempted to go all-out with the weight reduction of the ROAM 60's carbon rim. Thankfully, though, instead of focusing on shedding grams at all costs, SRAM placed a higher priority on durability. This resulted in the ROAM 60 weighing in within 10 grams of its aluminum counterpart. And this starts to shed light onto why the carbon fiber ROAM 60 is both stronger and stiffer than the aluminum ROAM 50. A quick glance at the cross-section of the rim reveals a main cavity that's thinner on the sidewall than at the bead hook or the spoke bed. The sidewall thins gradually, which provides a strong base for the bead hook. As a result, it resists deforming under hard impacts. SRAM calls this rim profile Taper Core, and it essentially means that SRAM has optimized the carbon layup in order to place more material where it serves durability, not where it doesn't. Ultimately, this results in a thinning of the rim profile elsewhere in order to optimize the balance between weight and strength. The Taper Core rim profile is shared with the alloy ROAM rim, but unlike its alloy counterpart, the carbon ROAM 60 rim gets a boost from SRAM's Carbon Tuned construction. Basically, SRAM combines woven carbon fiber with unidirectional carbon, and the result is a wheel with a precisely tuned blend of stiffness and compliance. The internal construction of the rim employs woven directional fibers, which enables the rim to compress vertically under high loads. This yields an added degree of compliance in comparison to an alumin...
