MRP AMg V2 Carbon

The contact-free, "upper-only" chain retention means the All-Mountain Guide will be virtually silent and completely drag-free when pedaling. The patented integrated skid will protect your crank and chainring and prevent the chain from ever contacting and potentially damaging your expensive frame. - Perfect for "clutched" 1x10 and 1x11 drivetrains, as well as those using chain-retaining rings (like our Wave Ring) - New nylon integrated skid protects chainrings and glides over rocks and obstacles - Tracked and grooved upper guide / backplate interface increases stiffness and eases installation - New co-molded "TR" upper guide with softer durometer interior for silent guidance - Available in 28-32t and 32-38t sizing - All install and adjustment operations possible with just a single 4mm HEX wrench. - Compatible with chainlines 49mm and wider
MRP SXg Alloy
$169.95
With the SXg, MRP delivers a guide without compromise and with no equal.

It’s a guide that refuses to be pigeon-holed, blurring the lines between typical industry definitions - a little country and a little rock, as they say. But, in this case, it’s a whole lotta rock.

Specialized Power Cranks - Shimano 105 Upgrade Kit
$381.95 $425.00 10% Off
Whether you're looking to take your training to the next level or you simply want a better way to measure energy expenditure, a power meter is your best bet. And the Power Cranks 105 Upgrade Kit are no exception. With our lightweight power sensors on a Shimano 105 crankarm, it's the perfect way to enter the power meter game. 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 Power Cranks are also easy to live with, with class-leading temperature compensation firmware and waterproof enclosures. 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. - Works with ANT+ and Bluetooth devices. - Easy set-up and diagnostics with the Specialized Power app. (iOS and Android versions available). - Shimano 5800 generation 105 left-side power measurement. - Right crankarm and spider NOT included. - Available in 170-175mm crankarm lengths.
