Product Description
DFour DUB Power Meter Spider by Quarq
You've been running with power in your cranks for a bit, but craving a drivetrain change. This can be a little tough to stomach, especially when you've been rolling with an expensive power meter that limits compatibility. If your setup involves a Quarq DZero DUB crankset, and Shimano's newest Dura Ace is catching your eye, don't worry, you don't need to lose out on your whole crankset, or compromise your drivetrain desires, with the Quarq DFour DUB Power Meter Spider you can bridge the gap. This spider enables you to keep running your DUB cranks with Shimano's Dura Ace 9100 drivetrains, so you don't have to make concessions anywhere.

DFour's accuracy is further boosted by the return of Quarq's 10k dynamic temperature compensation technology, which alleviates the need for constant, mid-race zeroings in variable conditions. Even if it's just coasting for a few seconds or toggling through your head unit to the proper option, it can still be the difference between winning and losing. It's also obnoxious as hell. The DFour is equipped with an auto-adjust schedule based on a constellation of around 10,000 data points that chart how the unit responds to temperatures ranging from zero to 130 degrees Fahrenheit. This lets the power meter figure out the atmospheric details for you with minimal drift, so you can focus on turning the crank, not babysitting it. Power Balance and Omnical are two additional ...

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
