Can­non­dale CAAD12 Disc Dura-ace $6,000

Can­non­dale has been pro­duc­ing some of the best alu­minum frames around through its caad se­ries. The lat­est in­car­na­tion, the caad12, comes in a ver­sion with Shi­mano’s top-tier hy­draulic disc-brake sys­tem, the Dura-ace 9100. The Ja­pan­based com­pany takes care of the shift­ing (front and rear mechs, and chain), too. Can­non­dale turns to its own, rock­solid Hol­low­gram Si crank, with 52/36-tooth rings, to round out the driv­e­train. While the price is in the range of a good car­bon-fi­bre ma­chine, the per­for­mance of this al­loy rig is also com­pa­ra­ble. ( can­non­

Scott Ad­dict 20 Disc $5,200

The Ad­dict 20 Disc is Scott’s mid-range, light­weight racer. It’s equipped with Shi­mano’s Ul­te­gra 6800 front and rear de­railleurs and crank. Shi­mano’s st-rs685 levers, br-rs805 calipers and 160-mm-di­am­e­ter ro­tors take care of the hy­draulic brak­ing. The Ad­dict 20 is roughly 8 kg, which makes it quite nice on a long climb. The disc brakes are then great for manag­ing your speed be­fore the hair­pin turns on the way down. ( mi­cas­

Opus Vi­vace 2 $3,500

Opus’s disc-brake road ma­chine, Vi­vace 2, is out­fit­ted with solid Shi­mano 105 parts. Stop­ping power comes via the trp HY/RD flat-mount calipers. The brakes have ca­bles that ac­tu­ate the sys­tem’s hy­draulic com­po­nents. For added stiff­ness and pre­ci­sion, the Mavic Ksyrium Disc wheels are locked into the dropouts with 12-mm thru axles. There are some well-thought-out over­laps in the ge­om­e­try across the five sizes of Vi­vace to make find­ing the right fit – whether that’s aero or up­right – eas­ier. ( opus­
