Whether you are considering adding a power meter to your training arsenal, or are just looking to protect your cranks with a set of crank boots, JensonUSA.com carries a wide variety of bike crankset parts and accessories.

Power meters, such as those offered by Stages, Race Face, and Easton, measure your actual power output represented in watts. Most power meters use strain gauges that track torque applied to some area of your crankset such as the spider or a crank, as is the case with Stages power meters. It’s technology that was first adapted in the 1980s by professional riders such as Greg LeMond, and now sees wide use by both pro and amateur cyclists, who use power output data to gauge on-bike efforts in real time and also track training progress.

Crank boots, meanwhile, protect the end of your crankarms from rock strikes, and can also be a fun way to add some colorful flare to your drivetrain. For instance Race Face Carbon Crank Boots come in seven colors, and fit cranks from Race Face, SRAM, Shimano, and FSA.

This catch-all category also includes an array of spindle and axles such as the Stages Spindle for BB30, which is aimed at riders using a Stages Carbon crank-based power meter, assuring proper crank alignment and Q-Factor, which is the distance between pedal attachment points on your crankarms.

JensonUSA’s bike crankset parts and accessories inventory is also your go-to source for critical pinch and standard crankarm bolts, with options from brands like Shimano, FSA, Race Face, Truvativ, Campagnolo, Profile Racing, SRAM, and Wheels MFG.
