## Description

The dfour91, like its sister, the dfour, uses the same gauge as the dzero model drops, but a bolt-on fit to a Shimano drivetrain specifically, Shimano DuraAce 9100. Unlike its predecessor, the dfour, the d9100 is not compatible with Shimano DuraAce 9000, Ultegra, or 105 groupsets, although it is also capable of running Ultegra R8000 chainrings.

The 10K Dynamic Quarq temperature compensation technology graces us with its presence in the Dfour91, relieving us from the constant stress of midrace to zero when temperatures fluctuate over long alpine climbs, or early morning runs on warm days. pm. While making corrections may seem like they come at a minuscule cost of coasting for a couple of seconds, it can make all the difference between the podium and concrete come race day. Not to mention the...
