With the release of the Ultegra R8100 12-speed road group comes a whole new fleet of components, including the R8100 Caliper Set. Though they may not be the shining beacon of the updated groupset, they still offer powerful braking at an impressively low weight, as well as clearance for up to 28mm tires. Dedicated rim brake enthusiasts will appreciate their low weight as well as the smooth modulation offered by Shimano's dual-pivot roller-bearing SLR-EV technology.
