Specialized Power Cranks Dura-Ace Dual
$1,500.00
No matter your skill level or experience on the bike, there's no better way to enhance your training and racing performance than by riding with a power meter. And for all of you Dura-Ace fans out there, we've combined our extremely light power sensors with a Shimano Dura-Ace crankset to give you the most accurate and precise power meter available. The development of Power Cranks began with our Human Performance Team looking at riders in realistic scenarios on the bike. Historically, power meters have been validated by two different methods—one is by measuring the produced torque by applying a static, linear load to a crankarm or chainring, while the second uses a power generating motor to pedal the bike. Well, cycling is neither static nor linear, and humans apply power much differently than a machine. So, we found that neither of these methods answers the "real-world" accuracy question. To get the best test for accuracy, in all types of riding scenarios, we built our own cycling treadmill, the WinMill, to measure power output to a known truth. This new benchmark lets us evaluate accuracy under all riding conditions—seated versus standing, various power and cadence levels, different weights, and a myriad of gear. This data acquisition process is our gold-standard for testing power meters, and through our testing and external validation from the Locomotion Lab in Boulder, Colorado, Power Cranks have been proven to have the highest accuracy in real-world scenarios (+/- 1.5%). The Dual-Sided S-Works Power Cranks utilize separate strain gauge systems to individually measure the effort produced by each leg. This maximizes the accuracy of your total power numbers, plus it helps you to better understand your performance as fatigue increases and when you're recovering from injury. And with class-leading temperature compensation firmware and waterproof enclosures, Power Cranks are easy to live with. Calibration is only required during seasonal-type fluctuations in temperature, and the included wrench makes battery swaps a breeze. - +/- 1.5% real-world accuracy tested on the WinMill and validated by the Locomotion Lab in Boulder, CO - Independent, dual-leg power measurement - Works with ANT+ and Bluetooth devices - Easy set-up and diagnostics with the Specialized Power app. (iOS and Android versions available) - Available in 170-175mm crankarm lengths - All models include 52/36T chainrings

Specialized RockShox SID WC with Brain
$1,300.00
Sure, there are plenty of lightweight XC forks out there, but racing demands so much more. Nimble handling, gram-obsessed weight, buttery damping—combined, they all make the difference between a good fork and a great fork. And with this in mind, the all-new RockShox SID World Cup Brain fork has been completely redesigned to meet the demands of XC racing, and hyperbole aside, we can confidently say that it sets the bar for race-worthy performance. The all-new Brain damper uses position sensitive technology for better chassis balance and traction. It does this while retaining the ability to separate rider input from bump events on the trail—just some of the incredible stuff that Brain is known for. The new technology can now remain active during the initial 25mm of travel, and this creates a much more balanced riding position and supple front-end feel. In turn, this goes a long way in reducing rider fatigue. And although the fork feels more active initially, as soon as you standup to get on the gas, the forward shift in weight naturally compresses the fork into the platform. So yeah, you'll feel well supported and efficient during hard sprint efforts. Incredibly, Brain does all this while keeping you in control and riding smooth on rough terrain without any need for extra cables and lockout levers on the handlebars. The World Cup Brain edition of the SID is not just a slight upgrade over the RLC and XX models, either. Along with the integrated Brain technology, it utilizes a carbon fiber steerer and crown, which reduce weight by over 100 grams and increases the overall stiffness. Also adding to the stiffness of is the short-travel-specific design. Leaving the 120-millimeter segment to the trail category, RockShox’s engineers were able to focus on the 80- to 100-millimeter travel range, and therefore develop lighter and stiffer uppers and air shafts. This new design, along with SRAM's Torque Caps (they create an enhanced interface between the hub and fork dropout), Power Bulge technology that reinforces the lowers, and 110-millimeter Boost spacing, keeps torsional stiffness high, allowing you to point-and-shoot while descending. Last, but certainly not least, on the feature spec is the Solo Air spring that’s customizable with RockShox’s Bottomless Tokens. The Solo Air spring lets you adjust pressure with a single Schrader valve that controls the pressure in both the positive and negative air chambers, making adjustments to pressure simple and intuitive. To customize ramp-up preference, RockShox’s Bottomless Tokens can be added to create a suspension curve that’s custom to your preferences. - Tapered Full Carbon Steerer tube - Top-adjust Brain damper w/ Position Sensitive technology - 110mm spacing with Torque Cap compatibility - 100mm of travel
RockShox BoXXer Team (26-inch)
$1,275.00

To make that happen, this fork features the groundbreaking Charger damper for excellent mid-stroke support and a bottomless feel. The BoXXer also has RockShox's 20mm Maxle Lite DH through-axle and big 35mm Fast Black stanchions. Combined, this chassis has the stiffness you need for surgical steering precision to hold the tightest lines on any track.
