Bicycle Cranks

Osymetric Shimano/SRAM 130mm BCD - If you watched so much as one stage of one Grand Tour this year, you saw some of the riders occupying the top spots riding the Osymetric Chainrings. But, if you're like most people, you were scratching your head every time the camera panned to the drivetrains. Not quite an oval, and certainly not an ellipse, the Osymetric Chainring is its own shape — and we're happy for that. Oysmetric delivers greater efficiency, increased power, and requires less user effort than standard round rings.

Shimano SLX FC-M670 10-Speed Crankset - 42/32/24 - The Shimano SLX FC-M670 10-speed triple crankset offers a stiff, rugged design that will meet the challenges of demanding trail riding so you can shred in confidence season after season.

FSA SL-K Light Compact EVO 386 - Innovation in the cycling industry is something of a double-edged sword. On one hand, it spurs the development of new and exciting technologies that genuinely improve the sport we so dearly love. On the other, it runs the risk of creating a dizzying array of unnecessary standards that accomplish little more than confusion and derision before petering out. Luckily, the latter does not apply to FSA's new EVO 386 bottom bracket platform--a genuine improvement over BB30 that offers frame manufacturers the means to further innovate on frame designs that potentially improve overall ride quality and frame performance.

Shimano XT Dyna-Sys FC-M785 Double Crankset - With 10-speed cassettes having 36 tooth big cogs, the door was opened for re-evaluation of the standard triple crankset. For many riders, some of the available gear options would be redundant and unnecessary with a 3x10 setup, not to mention some gears at the bottom or top of the range would generally be unused. And since we all quest for simplicity and lightness, 2x10 drivetrains make a lot of sense.

Shimano XT Dyna-Sys FC-M780 Crankset - Triple - Following the XTR model, Shimano's trail-tested XT group now offers more options that help tailor the components to suit your riding preferences or favored terrain. This Shimano XT 3x10 Hollowtech II Crankset FC-780 is like its 770 predecessor in many ways, notably the Hollowtech II construction that ensures its stiffness, strength, and lightness. However, XT 780 cranks are now available as 2x10 or 3x10 configurations like the one here.

FSA ATB Chainring 64mm - 22 Teeth - This FSA Pro ATB mountain bike chainring is precision CNC-machined out of 7075/T6 aluminum for quick and easy shifting. Imported. Laser etched logoBlack anodized aluminum with CNC silver teeth.

Shimano FC-CX70 Crankset - The FC-CX70 Crankset is Shimano's Ultegra-grade crankset for cyclo-crossers. The design focuses on stiff, lightweight performance in all kinds of conditions to sunny road riding to nasty, muddy slop..

Sram XX1 BB30 Crankset - 156 Q-Factor - SRAM's pursuit of seamless and simple component integration shows it continually innovating the component industry -- case in point being the XX1 group. As a whole, XX1 works as an efficient machine, but individually, each component plays a vital role in making this group the trendsetter that it is. The XX1 BB30 Crankset sets itself apart from others with its game-changing design and the Zen-like simplicity that comes from running a single chainring.

Sram Red 22 BB30 Crankset - The BB30 system continues its reign over the peloton as a preferred bottom bracket standard. It's not hard to see why, as an oversized, 30mm spindle and large bottom bracket shell add torsional stiffness, providing a responsive and efficient pedaling platform without increased weight. The system's direct fit, press-in bearings also eliminate the need for aluminum bottom bracket cups, further reducing weight. With the technology licensed from Cannondale more than a decade ago, a multitude of manufacturers now produce BB30-compatible products.

Shimano XT M770 Chainring 64mm - 22 Teeth - Replace your worn inner chainring with this Shimano Deore XT M770 ring to revitalize your drivetrain. Imported.4-bolt design and 64mm diameter fits multiple Shimano cranks, such as Deore, LX and XTXT quality supplies durability and light weight.

Sram Rival Crankset with GXP Bottom Bracket - Comparing any SRAM Rival component to its Red counterpart is an easy task. Why? Well, because SRAM makes the story so easy to follow. Rival and Red components are functionally identical across all component types, and what makes Red feel so special (shifting, braking, ergonomics, etc) carries directly into the Rival line. There are, really, only two lines of distinction — weight and finish. In terms of weight, the Red crankset is so feathery because the arms and spider are both built from carbon fiber.

Shimano XT FC-M780 10-Speed Crankset - 42/32/24 - The Shimano XT FC-M780 10-speed crankset is specially designed for aggressive all-mountain riding. Imported. Hollowtech II technology maximizes stiffness and decreases weightThe Shimano XT FC-M780 10-speed crankset is designed to work with a 10-speed rear cassetteSteel/carbon composite middle ring adds rigidity for better shifting, increases service life and smoothly delivers power to the cassette42T - 32T - 24T chainrings create a close ratio gear combination.

Rotor Road Inner Q-Ring - Rotor Road Inner Q-Rings are designed to capitalize on the strongest part of your pedal stroke and minimize the negative effects of the weak portion known as "dead spots." The Q-Rings have a subtle oval shape and, with multiple mounting holes, can be "clocked" to maximize the effects of your biomechanics, pedaling style, and bike geometry. And aside from those benefits, the shift pins and ramps on the Q-Rings have been redesigned to provide faster shifting.

Campagnolo Super Record 11 Ultra-Torque Titanium EVO Crankset - While Campagnolo's Super Record components signify its engineers' best efforts, Campagnolo just couldn't leave them well enough alone. This Super Record 11 Ultra-Torque Titanium EVO Crankset replaces the steel crank spindle that's normally used, with a titanium version that's 25% lighter and just as strong. The bolt for the Hirth joint (what fastens the two halves together) has also been constructed from titanium in order to save another few grams.

Rotor Round Road Outer Chainring - While Garmin-Cervelo's Q-Rings converts Heinrich Haussler and Christian Vande Velde win races and build form towards July aboard Rotor's non-traditional ovalized chainrings, not everyone on the team made the switch. Cameron Meyer is one rider on the team who depends on Rotor's standard round chainrings. In fact he rode them to his overall win at the Tour Down Under. These Rotor Round Road Outer Chainrings are built in identical fashion to their Q-Rings, save for the ovalized shaping.

Shimano 105 Chainring 130mm - 39 Teeth - Replace your worn middle chainring with this Shimano 105 ring to revitalize your drivetrain. Imported.5-bolt design and 130mm diameter fits Shimano 105 triple cranksAluminum alloy is lightweight and durable.

Sram Force 22 GXP Crankset - While the announcement of 22 gears might draw most people's attention toward the new Force 22, we'd argue the biggest achievement of the new group was SRAM's generous carryover of Red's technology. The Force 22 GXP Crankset showcases this most clearly, as it was constructed with unidirectional carbon crank arms and received Red's hidden bolt pattern and innovative 'True 22' X Glide R chainring calibration, giving you the ultimate in drivetrain power and precision.

Sram Red GXP Quarq Power Meter Crank - SRAM and Quarq have once again put their best technologies forward to create the new Red 22 Quarq Powermeter - BB30 cransket. The original 2012 joining of the masterminds resulted in the Red crankset seamlessly pairing with Quarq's top-end powermeter, which is why both revered manufacturers once again decided to combine their forces for the new power system. The finished product is a precise combination of accurate power data and the most advanced crankset technology that's been proven, and continually put to the test, by the best cyclists in the world.

Sram XX1 Chainring - SRAM's XX1 is a fresh approach to drivetrain designs that builds on proven, and preferred, principles of established riders and racers alike. One-by setups are nothing new, but none have offered the ratio spread, chain retention, and performance driven technology that this 11-speed group does. The single front chainring, in fact, packs as much design time as some multiple-cog cassettes. Take a look at the tooth profile, and its shape is decidedly unique.
